How to Measure Tire Size: Step-by-Step Guide

Step Description
1 Locate the tire size information on the sidewall of your current tires.
2 Identify the three essential measurements: tire width, aspect ratio, and wheel diameter.
3 Measure the tire width by using a measuring tape across the widest point of the tire.
4 Determine the aspect ratio by dividing the tire’s height by its width.
5 Measure the wheel diameter by using a ruler or tape measure across the center of the wheel.
6 Write down the measurements in the format: tire width/aspect ratio R wheel diameter.
7 Consult your vehicle’s owner’s manual or a trusted tire professional for recommended tire sizes.
