Tire Size Calculator - The right place to pick your vehicle's tire with exact dimensions
Which size tire should I buy for my car?
Drivers often ask this question regarding tire sizes. Most vehicles can accept various sizes if certain parameters are met. For a list of possible alternatives and alternatives to your current tire size, you can use the handy tire size calculator. Just enter your current tire size.
You must consider your car model and make when using the tire size calculator. Many drivers prefer to stay within the same size and diameter when choosing a new tire. These tires are called equivalents, while alternatives are usually larger. Upgrading this way is called plus sizing.
What is the acceptable tire size?
Our tool tells you how much the outer diameter of a tire differs when using a tire size comparison tool. In this case, a positive number means the tire is larger/wider, while a negative number indicates a negative change. The recommended range for these results is between 1.5% and 2%.
Which tire size is right for you?
Most drivers change their tire size to improve or achieve certain driving parameters on their vehicles, not because they need to. You should be aware of the benefits and drawbacks of alternative sizes, including shorter braking distances and drawbacks, so you should decide what you want from your car tires.
What is Tyre upsizing?
Getting a bolder look and better road grip can be achieved by installing wider tires in your car. It is also possible to upsize your car's tires by installing larger wheels (alloy wheels) and a wider tire. Regardless of the method used, the result will be the same, a sporty look and improved handling capabilities. If you consider upgrading your car's tires, you may wonder how they will improve your handling. Wider tires give a wider contact patch to the road surface. As a result, the vehicle feels more stable on the road at high speeds and corners since the weight is distributed more efficiently. The following sections cover the various factors that may be affected if the tire size needs to be calculated correctly. When installing tires of different sizes on your vehicle, our tire size calculator will help you estimate the differences in dimensions, clearance, revolutions per mile, and other characteristics. With this calculator, you can find out how much each tire differs from another in inches, centimeters, and percentages.
Tire Size Calculator
This calculator automatically calculates the estimated circumference in both mm (as used by most new cycle computers) and cm (as used by some cycle computers) based on selecting the wheel and tire sizes from the table and entering their sizes in mm. specifies the tire size as a width and rim circumference in mm, based on ISO/ETRTO (European Tyre and Rim Technical Organization) specifications. The ISO tire size 28-622 corresponds to a 700 x 28C tire with an internal diameter of 622 mm and a width of 28 mm. You can enter your wheel's diameter (mm) if the size is not listed in the drop-down menu.
If you want to know how big your tire is, type in size and click the calculate button. You can type in a metric or standard-size tire and click the calculate button. You can read inch tires easily, but you must get used to metric tires. A metric tire's width is its first number. Divide it by 25.4 to get the inch equivalent. The wheel diameter is usually preceded by an "R" on a tire. As a result, metric-sized tires are measured by their sidewall and aspect ratio to determine their overall height. The sidewall height is calculated from the second number on a metric tire. This second number represents the proportion of the width of the tire. An aspect ratio of 75% represents the sidewall height of a 285/75/R16 tire.
We make this easy for you with the tire calculator. Enter the metric measurements in the fields, and click convert to inches. Moreover, it helps you decide what tire to run if you know inch measurements but need help locating a manufacturer that manufactures a tire of that size. It calculates the exact metric version of that tire by filling in the inch measurements. A tire size calculator is helpful in metric tires since there are more possibilities and choices. Calculate the diameter, width, sidewall, circumference, and revolutions per mile of two tires with the tire size comparison calculator. It also shows how fast you travel if you install the second tire and how fast the speedometer reads with the first tire. It's a great tool for finding tires of different sizes from stock. The tire suggestion guide sets us apart from the rest. You can get the answers you need with a tire size conversion calculator or a tire diameter calculator. tire calculator suggests a variety of tire sizes that are within an inch of what you entered. We'll help you find the right tire with no fuss.
What is the purpose of the tire calculator?
A tire's size will be displayed on the top row. You can easily find these measurements on the sidewalls of your tires. Choose the width of the tire in inches in the first box. Select the ratio of height and width in percentages in the second box. Specify the disc diameter in inches in the third field. You must specify the size of the new tires in the second row or the size you purchase. Upon entering all the parameters, click the green "Calculate" button. You can select metric system (cm) or inch measurements by clicking the switch. A calculator for tire size comparison displays the difference in size between the tires instantly in a table. The final recommendation can be in green or red, depending on the tire size difference. If a difference in diameter is greater than 3% from your current tires, the result will be red. We strongly advise against using tires that differ in size by more than 3% from your existing tires since driving with these tires can be dangerous.
The size of your car's tires plays an important role in its optimum performance, so you will need tire size calculators if you wish to upgrade them. If your tire size is correct, your vehicle will perform well and produce less fuel efficiency, which is something you want to avoid. For this reason, you must thoroughly understand tire upsize calculation before you embark on this type of modification. During tire/wheel modifications, you should follow a few basic rules.
Keeping the original wheels and alloys
Tyres that are upsized with the original wheels, however, will not have the metal components, such as alloys or rims, modified, but the tire will be changed according to fitment guidelines and possibilities. To ensure safe tire upsizing, you must maintain a 3% tolerance for the OD (overall diameter) of the new tires compared to the stock tires' OD. The permissible tolerance can be achieved in the following way.
