How Is the Height of a Winter Tire Measured?
The height of a winter tire is measured from the ground to the top of the tread when the tire is mounted on a wheel and inflated to the recommended pressure. This measurement is referred to as the tire’s overall diameter. To obtain this, follow these steps:
- Understand the tire size designation. The size is typically indicated on the tire sidewall, such as P225/60R16.
- Break down the size designation. The first number (225) indicates the tire’s width in millimeters. The second number (60) represents the aspect ratio, which is the height of the sidewall as a percentage of the width.
- Calculate the sidewall height. Multiply the width (225 mm) by the aspect ratio (0.60). This results in a sidewall height of 135 mm.
- Convert the sidewall height to inches if necessary. Divide by 25.4 to convert millimeters to inches. The sidewall height in inches is approximately 5.31.
- Add the sidewall height to the diameter of the wheel. The standard wheel diameter is indicated by the last number in the size designation (16 inches). Thus, the calculation becomes 5.31 inches (sidewall height) × 2 + 16 inches (wheel diameter).
- The overall height of the tire is approximately 26.31 inches.
Therefore, when measuring the height of a winter tire, always consider the sidewall height and wheel diameter together.
What Is the Difference Between Tire Diameter and Overall Height?
