Locate Your Tyre Size Quickly

Your tyre size is listed on the sidewall of your tyres or in your vehicle's manual. It is presented as an alphanumeric list, with each number or letter representing a specific dimension of the tyre.

Here's what some of these numbers and letters mean:

(225) TYRE WIDTH:This number measures the tyre's width from one sidewall to another in millimeters. For instance, a 225/45 R17 tyre is 225 mm wide.

(45) ASPECT RATIO:This is the number following the slash. It represents the height of the tyre's sidewall as a percentage of its width. So in a 225/45 R17 tyre, the sidewall height is 45% of 225 mm.

(R17) RIM DIAMETER:This is the diameter of the rim in inches. A 225/45 R17 tyre fits on a 17-inch rim.
