The width of a tire is referred to as its section width. This is the width of an inflated tire in millimeters at its widest point from sidewall to sidewall.

The section height of the tire is measured in millimeters also. The section height is approximately the distance from the rim to the tread surface of the tire when it is not carrying any weight.
