What is the difference between 87h and 91v tires?
1 Answers
The differences between 87h and 91v tires are as follows: 1. Different representations: h and v indicate the maximum speed rating. h represents a maximum speed of 210 km/h, while v represents a maximum speed of 240 km/h, ensuring safety within this range. 87 and 91 refer to the load index of a single tire, but they represent different weight capacities. 2. Different maximum speeds under load: v stands for 240 km/h, while h represents 210 km/h. 3. Different stability levels: Both the load index and the maximum speed rating under load must be consistent, especially for tires on the same axle. Otherwise (during high-speed driving), it may affect the vehicle's handling stability and pose certain safety risks.
