Larger tires and plus sizing? (TOP 5 Tips)

A Plus Sizing rule of thumb is to increase tire width by 10 millimeters and decrease sidewall height by 5 to 10 percent for each 1-inch increase in wheel diameter. You will often find only +/- a few tenths of an inch difference in the overall diameter of the tires, as shown.

  • Plus sizing is when the tire and wheel combination is changed out for a larger wheel and lower profile tire. It is a popular option since most people like the look of a larger wheel. But it is important to know that plus sizing your wheel and tires will also change the performance of the vehicle.

What happens if you put a bigger size tire on your car?

When you put bigger tires on your car, SUV, crossover, or light truck, you raise the vehicle’s clearance — increasing body roll and load transfer, which may negatively impact your car’s balance and speed.

How much bigger can you go on tire size?

As a general rule of thumb, it’s safe to fit a tire up to 20 millimeters wider than stock on the original rim. The actual width of the tire will vary depending on the width of the rim: The tire will expand 5 millimeters for every half inch (12.5 millimeters) increase in rim width.

When installing new rims and tires What is plus sizing?

Plus sizing is done by selecting equivalent overall tire diameters and load capacities to your original equipment —by pairing lower profile tires with larger diameter wheels. That way your speed and load rating will still meet the requirements set out by your vehicle’s manufacturer.

Are larger diameter tires better?

The larger the wheel, the shorter the tire’s sidewall and the wider its tread must be to maintain the same outside tire diameter and prevent reducing the tire’s load-carrying capacity. The shorter and wider the tire, the better the handling and cornering grip.

Can I use 265 tires instead of 255?

Since you only specified the first, I can only tell you that the 265 is 10mm wider than the 255. It’s important to note that the outer diameter (how far the wheel rolls in one revolution) is slightly more for a 265 than a 255 at the same aspect ratio as the sidewall would be larger.

Can I use 165 tires instead of 175?

Yes, you can replace the 165 tires wit 175 tires. The circumference of the 175/65 is slightly smaller so your speedometer will read slightly lower than it did before for any given engine speed.

Do bigger tires affect transmission?

Changing tire size doesn’t affect your transmission, but it does change your final drive ratio. The effect is the same as if you had changed your transmission. How much difference you have depends on how different the tires are compared to the stock tires. Larger tires will lower your final drive ratio.

Can you use 245 tires instead of 225?

245 and 225 are both tire size not rim sizing. You need to figure out what size rims you have. An example of rim sizing would be 8×18 that would be 8 inch wide and 18 inch diameter.

Do bigger tires lift your truck?

The benefits of bigger wheels Larger wheels do lift a truck higher into the air, increasing ground clearance. But the increase in wheel size has additional benefits. A larger wheel means larger tires can be fitted to the truck.

Are plus size tires worth it?

Plus tires generally measure between 2.8”-3.0” wide, which slots them in between traditional mountain bike tires that measure 1.9”-2.6” and fat bikes tires that are 4.0”-5.0”. The benefit of a bigger tire is obvious. More tire means more rubber touching the ground, which in turn means more traction. Great!

Can I use 225 tires instead of 215?

The diameter of 215 tires is much smaller than 225 models. Also, the aspect ratio of 215 tires is slightly higher compared to 225 tires. Therefore, there might be a minor change in the steering stability of both tires if used interchangeably. To sum up, yes, 215 and 225 models are interchangeable.

Will 275 tires fit 265?

There is no specific width to run a 265 or 275. Most of the time they will fit on the same wheel. It all has to do with size, sidewall, and manufacturer.

What does 33X12 50R20 mean?

33X12.50R20. Diameter: 33.0′ Width: 12.5′ Wheel: 20′ x 8.5-11′ Sidewall: 6.5′

What is the advantage of 19 inch wheels?

On the performance front, the 19-inch tires reportedly allow for sharper turn-in and more mid-corner balance, whereas the 17-inch tire felt more vague. This back-to-back-to-back examination of tires on the same course under the same car is the perfect way to test a set against another.

Can I use 235 tires instead of 225?

235 tires are one of the strongest, most durable, and reliable tires available for sub-heavy vehicles. 235 tires are also preferred over 225 tires for professional stunting because they offer much more stability to the vehicle and hence are much safer.

Can You Put Bigger Tires on Your Vehicle?

Generally, the response to the question, ‘Can I put wider tires on my car?’ is a resounding ‘It depends.’ Before you go out and purchase that new set of wheels, there are a few things you should be aware of when it comes to installing larger tires on your vehicle. However, while there are several advantages to larger tires, potential purchasers should take into consideration how larger tires effect vehicle stability, safety, fuel economy, and speedometer accuracy, among other important benefits and drawbacks of upgrading tires on trucks and SUVs.

Bigger Tires, Bigger Wheels, or Both?

It is always our suggestion at Tires Plus that you follow the tire selection and size guidelines provided by the vehicle manufacturer. Some motorists, however, like to slightly vary from their vehicle’s original tire and wheel size in order to improve performance or add a touch of flair to their ride.

