What is tire height?

It’s the height of the sidewall measured from wheel rim to top of the tread and expressed as a percentage of tire width. In other words, it’s sidewall height divided by tire width. So to illustrate, if the aspect ratio is 65 then it means the sidewall is 65 percent as high as the tire is wide.

What is the average tire size?

The bigger the aspect ratio, the bigger the sidewall will be. The aspect ratio or profile refers to the height of the sidewall as a percentage of the section width. For example,” 55” means the height is equal to 55{2e1e219470849bf7ec91275b0a9fbc84b08096e911ffdb617f5afdb5ab7ea907} of the 195mm width.

The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65{2e1e219470849bf7ec91275b0a9fbc84b08096e911ffdb617f5afdb5ab7ea907} of the tire’s width.

What is the sidewall height of a tire?

Normal tire size’s sidewall height (from rim to tread) is 50{2e1e219470849bf7ec91275b0a9fbc84b08096e911ffdb617f5afdb5ab7ea907} of its section width. The measurement is the tire’s section height which is also referred to as the tire’s series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall.
