Calculation Formula

Tire Height (inches) = (Tire Width (mm) * Aspect Ratio / 100) / 25.4

Where:
Tire Width (mm): The width of the tire in millimeters.
Aspect Ratio (%): The ratio of the tire's cross-sectional height to its width, expressed as a percentage.
Rim Diameter (inches): The diameter of the wheel rim in inches.

How to Use the Calculator

  1. Enter the tire width in millimeters.
  2. Enter the aspect ratio percentage.
  3. Enter the rim diameter in inches.
  4. Click the "Calculate" button to see the tire height and overall diameter.

Understanding the Results

The tire height is the height of the tire's cross-section in inches. The overall diameter is the total diameter of the tire when mounted on the rim.

Example

If you have a tire with a width of 205 mm, an aspect ratio of 60%, and a rim diameter of 17 inches, the calculator will determine the tire height and overall diameter.