Plus-Sizing

In addition to fitting larger wheels, plus-sizing entails putting low-profile tires with the same diameter as the original wheels – this has the advantage of not affecting the vehicle’s ground clearance or speedometer. A vehicle’s turning and handling characteristics can be improved in some situations by increasing the vehicle’s plus-sizing. However, in the majority of cases, this is entirely a matter of personal preference. Our skilled experts can assist you in determining whether or not your vehicle’s tires should be upgraded to a larger size.

Up-Sizing

Upsizing refers to departing from the manufacturer’s recommended tire size by mounting tires with a greater diameter on wheels that are the same size or larger in diameter than the original tires. Upsizing has an influence on the speedometer, which necessitates reprogramming the vehicle’s computer system. Additionally, bigger tires add weight to the wheel assembly, which can reduce fuel efficiency and put an extra strain on the motor and brakes, among other things. Upsized tires may also rub against the wheel well, brake calipers, or vehicle structure if they are not designed or placed appropriately, possibly wearing out any parts they come into contact with.

What Happens When You Put Bigger Tires on Your Car?

It is recommended to adhere to the tire selection and sizing recommendations provided by your vehicle’s manufacturer, since properly sized tires aid in the maintenance of optimal stability and performance. If you decide to change the size of your tires from their original specifications, make sure that the new tires meet or exceed the load-carrying capacity of your vehicle when properly inflated, and consider whether the taller tires will have an impact on any Advanced Driver Assistance Systems on your vehicle.

Putting larger tires on your car, SUV, crossover, or light truck raises the clearance of the vehicle, increasing body roll and load transfer, which can have a detrimental influence on the balance and speed of your vehicle.

Pros and Cons of Bigger Tires on TrucksSUVs

The additional space created between your car’s undercarriage and the ground is perhaps the most important advantage of bigger tires. This is especially crucial for off-roading aficionados who require the extra space to get through difficult terrain safely. Drivers will be able to see further both on and off the road if they have more clearance. Depending on your requirements, increasing tire size might include installing gigantic 40-inch tires capable of traversing rocks or just increasing the diameter of your tires by a few inches.

Con: Added CostsAdjustments

Upgrading the tires on your truck is more sophisticated than just putting larger tires on the wheels and calling it a day. There are several steps involved. In certain circumstances, you may need to replace your existing wheels with new ones that are suitable with your larger tires. If the tires you want are too large for your wheel well, you may have to install a lift or leveling kit to make room for them, which may interfere with your ability to get proper wheel alignment services in the future.

While new rims and raise kits are typically a desired and fashionable complement to larger tires, they also represent additional expenditures that must be taken into consideration when making your selection!

Apart from switching the TPMS to the new wheels and relearning the locations if necessary, there isn’t much more to do with the system.

Pro: Better Off-Road Performance

Some people feel that larger tires provide greater off-road performance because they provide more ground clearance than smaller tires. Finding all-terrain or maximum traction tires in the proper size for your truck or SUV, on the other hand, can improve the performance of your vehicle when traveling off the beaten road. Max traction tires have deeper and broader treads to handle uneven and sloppy terrain, and they are robust enough to travel wherever the trail takes you!

Con: Lower Fuel Economy

Some people assume that larger tires provide better off-road handling because they provide more ground clearance. Finding all-terrain or maximum traction tires in the proper size for your truck or SUV, on the other hand, can improve the performance of your vehicle when traveling off the beaten track.

Max traction tires have deeper and broader treads to handle uneven and loose terrain, and they are robust enough to travel anywhere the route may lead you to.

Pro: CustomizationCurb Appeal

Increased tire size, generally complemented by larger rims and improved suspension, is a common trend among truck drivers. While some individuals prefer the off-roading advantages that larger tires provide, for others, the appearance of large wheels is all about making a fashion statement. A simple approach to personalize the appearance and feel of your driving machine is to increase the size of your tires.

Con: Change in Handling

Naturally, the greater height provided by larger tires results in a higher center of gravity for the vehicle. The handling of your vehicle will be altered as a result of the increased body roll and load transfer. It’s possible that you’ll have reduced stability when braking and cornering in some situations, especially if you’re going at high speeds. Additional modifications to the ride height and alignment angles, as well as changes in specific alignment angles, may need recalibration of the Advanced Driver Assistance Systems.

Con: Potential Voided Warranty

Aside from aesthetic considerations, some manufacturers will expressly advise against increasing the tire sizes on your car. If you opt to change your vehicle’s suspension by adding larger tires and a lift kit, some manufactures will even void your vehicle’s warranty.

Do Bigger Tires Affect MPG?

The average miles per gallon that your vehicle gets will be reduced if you put larger tires on it (MPG). There are a variety of reasons why bigger tires reduce fuel efficiency. For starters, larger tires are often significantly heavier than smaller ones. The addition of a set of four large and heavy tires to your vehicle will result in a significant increase in weight. This additional weight might have a negative impact on your vehicle’s acceleration and cause it to consume more gasoline. It can also put additional strain on your brakes, making it more difficult to slow down the car.

This might reduce the aerodynamics of your vehicle and raise its fuel consumption.

Do Bigger Tires Affect the Speedometer?

