What does 97w mean on a tire?
2 Answers
Tire 97w indicates the load index and speed rating of the tire. Here, 97 means that a single tire can bear a maximum weight of 730KG, and w means that the tire can withstand a maximum vehicle speed of 270km/h. Additional information: Speed rating: The speed rating refers to the maximum speed that a tire can achieve under specified load and inflation pressure standards. Common speed ratings for most vehicles on the market are H and V, while some high-performance vehicles use W and Y (don’t assume that H and V are similar—their tire structures differ, leading to price variations).
After driving for so many years, I often see markings like 97W on tires. Actually, the number 97 indicates how much weight the tire can bear, like a load capacity index—97 can roughly support 730 kilograms. The W represents the maximum safe speed of the tire at high speeds, which is around 270 km/h. I remember once on a long-distance trip, I noticed how these codes affect handling and wear, especially on uneven roads. After understanding this, I became more careful about regularly checking tire pressure and wear to avoid overloading or speeding. Choosing the right tires can enhance driving safety—for example, W-rated tires are suitable for drivers who frequently drive at high speeds. Overall, 97W is an important marking that gives drivers more peace of mind and makes maintenance easier.
