As the aspect ratio decreases, the tyre section height (sidewall hight) becomes smaller. 3 - (R) Radial Tyre 4 - (13) Rim Diameter (inç) 5 - (82) Load Index: It refers to the maximum load that the tyre can carry at the rated speed. The load index is a numerical code associated with the maximum load a tyre can carry at the speed indicated by its speed symbol.