The average miles per gallon your vehicle gets will decrease if you put larger tires on it (MPG). Many factors contribute to the reduced fuel efficiency of bigger tires. Larger tires are, first and foremost, significantly heavier. A set of four large and heavy tires can significantly increase the weight of your car. Due to the additional weight, your vehicle’s acceleration may be impaired, as well as its fuel consumption. When attempting to slow down the car, it might place additional strain on your brakes.

This might reduce the aerodynamic efficiency of your vehicle and raise its fuel consumption. Last but not least, as previously said, wider and more aggressive tires have a bigger contact patch with the road, which might result in increased rolling resistance when driving.

The Pros and Cons of Plus Sizing

Moreover, Plus Sizing is a very new phenomenon (I believe it began in the late 1980s or early 1990s). When I say recent, I’m referring to the 1950s and 1960s, when I was getting into automobiles and making them seem hip on the street. With Plus Sizing, the primary concept is to replace the stock wheel size with a bigger diameter wheel while maintaining the same diameter of the original tire and wheel combo. When you placed bigger diameter tires on your rod back in the day, up to and including the 1970s, the only thing that happened was that your speedometer read slower than you were actually traveling.

  • The speedometer reading, as well as the ABS braking system, the engine management system, and in rare cases, the suspension control system, will all be affected.
  • In order to ensure that the input from the wheel and tire combination is not altered, the diameter of the OEM combination must be maintained.
  • A straightforward definition is to start with the original wheel diameter and increase it by a factor of two.
  • from 14′′ to 15′′).
  • That’s a little out there for me, but to each his or her own.
  • It’s really tough to achieve an exact match, but if you’re within 5 percent of the exact match, you’ll be fine.

Now let’s discuss the Pro’s and Con’s of Plus Sizing.

The Advantages – First and foremost, being Plus Size will make you seem cool. The greater the diameter, the greater the cooling effect (at least some folks think so). The most significant advantage of Plus Sizing is the improved road handling it provides. The height of the tire side wall decreases when the diameter of the wheel is increased (but the overall diameter remains the same as originally). This has the effect of reducing tire wobble or roll while simultaneously increasing the stability or cornering abilities of your car or motorcycle.

  1. The Negatives – The loss of suspension is the first thing that springs to mind while thinking about this.
  2. The amount of road noise will also rise.
  3. In order to reach this result, I have relied on a hypothesis that states that the larger the wheel, the more time it takes to maintain it sparkling.
  4. When it comes purchasing plus size clothing, there are a few things to keep in mind.
  5. Some wheel producers handle the problem by adding material to the wheel in order for it to meet the performance criteria set by the industry (see TECH Stuff 3).

The tire and wheel are considered unsprung weight, and their combined weight can cause excessive wear on the struts or shocks, bearings, spindles, and braking systems, among other components of the vehicle. Plus, when done correctly, sizing is not a negative trait.

Plus Sizing for Tires

What Are the Advantages? Being Plus Size will make you look and feel great. Cooler you are if your diameter is more than a certain size (at least some folks think so). In terms of road handling, the most significant advantage of Plus Sizing is the enhanced traction. The height of the tire side wall decreases when the diameter of the wheel is increased (but the overall diameter remains constant). This has the effect of reducing tire wobble or roll while simultaneously increasing the stability or cornering abilities of your car or truck.

  • There are certain disadvantages to this approach.
  • The effect of road bumps, potholes, expansion joints, and all of the other deformities on our roads and highways will be exacerbated if the sidewall of the tire is lowered or eliminated.
  • Additionally, you will feel a reduction in free time in addition to a reduction in riding comfort.
  • The fact that the tire mounting personnel who must mount these tires on the wheels (20′′ and higher) aren’t very enthusiastic about the whole notion is yet another disadvantage.
  • The wider the diameter of the wheel, the more difficult it is to achieve the load requirements for a wheel that is both safe and dependable in its application.
  • The weight of the wheel increases as more material is added, and the weight of the wheel grows greater than the suspension that the vehicle is built to withstand while still operating effectively.
  • Plus, when done correctly, sizing is not a terrible thing.
  • A sporty, stylish appearance
  • Improved performance, stability, and handling
  • And a longer service life.

Negatives of Plus Sizing include:

  • On icy roads, there is poor traction
  • The tire and wheel combination will be significantly heavier, particularly for SUVs and trucks that opt for the largest feasible plus sizes. This can result in longer stopping distances, worse gas consumption, and faster brake wear.

Plus, the following information about sizing:

  • Plus Zero – You merely alter the width of your tires
  • There is no increase in the diameter of your wheels. The wheel diameter is increased by one inch as a result of the plus one. The wheel diameter is increased by two inches as a result of the plus two. Plus Three — To achieve the maximum suggested wheel diameter, you should expand the wheel diameter by three inches.

The majority of the performance advantages received by using Plus Sizing Tires are obtained by using Plus One. As you rise in size, the good effects only marginally increase, while the unfavorable consequences may become more pronounced. It is usually suggested that you keep your tires’ diameter and height within 3 percent of the original equipment (OE) tires on your car. Further increases might result in brake failure, erroneous odometer readings, and other catastrophic issues.

Larger tires and plus sizing

It is the newest rage to have your car equipped with bigger tires and wheels.

They are visually appealing, but if they are not installed properly, you may be setting yourself up for some significant and quite expensive repairs.

