Understanding Tire Sizes

Tire sizes are represented by a code that contains three main numbers:

Width

The first number represents the tire's width in millimeters from sidewall to sidewall.

Aspect Ratio

The second number is the aspect ratio, representing the tire's height as a percentage of its width.

Wheel Diameter

The last number indicates the wheel diameter in inches.

Example

A tire size of 265/70R17 means: 265mm wide, 70% aspect ratio, fits 17-inch wheel.
