The ABCs of Tyre Dimensions

The first number stands for the width of the tyre at its widest point.

The second number shows the aspect ratio of the sidewall height to the width.

The R stands for "Radial" or steel belt. The third number indicates the tyre diameter or rim diameter in inches.

The fourth number is the load capacity index. The heavier the vehicle, the higher this index.

The letters (in the example image "V") provide information about the permitted speed – they are defined per vehicle (model/version). The scale for the vast majority of passenger cars starts with Q and goes up to Y. The most important ones are S (up to 180), T (up to 190), H (up to 210), V (up to 240), and VR (over 240).