Installing larger tires is called Plus Sizing

For example, a ‘Plus 0’ tire has the same diameter as the original equipment tire but has a wider tread area or a higher sidewall ratio than the original equipment tire. A ‘Plus One’ size tire is one that is 1′ bigger in diameter than the original equipment tire. Plus Two is a tire that is 2′ bigger in diameter than the original equipment tires. You can also install a Minus Sizing tire, which has a smaller diameter than the original equipment tire. When fitting new wheels and winter tires, minus sizing is occasionally employed since the smaller wheels are a little cheaper and the minus size results in additional sidewall height.

There are pros and cons to larger tires

For example, a ‘Plus 0’ tire has the same diameter as the original equipment tire but has a wider tread area or a higher sidewall ratio than the factory tire. One inch wider in diameter than the original equipment (OE) tire is known as a ‘Plus One.’ In comparison to the original equipment tires, the Plus Two tire has a 2′ wider diameter. You can also use a Minus Sizing tire, which has a smaller diameter than the original equipment tire. When fitting new wheels and winter tires, minus sizing is frequently employed since the smaller wheels are slightly less expensive and the minus size results in increased sidewall height.

Cons of plus-sizing tires — The downside of installing larger tires

When you put on wider tires, your acceleration and braking will be reduced, and your ride quality will be diminished. The greater tire diameter had an effect on the physics of acceleration and braking leverage. When the plus size is increased, the ride quality degrades, and the car begins to feel more like an off-road vehicle. It’ll rattle your head and knock out your fillings in a matter of seconds. Larger tires and wheels alter the suspension geometry, making it more difficult to control the vehicle.

  1. The addition of a lift kit has a considerable impact on the suspension geometry of the vehicle.
  2. If you’ve only installed a lift kit and haven’t changed the steering knuckle, brakes, axle shafts, wheel bearing size, strut, or stabilizer bar, you should expect to see a decrease in performance.
  3. CV joint wear and failure occur at a faster pace.
  4. The greater aerodynamic lift negates all of the benefits of the increased rubber contact with the road, resulting in a lower ability to stop.

Tire pressure for plus sized tires

When you switch to a larger tire, you almost always end up with a tire with a different maximum load rating, which means you have to utilize a different tire inflation pressure as a result of the change.

In order to determine the appropriate tire inflation pressure for your tires, use this chart. The year 2020 is a leap year. Rick Muscoplat is a professional musician. Rick Muscoplat posted a blog entry on

Guide to Plus Sizing Tires & Wheels

Plus size tires and wheels are available in a variety of performance and cosmetic options. It is possible to have a subtle or dramatic impact on the curb appeal of your car by altering its profile. It is also possible to boost performance while also enhancing cornering ability and shortening stopping distance by expanding the width of the tire while simultaneously generating a shorter sidewall, as seen in the image below. Plus size has gained in favor in recent years, but the technique has been present since the 1970s, when automotive fitments were either +1 or +2, enabling drivers to extend their wheel diameter by one or two inches.

Plus Sizing TiresIts Effect on Your Vehicle

Wheel sizes are now the dominant trend, by a significant margin. And, of course, with more demand comes an increased supply of tires that are designed to fit on larger rims. Landing clearance, wheel well space, speedometer readings, traction, stopping distance, driving line, and turning radius are all impacted by plus size, as are other aspects of the vehicle. To say nothing of the fact that it can cause problems with advanced driver assistance systems (ADAS) such as anti-lock brakes, traction control, adaptive cruise control, and other features, As a result, think carefully about the advantages and disadvantages of making significant changes to the tire and wheel size of your vehicle.

How Is Plus Sizing Tires Done?

Plus sizing is accomplished by selecting tire sizes and load capabilities that are similar to those of your original equipment—for example, by matching lower profile tires with bigger diameter wheels. In this manner, your vehicle’s speed and load rating will still match the specifications established by the manufacturer of your vehicle. For every inch that the wheel diameter is increased, the tire’s width must be increased and the sidewall height of the tire must be decreased. The rule of thumb is that for every inch increase in wheel diameter, tire width should be increased by 10 mm and sidewall height should be decreased by 5 to 10%.

The Pros and Cons of Plus Sizing Tires

Wider tires have a number of advantages, including shorter stopping distances, improved acceleration, and improved steering responsiveness. Cost, stronger sidewalls (which results in a more rigid ride), and lower profile tires being more susceptible to damage from road hazards such as potholes are some of the negatives of this option. Furthermore, every increase in handling often yields declining benefits beyond what is obtained by a +1 boost in performance. However, for those who appreciate the appearance and performance, this is a modest price to pay.

If you’re having it done by a local shop or vehicle dealership, make sure to specify that an expert tire installer completes the service.

You’ll want a guarantee of service that covers any damage to your car that may occur as a result of the repair being performed. It’s important to note that the more severe your plus size is, the greater the danger you face in terms of wear and strain on parts and reduced tread life.

Plus sizing – Wikipedia

A practice known as plus sizing is the replacement of an automotive wheel with one that is larger in diameter and fitted with a new tire that has a lower aspect ratio so that the new tire has a diameter and circumference that are close in size to the original tire in order to minimize any changes in speedometer accuracy, torque, and traction control, while reducing sidewall flex and (generally) increasing cornering ability.

