What is the difference between 91v and 91h?
1 Answers
91v and 91h mainly differ in their speed ratings. 91 is the load index, indicating the load standard that the tire can bear under different air pressures. A tire with a load index of 91 can support 615KG at 2.5Bar. v and h are speed symbols, representing the maximum speed the tire can travel at, with v=240km/h and h=210km/h. Here is more information about speed ratings: 1. The speed rating indicates the maximum speed at which the tire can carry a specified load under defined conditions. 2. Different tires will have letters on their sidewalls representing the speed rating, which denotes the certified speed rating of the tire from 4.8 km/h to 300 km/h.
