What is the difference between 91v and 94v on tires?

[OKaylee]

The difference between 91v and 94v on tires: 91v indicates a load index of 615kg; 94v indicates a load index of 670kg. The functions of tires are as follows: 1. Prevent severe vibrations and premature damage to vehicle components, adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency. 2. Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 3. Transmit traction and braking torque, ensure good adhesion between the wheels and the road surface to improve the vehicle's power, braking, and passability; work together with the vehicle suspension to mitigate impacts during driving and dampen resulting vibrations.