See also:  Should you buy an extended warranty? (Perfect answer)

The number that appears after the ‘plus’ represents the number of inches that have been added to the circumference of the rim.

A ‘plus zero’ upgrade entails upgrading to a larger tire size while keeping the same diameter wheel as the original.

When it comes to tire sidewall height, the aspect ratio is a percentage that is used to calculate the height of the tire’s sidewall.

Plus sizing example

Original tire Plus zero Plus one Plus two
205/60R16 215/55R16 215/50R17 235/40R18

These are only samples, and they do not reflect all of the conceivable combinations that may lead to the same conclusion as the ones shown here. 195/65, 205/60, 215/55, 225/55, 235/50, 245/50, 255/45, 265/45, 275/45, and 285/40 are the tire sizes available for an R16 tire. Tires with a high width-to-aspect ratio have virtually the same diameter as other tires. Tires of the same size may have somewhat different precise dimensions depending on the tire manufacturer, model, and other factors.

Advantages

  • Because of broader tread faces and stronger sidewalls, larger tires provide better handling and cornering performance. On dry pavement, wider tires may help to reduce braking distances. The use of wider tires may also help to improve acceleration, particularly in high-performance vehicles such as muscle cars. Larger wheels with lower profile tires might be aesthetically pleasing in some situations.

Disadvantages

  • Larger wheels are often more expensive. Wider tires are more expensive than narrower tires since they are less frequent and there is less rivalry amongst manufacturers. Improvements in performance over and above what is obtained in a Plus One size are frequently insignificant. Lower profile tires tend to have stiffer sidewalls, which may reduce riding comfort
  • Low profile tires are more likely to sustain more damage to their tires and wheel rims when they come into contact with road debris and potholes
  • Low profile tires are more likely to be damaged by road debris and potholes. Larger and broader wheels reduce fuel economy while simultaneously increasing consumption and pollution. Larger and wider wheels may also reduce acceleration on many everyday vehicles, according to a test carried out on a Volkswagen Golf 2.5, which saw a 10% decrease in fuel efficiency from 23.3 to 21.1 U.S. miles per gallon (from 10.1 to 11.2 liters per 100 km) when converted to a Plus Four configuration. According to the results of the test on a Volkswagen Golf 2.5, the acceleration from zero to sixty miles per hour (0 to 97 kilometers per hour) decreased by 0.3 second, from 7.6 to 7.9 seconds in a Plus Four size. Even though it is most likely caused by the 14 lb (6.4 kg) weight differential in ‘unsprung weight’ per corner, a bigger tire-footprint may lengthen the time required to ‘return to center’ (steering) after taking a fast turn.

Controversial issues

Some individuals believe that bigger wheels wear out more quickly. It is possible that wheels with lower sidewall heights will increase the likelihood of rim damage, breaking of the bead, and/or damaged sidewalls. Greater hydroplaning risk is associated with larger tires because of the increased breadth of the contact patch. The addition of larger tires to a vehicle may increase its resale value. It is possible to raise the value of a vehicle by making modifications to it from its manufacturer specs.

Reduced sidewall height during fast tire deflation at high speeds may help to lessen the risk of rollovers.

Oversized rims and tyres have a greater tendency to produce unsprung weight than standard fit wheels and tyres.

As a result of the decreased inertia, the shock absorbers and dampers are considerably better able to regulate the vertical ‘bounce’ of a wheel over a bumpy road surface. This results in smoother and more constant contact between the tyre and the road surface.

References

Tires are one of the most important components of a vehicle, yet they are frequently overlooked. Tires are rarely discussed on automobile forums or in discussions among car enthusiasts, and when they are, it is usually during the process of replacing out the rims. The most often seen exchange is an upsizing. The word refers to the installation of larger wheels and suitable tires on a vehicle. From then, things have taken a number of different paths throughout the years, with some tuning trends including doing terrible things to tires.

  1. While the aesthetic issue comes to mind, such stretched tires may appear attractive in photographs and movies, but they are detrimental to the ride, handling, and safety of the vehicle.
  2. In the event that this diameter is not maintained, the tire may come into contact with the edges of the fenders during strong cornering or other circumstances, as well as with other components of the vehicle’s mechanical system.
  3. Not only is it difficult to locate suitable tires, but it is also difficult to accept the reduction in comfort that comes with tires with exceptionally low profiles.
  4. A tire calculator is available on the Tirerack website, as well as on other comparable websites, for your convenience.
  5. Theoretically, increasing your contact patch with the road will benefit you if you use larger tires.
  6. The fact is that new wheels and tires only provide a small boost in grip, and in most cases, this is due to the buyer selecting better-performing tires for their vehicle.
  7. It is not always the case that bigger is better.

In addition, the bigger wheel would make your automobile appear cooler.

Low-profile tires mounted on bigger diameter wheels deceive the driver into feeling the automobile has more grip because of a quicker turn-in reaction, but in reality, it is the rubber’s composition that makes the true difference in real-world performance.

For starters, it has something to do with weight.

The more the unsprung mass, the greater the negative impact it has on the handling, performance, and dependability of the entire rolling gear system as a whole.