Retaining the original wheels while upgrading to wider tires
These modifications only involve changing the rubber tires. The metal wheels do not have to be manipulated. You can install larger tires according to your requirements and compatibility possibilities. It is always safe to swap tires within the acceptable limits - that is, less than 3 percent of the original diameter of the stock tire.
A larger wheel/alloy wheel upgrade
Changing the wheels the manufacturer provides is part of this type of modification. By upgrading to larger wheels, the car's overall appearance is enhanced. As the tire sidewall height is on the lower side, tires for larger wheels are generally called low-profile tires. Tires are fitted according to requirements or the space between wheel arches and the wheel rims. 205/55 R16 would be the new tire size for the 16-inch wheel. The original diameter must be between 24.47 and 25.20 inches or within the permitted limits.
A larger set of wheels/alloys
When you talk about upsizing your car tires, you are modifying the company-fitted wheels to increase their diameter and appearance, thereby upgrading to larger wheels or alloys. As a result, these increased-diameter alloy wheels are fitted with low-profile tires by the possibility of a gap between the wheels and the wheel arcs of the vehicle. It would be best to keep the OD within 3% tolerance, i.e., 24.47 - 25.20 inches, before upgrading to a 16-inch alloy wheel.
The benefits of tire upsizing
A wider set of tires has several advantages over stock tires on your vehicle.
- With wider tires, the vehicle feels planted on the road when cornering or running at high speeds since the weight distribution is more efficient. As we mentioned earlier, wider tires improve road grip. When driving at high speeds, wider tires give you more confidence and control over your vehicle.
- The vehicle's enhanced stability or overall balance is a significant benefit of tire upgrading. A wider tire increases the contact patch, and a wider contact patch increases the stability and handling of the vehicle. Lower sidewalls and wider contact patch lead to better handling.
- Feeling confident about your vehicle's brakes to drive safely would be best. Wider tires grip the road surface better than stock tires, so the braking distance is shorter. You can still control the vehicle when you brake hard due to the grippier tires. Therefore, you can control your vehicle regardless of how hard you slam the brakes.
- A sporty appearance can be achieved by widening the tires and installing larger wheels. Various alloy wheel designs are available in the market, allowing you to tailor your vehicle to fit your needs.
- Upgrading your wheels to lighter wheels and upsizing them improves the handling and performance of your vehicle.
- You might get better mileage with the weight reduction, especially if you're constantly stuck in traffic.
Tyre upsizing's drawbacks
There are several disadvantages to upsizing vehicle tires.
- Using wider tires will make you have a lower fuel economy because they grip better on the road. You might get a better handling experience, but it'll hurt your fuel economy. Wondering how? The more grip there is, the more rolling resistance there will be, which means the engine has to work harder. The harder the engine works, the more fuel it needs; that chain reaction makes it harder to get a good fuel economy.
- The extra weight of wider tires/wheels can negatively affect vehicle handling and may result in a heavy steering feel.
- There's a reason you don't see low-profile tires on mass-market vehicles: Upsized tires tend to have a lower sidewall, resulting in a bumpy ride.
- Upsized tires can damage the wheel arches on your car: Upsized tyres appear attractive, but they can harm you when you drive over bumps or potholes.
An analysis of tire size comparison
It's a good idea to compare a specific range of tire sizes more accurately after using the tire size converter - or if you've already chosen some tire sizes. A tire size comparison tool is handy when comparing many tire sizes. Select your original size and then compare several others you're considering. The tire-size converter works for any car. Although manufacturers recommend certain tire sizes, you can always look for alternatives you'd like. As mentioned earlier, you can customize your driving experience through your vehicle's performance parameters, which have different benefits and drawbacks.
It is usually necessary to change both the diameter of the wheel and the tire to choose an alternative tire size. When you fit a smaller tire, the overall profile will automatically be lower than it was previously unless you use a wider wheel to compensate (this would require a tire with the same internal diameter). Furthermore, you should always be aware that various driving characteristics may change due to changing tire size, including fuel consumption and grip. It is important to consider the pros and cons of choosing a wider or narrower tire. Also, tire size changes should be at most 1.5% or -2%. Proper tire sizing can damage your car. Wider rims and tires will cause excessive wear and tear and more difficulty while driving. As a result, we recommend using a tire size comparison tool to ensure that the change is manageable, as it can damage additional car parts, such as the suspension system.
How does tire size affect ground clearance? If you increase the wheel size, the tire size will increase the ground clearance. Ground clearance is defined as the distance between the road surface and the car's lowest point. The increased ground clearance that occurs when you increase tire size and wheel size is one of the apparent outcomes. A significant increase in ground clearance cannot occur if you only upgrade your tire.
Transmission performance changes with tire size? The transmission is unaffected by changing tire size, but the wrong tire size affects the final drive ratio. For example, the final drive ratio will be low if the tires are too large. Similarly, too small tires will lead to a higher final drive ratio. The effect is very menial as you must go to extremes to modify your car before you can install too big or too small tires.
