Load index ratings
The majority of tyres carry coded markings on them, which correspond to their load carrying and maximum speed capabilities.
The load index is a numerical code associated with the maximum load a tyre can carry (see load index table) at the speed indicated by its speed symbol (see Speed Symbol table) under service conditions specified by the tyre manufacturer.
For example,
91 = Load Index (91 equates to a weight of approximately 615 kg)
