How to Use the Wheel Size Calculator?

1. Enter the Tire Width

Start by inputting the tire width in millimeters. This is typically the first number in a tire size specification (e.g., in 205/55R16, 205 is the tire width).

2. Input the Aspect Ratio

Next, enter the aspect ratio, which is the tire’s height as a percentage of its width. This is usually the second number in the tire size (e.g., in 205/55R16, 55 is the aspect ratio).

3. Specify the Wheel Diameter

Enter the wheel diameter in inches. This is typically the last number in the tire size specification (e.g., in 205/55R16, 16 is the wheel diameter).

4. Click Calculate

After entering all the required information, click the “Calculate” button to process the data.

The calculator will display the following information:

• Sidewall Height: The height of the tire’s sidewall in millimeters.
• Overall Diameter: The total diameter of the wheel and tire combination in inches.
• Circumference: The distance around the entire wheel and tire in inches.
• Revolutions per Mile: How many times the wheel will rotate in one mile.

While the calculator provides accurate measurements, always ensure that any tire size you’re considering is compatible with your vehicle’s specifications and local regulations.

By using this Wheel Size Calculator, you can make informed decisions about tire and wheel combinations, ensuring optimal performance and safety for your vehicle. Whether you’re looking to upgrade your wheels for aesthetic reasons or seeking to fine-tune your vehicle’s performance, this tool provides valuable insights into the dimensional changes that come with different tire sizes.
