What is the tire load index?
1 Answers
Tire load index, also known as tire load rating, refers to the numerical code indicating the maximum load capacity that a tire can bear when operating at the speed specified by its speed symbol under standard usage conditions. The load index of tires ranges from 70 to 109, corresponding to maximum load capacities of 335-1030kg. Exceeding the tire's maximum load capacity won't cause immediate damage, but prolonged overloading will lead to tire fatigue, shorten the tire's service life, and may even result in a blowout in severe cases. Additional information: The load index and maximum load capacity of each tire are molded on the tire sidewall. For example, in the tire specification 195/65-R15-91V, the load index is 91, which corresponds to a maximum load capacity (single tire) of 615 kilograms.
