Enter your tyre width, aspect ratio, and rim diameter into the calculator to determine your motorcycle tyre size.
Tyre Size Calculation Formula
The following formula is used to calculate the overall diameter of your motorcycle tyre.
Overall Diameter = (Tyre Width * Aspect Ratio / 100 * 2) + (Rim Diameter * 25.4)
Variables:
- Overall Diameter is the total diameter of the tyre (mm)
- Tyre Width is the width of the tyre (mm)
- Aspect Ratio is the height of the tyre sidewall as a percentage of the width (%)
- Rim Diameter is the diameter of the rim (inches)
To calculate the overall diameter, multiply the tyre width by the aspect ratio divided by 100, then multiply by 2. Add this to the rim diameter multiplied by 25.4 to convert inches to millimeters.
