What do the letters on tires represent in terms of speed?
1 Answers
Tire markings T, U, H, V, and Y represent speeds of 190 km/h, 200 km/h, 210 km/h, 240 km/h, and 270 km/h respectively; ZR indicates speeds exceeding 240 km/h. Below are detailed introductions about tires: 1. Tires are primarily composed of high-molecular composite materials, and elevated temperatures accelerate rubber aging; 2. High-speed driving increases the overall temperature of the tire, leading to accelerated tread wear; 3. High-speed driving increases the overall temperature of the tire, leading to accelerated tread wear; 4. Tires have a designed critical speed. When driving at high speeds reaches this threshold, the tire will exhibit a 'standing wave' phenomenon. Continued use under these conditions poses a risk of tire blowout.
