The smallest rim diameter (22mm) is intended for women who have never been pregnant.

The lake is centered within an impact crater with a rim diameter of 18 km that formed 3.6 million years ago (Pliocene).

It was 24.81mm in length, 5.36mm in case diameter and 6.94mm in rim diameter at base.

The new rim diameter is close to the case wall diameter.

The second number (nominal rim diameter) is the inner diameter of the tire when it is mounted on the rim.

The overall diameter of the tire is then the rim diameter plus twice the tire's section height.

It has the same rim diameter as the 20x102mm but a different length and contour.

Vehicle tyres mark the rim diameter in inches and the width in millimetres.

A car tyre marked '165/70R13' has a width of 165 mm, an aspect ratio (profile) of 70% and a 13-inch rim diameter.

One way to estimate wheel diameter is to add twice the nominal tyre cross-section to the rim diameter.
