FAQs

How do you calculate tire aspect ratio? The tire aspect ratio is calculated by dividing the tire’s sidewall height by its width. It is typically expressed as a percentage. For example, if the sidewall height is 70 millimeters and the tire width is 205 millimeters, the aspect ratio would be 70/205 * 100 = 34.15%.
