What does 98W on a tire mean?
3 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.
The number 98 in the tire specification 98W represents the load index, indicating a maximum load capacity of approximately 750 kilograms, which is crucial for daily vehicle use. The letter W denotes the speed rating, with an upper limit of 270 kilometers per hour, ensuring the tire won't deform due to heat buildup during high-speed driving. From a safety perspective, mismatching the tire's load capacity or speed rating with the vehicle's weight or driving speed can lead to tire failure and loss of control. For instance, I once experienced a tire blowout due to excessive speed causing overheating, so it's essential to choose tires according to the manufacturer's specifications. Winter snow tires also affect these parameters, so regular tire inspections are advised—don't cut corners on safety, as life comes first.
