What does 98W on a tire represent?
1 Answers
98 is the load index of the tire, indicating a maximum load capacity of 750KG per tire. W represents the speed rating, which denotes the maximum speed the tire can sustain under specified conditions with a given load. The W speed rating corresponds to a maximum speed of 270 kilometers per hour. Tires are one of the most critical components of a vehicle, serving several key functions: 1. Supporting the entire weight of the vehicle, bearing the load, and transmitting forces and moments in other directions; 2. Transmitting traction and braking torque to ensure good adhesion between the wheel and the road surface, thereby improving the vehicle's power, braking, and off-road performance; working in conjunction with the suspension system to absorb shocks during driving and dampen resulting vibrations; 3. Protecting vehicle components from severe vibrations and premature wear, adapting to high-speed performance while reducing driving noise, and ensuring safety, handling stability, comfort, and fuel efficiency.