The use of larger wheels and tires does not improve performance; rather, it increases acceleration times and fuel consumption.

A drastic size increase will necessitate the use of smaller sidewalls for the new tires, resulting in diminished ride comfort and an unsatisfactory driving experience in general.

Another disadvantage is that the larger wheels and tires will be more expensive than their smaller-sized counterparts, which is another drawback.

This can become a problem since tires with short sidewalls are more susceptible to failure caused by road debris.

There are also concerns with the installation of bigger wheels and tires.

If you upgrade to a larger or smaller size, you run the risk of changing the handling of your car.

In addition, if you make drastic modifications to your wheel and tire sizes, your suspension bushings may be impacted by your new wheel and tire combination.

Do you remember the unsprung weight incident?

The braking system will have a more difficult job ahead of it, and the wear on the pads and discs will accelerate.

Numerous experiments have shown that the time from zero to sixty-two miles per hour (zero to one hundred kilometers per hour) may be reduced by up to four percent.

First and foremost, you must research the regulations in your state to see what modifications you are permitted to make to your wheels and tires.

Second, pay attention to the wheel and tire combinations (as well as their sizes) that the manufacturer of your vehicle offered as optional equipment when your model was first introduced to the market.

You should opt for lighter aftermarket rims and high-performance tires if you want to experience a gain in performance as a result of upgrading to larger wheels and tires.

Avoid purchasing knock-offs since they will not match the weight, performance, and durability of wheels produced by genuine manufacturers.

If you make the appropriate selections, the combination of lighter wheels and high-performance tires should result in a little increase in performance.

If you do, the handling, fuel economy, and overall performance of the vehicle will be compromised.

For example, tire professionals recommend that the tire diameter be changed no more than +/-3 percent from its original size.

It is possible that you will receive some free advise even if you do not purchase any components from them; however, you must ask gently and considerately and not push your luck on the free information front.

The most detrimental aspect of using unusual wheel and tire combinations is that they will wear out more frequently, even if everything else on your vehicle is in working order.

Can I Change the Size of My Tires?

So you’re thinking of changing the size of your tires to accommodate a new vehicle. Before you go, you should be aware that changing the tire size of your car has a greater influence on it than simply changing its appearance. Plus-sizing your vehicle’s wheels and tires, also known as ‘oversizing,’ can have a negative impact on its accuracy, handling, steering reaction, and other aspects of the vehicle’s performance. Changing the tire size may be dangerous if done wrong, since it might compromise the overall safety of your car.

  1. Tires that are taller Consequently, you have decided that you want to go with the huge tire appearance.
  2. Increased tire height can aid in the reduction of fender well gap, the enhancement of ground clearance, and even the provision of a smoother ride for some vehicles.
  3. The majority of trucks, SUVs, and crossover vehicles, on the other hand, have sufficient clearance to accommodate a larger tire size if necessary.
  4. Larger tires can have a detrimental impact on stopping power as well as on pavement comfort, since the increased unsprung weight might result in a harsher ride on the road.
  5. ‘Plus-zero’ sizing refers to the practice of using a larger size while preserving the same overall diameter.
  6. Trucks, SUVs, and crossover vehicles can all benefit from this sort of modification in tire size as well.
  7. They can also significantly shorten turning radius since larger tires make contact with bump stops earlier.
  8. Remember that changing the size of your tires has both advantages and disadvantages, and that you should weigh them carefully before making your decision.

Right Sizing: How To Properly Select A Larger Tire Size

Changing the tires on a vehicle is one of the simplest and most effective modifications that an automobile enthusiast can make to alter the appearance and customize their vehicle. In this video, I learn how to select the suitable size tire for the car with the aid ofToyo Tires, which is not always easy when you’ve already decided not to remain with the original size. There are a number of questions that must be answered before you can be guided to the most appropriate tire for your application.

This will assist you in determining if you need a highway tire, an all-terrain tire, a hybrid tire, or a mud terrain tire.

Choosing a tire for a new car may be a stressful scenario, but with the assistance of Toyo Tires’ Right Sizing, that decision has just became a little bit simpler.

I got the opportunity to chat with Todd Bergeson, light truck tire product manager at Toyo Tire USA Corp., in order to have a better knowledge of how to choose the best tire for my needs.

According to Bergeson, ‘Toyo has been working hard to develop feasible solutions that will let consumers to obtain the style, size, and performance they desire while using a tire that is adequately load rated for their vehicle.’ ‘Right Sizing,’ as we call it, refers to Toyo manufacturing a tire that is tailored for the use for which it is intended.’ Toyota is now offering ‘Right Sized’ tire alternatives in the Open Country A/T II all-terrain tire for a variety of SUVs, trucks, and soft-roaders, such as the overlanding sector, that are well suited for this type of application.’ The wheels and tires that came with the vehicle were not going to cut it for this use.

So I went out and bought a new, bigger tire for our 2019 Chevrolet Silverado to put this theory to the test.

For me, it was important that the vehicle be clean and functioning because it would be spending a lot of time in the dirt, as well as on the road and in everyday life.

We recently purchased a new truck, and the last thing I want to do is compromise the fantastic riding qualities of the vehicle in order to attain a rougher, more individualized appearance.

