What is the aspect ratio of a motorcycle tire?
The aspect ratio of a motorcycle tire is typically expressed as a percentage and represents the ratio of the tire’s sidewall height to its width.

How do you calculate tire aspect ratio? To calculate the aspect ratio of a motorcycle tire, divide the height of the tire’s sidewall (measured from the rim to the tread) by the tire’s width. Then, multiply the result by 100 to get the aspect ratio as a percentage.

What does 72w mean on a motorcycle tire?
