Tire Aspect Ratio Calculator

Formula

The formula to calculate the Tire Aspect Ratio is:

$TAR = \frac{SH}{W}$

Where:

TAR is the Tire Aspect Ratio
SH is the tire sidewall height
W is the tire width

Tire Aspect Ratio Definition

The Tire Aspect Ratio is the ratio of the tire's sidewall height to its width. It is an important parameter in determining the overall performance and handling characteristics of a tire. A lower aspect ratio typically indicates a sportier tire with better handling, while a higher aspect ratio indicates a more comfortable ride.

Example Calculation

Example:

Sidewall Height (SH): 5 inches
Tire Width (W): 10 inches

Step 1: Calculate the Tire Aspect Ratio:

$TAR = \frac{5}{10} = 0.5$
