How is the aspect ratio calculated?

Aspect ratio is the percentage of a tire's section height to its section width, simply put, it's the height-to-width ratio of the tire. Here are specific details about aspect ratio: 1. Tire section: The tire section consists of the shoulder, sidewall, and bead. The sum of their heights is the tire section height. After installation, since the bead is hidden inside the rim, the measured height from the rim to the outer section (tread) is slightly less than the tire section height. 2. Example: For a tire with the specification 205/60R15, its maximum section width is 205 millimeters, the aspect ratio is 60%, the inner diameter is 15 inches, and the aspect ratio of 60% means the tire section height is 205*60%=123mm.