I didn’t want to make a sacrifice on the ride or the loudness in order to have a closer view. Toyo Tires, fortunately for us, employs advanced computer design tools and simulators to generate tread patterns that are both quiet and aggressive in appearance.

LT vs. P-Metric

It is the responsibility of the Tire and Rim Association Inc. to develop technical standards on behalf of the tire and rim manufacturers in the United States. Simply explained, the terms LT and P-Metric relate to the sort of tire servicing being provided. The letters LT and P signify tires that are primarily designed for use on light trucks, with P denoting tires that are primarily intended for use on passenger cars. In addition, ‘it is critical to understand that there are some substantial changes in tire structure and inflation pressure requirements between LT and P-Metric tires,’ Bergeson explained.

  1. According to Bergeson, there are a variety of reasons why a manufacturer would chose the P-metric tire for what we consider to be a light-truck application.
  2. It will be easier to ride in compliance if the required pressure is reduced.
  3. ‘The P-Metric tire that is installed as standard equipment on current pickup trucks and/or SUVs is designed particularly for those vehicles.
  4. A different type of tire, called an LT tire, is designed for more harsh situations and greater loads.
  5. It is the responsibility of the Tire and Rim Association (TRA), of which Toyo Tires is a member, to develop tire and rim load and inflation criteria for both low and high pressure tires.
  6. This was necessary due to the fact that a number of tire manufacturers at the time, and some still do today, only produce these tires in LT-metric.
  7. These cars are all of unibody design, with suspension components that are quite modest in weight.

Thanks to Toyo Tires’ Open Country collection, these SUVs and crossovers may now be outfitted with tires that are more suited for their size, whether that be in P-metric or Euro-metric.

‘Staying with a P-Metric on a 1/2-ton chassis or smaller allows you to maintain the OE ‘placard’ air pressure that has been specified by the vehicle manufacturer to meet its certified load-carrying capability,’ Bergeson explained.

‘ If you increase the size or alter the metric standard, the ride and driving qualities will change.’ ‘When compared to the installation of an LT fitting on that chassis, the ride quality of your 1/2-ton truck will be greatly improved with a P-Metric or Metric tire,’ Bergeson stated.

When attempting to identify the suitable tire for your application, always refer to the placard and/or owner’s handbook that came with your vehicle.

LT-metric tires may be mounted on chassis that are 1/2 ton or less in weight, but the ride quality will normally worsen, the wear and tear on the suspension elements will rise, and the additional weight will impact how responsive the vehicle is, according to Bergeson.

Another significant distinction between LT and P-Metric tires is how much of a financial impact they will take.

The P-metric tire has a cheaper cost than the LT tire of the same size since it is made of plastic. Choosing a P-Metric tire over a non-P-Metric tire may make more sense and result in extra cost savings.

Plus Sizing And How It Affects Your Vehicle

The experience of trying to put the widest possible tire on your vehicle, getting everything mounted, going to spin the wheel and ending up back under the truck trimming and cutting away to make it clear is one that everyone has had. I made the decision that I was not prepared to compromise on anything on my brand new, gorgeous 2019 Silverado, but I did want a bigger tire for the truck. Using Toyo’s Find Tires area on their website, I was able to establish which plus size would be the best fit for my truck and which size would be the worst fit.

Plus Sizing

Plus Zero: When the diameter of the wheel remains constant but the width is raised, the wheel is referred to as ‘Plus Zero.’

  • Increase the section width and reduce the aspect ratio while keeping the wheel diameter the same or lower. This replacement tire has a larger contact area and a lower tread profile, which results in increased grip and faster reaction.

Plus One: If the wheel size is extended by one inch, it is referred to as a ‘Plus One’ modification. Tires with a greater section width and a lower aspect ratio are mounted on wheels with a bigger diameter when this size is used. Originally equipped with 16-inch wheels, a Plus One setup for a car would utilize 17-inch wheels as an alternative. As a general rule of thumb, Plus One size should be as follows:

  • Increases section width by 10 mm
  • Decreases aspect ratio by 10 points
  • Increases rim diameter by 1 inch
  • Increases section width by 10 mm

Additionally, the wheel size is enlarged by two inches, which is referred to as ‘Plus Two.’ Using the example above, a Plus Two fitting for an automobile equipped with 16-inch original equipment wheels and tires would be 18-inch wheels and tires. Plus Two Sizing: A typical rule of thumb is as follows:

  • It widens the section by 20 mm and reduces the aspect ratio by 20 points, while also increasing the rim diameter by 2 inches.

Additionally, the wheel size is enlarged by three inches, which is referred to as ‘Plus Three.’ Example: A Plus Three fitting for a car with original equipment wheels and tires that are 16 inches in diameter is a set of 19-inch wheels and tires. The following is a basic rule of thumb for Plus Three Sizing:

  • It widens the section by 30 mm and reduces the aspect ratio by 30 points, while also increasing the rim diameter by 3 inches.

