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 a tire can bear when driving at the speed specified by the speed symbol under standard usage conditions. This code divides loads from 45kgf to 136CH30 into 280 grades (U279), with each grade having a load difference of 3%. This code is listed in international standards and is required to be marked on the tire. Tires are circular elastic rubber products assembled on various vehicles or machinery for ground rolling, usually mounted on metal rims. They support the vehicle body, cushion external impacts, maintain contact with the road surface, and ensure the vehicle's driving performance.
