Rim Diameter
Rim diameter is the measurement across the inside of the wheel rim where the tyre bead seats, expressed in inches. In a 205/55R16 tyre, the rim diameter is 16 inches. Tyres must be fitted to rims of the matching diameter — an incorrect match makes safe fitting impossible. Modern vehicles commonly use rim diameters from 14 to 22 inches.
