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.

Having driven for decades, markings like 98w on tires are extremely common to me—it's a combination of load index and speed rating. The 98 indicates the maximum weight the tire can bear, approximately 750 kg, which is a critical point because overloading your vehicle can easily lead to tire blowouts. As for the 'w,' it's the speed rating, meaning the tire can handle speeds up to 270 km/h, especially crucial for highway driving. I remember once on the highway, choosing the wrong speed-rated tires caused them to overheat at high speeds, leading to unstable tire pressure. From a safety perspective, always check your vehicle manual for this 98w specification when buying or replacing tires—don’t overlook the details to avoid accidents. Regular maintenance should also include verifying tire parameters to ensure they match your vehicle model, which helps extend tire life and reduce fuel consumption.

This 98W, I learned from the mechanic. 98 is the load index of 750kg, and W represents a maximum speed of 270km/h. Simply put, it tells you how much weight the tire can handle and how fast it can go, directly affecting safety and performance. Since I often drive an SUV with luggage, I pay special attention not to exceed the load index; tires with a higher W rating are suitable for high-speed driving, but may not be necessary for city use. When changing tires, match the original factory specifications—don’t opt for cheaper, lower-grade tires, or you might end up like me last time, experiencing vibrations at high speeds after installing lower-grade tires. Make it a habit to regularly check tire markings to reduce the risk of malfunctions, and share these practical tips with friends.

The number 98 in 98W represents the load index, indicating a maximum load capacity of approximately 750 kilograms. The W denotes the speed rating, with a maximum speed of 270 kilometers per hour. These specifications are crucial for driving safety, as overloading or exceeding the speed limit may lead to tire blowouts and loss of control. During long-distance drives, I frequently check these markings to ensure the tires are suitable. I recommend everyone verify the specifications when purchasing tires or during maintenance to avoid risks and enhance stability. Details determine success or failure—never overlook them.

When you see a tire marked 98W, the 98 represents a load capacity of 750kg, and W indicates a speed rating of 270km/h. These parameters must match your vehicle's requirements when replacing tires. From my experience, always check the original tire specifications before purchasing to avoid dangers caused by insufficient load capacity or exceeding speed limits. For example, driving fast on low-speed-rated tires can lead to overheating and blowouts. I recommend regular maintenance to check tire pressure and wear, and promptly replace with reliable tires to ensure safe driving. Simple habits can provide significant safety protection.
