What does Load Index mean?
For the average individual, the meaning of speed symbols and load indexes on automotive tyres are not common knowledge. This makes sense, as most passenger cars with the correctly chosen tyres won’t ever come close to the maximum speed or weight capacity indicated on the tyres.
The load capacity index of a tyre, also known as the load index, is a numerical code that indicates the maximum weight capacity that a tyre can safely carry. It is represented by a number found on the sidewall of the tyre, following the tyre size.
The load capacity index is standardised and correlates to specific weight values. Each index number corresponds to a specific load capacity in kilograms or pounds.
For example, a load index of 91 may indicate a load capacity of 615 kg, while a load index of 110 may indicate a load capacity of 1060 kg.
There is no standard pressure for car tyres but normally it is between 1.8 and 2.2 bar or 30 to 35 PSI.
