What do 91V and 94V mean on tires?

[LaZane]

91 refers to the tire load index of 615kg, and V stands for the speed rating with a maximum speed of 240km/h. 94=This tire has a maximum load capacity of 670kg, V=The maximum speed of this tire is 240 kilometers per hour. Tires are one of the most important components of a vehicle, and their main functions include: 1. Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and moments in other directions; 2. Transmitting traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the vehicle's power performance, braking performance, and passability; working together with the vehicle suspension to mitigate impacts during driving and dampen the resulting vibrations; 3. Preventing severe vibrations and early damage to vehicle components, adapting to the high-speed performance of the vehicle and reducing driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.
