What does 98W on a tire mean?
2 Answers
Tire 98W refers to: 98 is the load index of the tire, corresponding to a maximum load capacity of 750 kilograms per tire. W represents the speed rating of the tire, indicating the maximum speed at which the tire can carry a specified load under specified conditions, with W's maximum speed being 270 kilometers per hour. Tires are crucial 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 to ensure good adhesion between the wheel and the road surface, thereby improving the vehicle's power, braking, and off-road capabilities, while working with the vehicle's suspension to cushion impacts during driving and dampen resulting vibrations; 3. Preventing severe vibrations and premature damage to vehicle components, adapting to the vehicle's high-speed performance, reducing driving noise, and ensuring driving safety, handling stability, comfort, and fuel efficiency.
What does 98W on a tire mean? Simply put, 98 is the load index, indicating that the tire can support a maximum load of around 750 kilograms. For example, if your car is fully loaded with passengers or heavy cargo, the tire can handle it. The W stands for the speed rating, meaning the tire can safely operate at speeds up to 270 kilometers per hour, making it suitable for high-speed driving. You need to check these ratings when choosing tires; otherwise, if the load is too heavy or you drive too fast, the tire might fail and cause a blowout. I remember once driving on a trip with the car packed full of luggage and cruising at high speed—luckily, the tires matched these numbers, ensuring a smooth ride. Regular maintenance, like checking tire pressure and wear, is also crucial to maintain safety. Exceeding these limits is no joke.
