Load Index

The load rating (represented by the numerical value) is related to the maximum weight that tyre can carry. So in this case 105 would refer to a load capacity of 925kg, with most passenger vehicle load indexes range from 62 to 126.

In all instances the tyres load index must meet or exceed the value displayed on the vehicles placard.

Speed Symbol

The speed category symbol, for example 'S', indicates the maximum speed at which the tyre can carry a load corresponding to its load index. So in this case, 'S' would refer to a maximum speed of 180km/hour.
