W810

The width of the tyre indicated in millimeters, measured from sidewall to sidewall.

Aspect ratio describes the height of the sidewall as a percentage of the width of the tyre. Touring tyres usually have a higher aspect ratio, indicating a higher sidewall and resulting in a smoother ride. High performance tyres usually have a lower aspect ratio, resulting in better lateral stability.

This number specifies the outer edge of a wheel, holding the tyre, measured in inches.

A numerical code associated with the maximum load a tyre can carry at the speed indicated by its Speed index. A higher number indicates that the tire has a higher load capacity.

The letter indicating the maximum speed at which the tyre can carry a load corresponding to its Load Index.
