Tire Finder Width Graphic

Width (130/90 16)

The first number in a tire size represents the nominal width (usually in millimeters). Width is measured in a straight line from the furthest point on one sidewall, across the tread, to the furthest point on the opposite sidewall.


Tire Finder Aspect Ratio Graphic

Aspect Ratio (130/90 16)

The aspect ratio indicates the height of the tire's cross-sectional profile. It is expressed as a percentage of the tire's width, so an aspect ratio of 55 means the tire's cross-section is 55% as high as it is wide.

Rim Size (130/90 16)
