How do I find my tire size?

The size of a tire is printed onto the side of the tire – on the area known as the sidewall. When looking for the size, you will see that it is made up of a series of numbers and letters. In the above example, each section breaks down as follows:

 

205 - Width of the tire in millimetres
55 - Height of the tire sidewall as a percentage of the width. In this case 55%. Also known as the aspect ratio.
R16 - The diameter of the tire's inner rim in inches
91 - Load Rating of the Tire.
V - Speed Rating. Indicates the maximum speed for the tire when at full load.
