Can I replace 91V tires with 91H tires?

[JayceDella]

91V and 91H tires cannot be mixed. When purchasing tires, the original tires installed on the vehicle should be of the same specification, structure, manufacturer, and tread pattern. Both the load index and the maximum speed under load must remain consistent, especially for tires on the same axle. Otherwise, it may affect the vehicle's handling stability at high speeds, posing potential safety hazards. Below is some relevant information about tires: Tire lifespan: The wear lifespan of tires is approximately 30,000 to 50,000 kilometers. If the tires have not reached the wear limit or mileage but have been in use for 5 years or show significant sidewall cracking, they should be replaced. Tire material: The main component of tires is rubber. The maximum storage and anti-aging duration for rubber, from natural latex to ethylene-propylene and nitrile, does not exceed 10 years. The average service life for various rubber products in use is 3 to 5 years.