The Find Tires feature on Toyo’s website allows users to search for a specific truck by make, model, and even trim to find out what was initially designated as an OE size for that chassis, according to Bergeson. ‘A Plus Zero reference indicates that a bigger size tire is available to adequately fit the truck’s original equipment wheel. As a result, a somewhat bigger footprint and/or diameter can be accommodated while still maintaining within the parameters of the vehicle.’ Continuing, Bergeson said that ‘in other situations, Toyo uses the phrase ‘Right Sizing’ to designate a tire that was made precisely to fit an original equipment wheel, but that was also designed to better fill the fender openings while giving it a more aggressive appearance and feel.’ The Open Country A/T II comes in a P285/55R20 114T size, which is an example of this.

  1. It is exclusively available from Toyo Tires, and it features an even more aggressive shoulder and sidewall design.
  2. In order to rectify the factory rake of the Silverado, we added Baja Kit’s leveling kit.
  3. ‘When providing replacement tire suggestions, the tire finder on our website takes into consideration your vehicle’s original equipment tire size as well as its maximum load capability at placard pressure,’ Bergeson explained.
  4. It is possible to find sizes up to Plus Three or larger while still keeping an outer diameter that is suitably sized for the OE wheel well and/or chassis height,’ says the manufacturer.
  5. The leveling system from Baja Kits was placed below the factory strut assembly, and I was able to remove the factory rake in less than an hour.
  6. The fact that this is so widespread in the light-truck industry is one of the reasons why ‘leveling’ kits are so popular.
  7. Therefore, an excessively big tire, such as a 40-inch tire, would not be included in those size guidelines since the vehicle would have to be elevated in order to fit the larger outer diameter.

If you are a custom builder, there is an expanded chart in each individual tire area on the website that offers all tire dimensions, weights, load and speed ratings so that you can evaluate which tires are the best match for your needs.

Making The Decision

I chose our tire because I had all of the information I needed. I chose an LT285/75R17 Open Country M/T tire, which is around 34 inches in diameter and 11.5 inches in height. The choice to go with this size was made based on the information supplied by Toyo as well as an image in my head of how I wanted the vehicle to appear in the end. I drove to the Woodcrest Ramona Tirelocation with the new wheels and tires in tow in order to have the Open Country M/Ts mounted and installed on the vehicle.

  • The expert at Ramona Tire worked quickly and efficiently to put the tires to the wheels, and before I knew it, the tires were mounted to the wheels of the vehicle.
  • When installing a leveling kit and brand new tires, or whenever the suspension of a vehicle is altered, it is important to have the car’s alignment checked.
  • I couldn’t be happier with my selection for the vehicle in the end because it turned out precisely way I wanted it to the first time, with no rubbing or other problems.
  • The truck’s ride quality is still as good as it was when I drove it off the lot, and I can still slip into those tight parking garages with low ceilings.

Larger Tires and Wheels on Your Vehicle? Postle Tire Barn

Is it feasible to upgrade your vehicle’s tires and wheels to a greater size? The majority of the time, the answer is yes. No one can disagree that having larger tires and wheels on your vehicle, light truck, or SUV adds to its overall visual appeal. ‘Plus sizing’ refers to the process of fitting a bigger tire and wheel combination to your vehicle, such as a ‘plus one’ or ‘plus two’ fitment, to your vehicle.

Plus One and Plus Two Fitments

‘Plus one’ indicates that you are increasing the diameter of your wheels/tires by one inch, and ‘plus two’ indicates that you are increasing the diameter by two inches. Going for a ‘plus two’ fitting means that you are replacing your 15-inch tires and wheels with 18-inch tires and wheels if you have a vehicle that has 16-inch tires and wheels. What method will you use to do this? The plus-size idea operates on the following essential principles: As the diameter of the wheel increases, the size of the tire’s sidewall must decrease in order to retain the overall diameter of the tire.

For a variety of reasons, maintaining a consistent overall tire diameter is critical to maintaining the same gear ratios and accuracy of the speedometer, as well as ensuring that the wheels and tires are able to fit within their respective fenders.

Things to Consider

In general, bigger wheels weigh more, and the added weight may have an effect on performance as well. According to testing data, when wheel-and-tire packages grow in size and weight, your ability to accelerate declines, and your fuel efficiency falls as a consequence. There are a number of things to take into consideration. The first question is whether or not the new tirewheel fitting will clear your fender wells. There are rarely any clearance concerns with the rear tires and wheels, although there are a few instances where they do occur (see next paragraph).

It is necessary to consider how far your vehicle ‘bounces’ when traveling over difficult terrain, such as off-road or even potholes, when designing applications for the rear.

when the vehicle bounces up and down on the road.

In some cases, such as when replacing a 15-inch street tire with an extremely big (and tall) off-road tire, this can occur.

So the Answer is…

Is it possible to put larger tires and wheels on my vehicle? That is the answer to the question. is, for the most part, affirmative. It is true that there are some factors and scenarios that will limit how much larger of a tire and wheel application can be put on a vehicle, but in general, larger tires and wheels may be fitted on virtually any vehicle. There will always be some exceptions to the rule. For example, if you have a car that is equipped with high-performance tires that are of different sizes on the front and rear wheels.

A tire and wheel specialist, such as those at Postle Tire Barn, is the ideal person to talk with for the best response.

For more than 35 years, Postle Tire Barn has been fitting tires and wheels, including plus size, on a variety of vehicles.
