What is the difference between 91V and 91H tires?
2 Answers
The differences between 91V and 91H tires: 1. The maximum speed under load varies: V represents 240 km/h; while H stands for 210 km/h. 2. There is also a difference in price: Tires of the same size and specification, 91V tires are more expensive than 91H, as their load capacity is stronger than that of 91H. Additional notes: 1. 91V and 91H tires cannot be mixed. 2. When purchasing tires, the original vehicle should be equipped with tires of the same specification, structure, manufacturer, and tread pattern. 3. In other words, whether it's the load index or the maximum speed under load, they need to be consistent, especially for tires on the same axle. Otherwise, it may affect the vehicle's handling stability during high-speed driving, posing certain safety risks.
The difference between tire markings 91V and 91H mainly lies in the speed rating. The number 91 indicates the same load capacity for both, able to withstand 615 kg, but V represents a speed rating of 240 km/h, while H is 210 km/h. I usually prefer steady driving, so I pay more attention to this speed difference. The 91V is suitable for high-speed racing or aggressive driving, as it offers better stability and stronger grip at high temperatures. The 91H is ideal for daily city driving, with a maximum speed of 210 km/h being generally sufficient, especially on flat roads where the difference is minimal. If the vehicle has a high-horsepower engine, the 91V is recommended to avoid the risk of overspeeding. On the other hand, for ordinary family cars, the 91H is more economical and wears slower. Weather conditions should also be considered—the 91V provides slightly better control during high-speed driving in the rain. However, I suggest choosing based on actual driving habits rather than blindly opting for a higher rating and wasting money.
