What are the three T indices of tires?

The three T indices of tires are Treadwear Index, Traction Index, and Temperature Index. Below are the detailed explanations of the three T indices of tires: Treadwear Index: The Treadwear Index reflects the wear resistance of the tire. The higher the value, the more wear-resistant the tire is, and the harder the rubber, resulting in poorer comfort. Conversely, the lower the value, the less wear-resistant the tire is, and the softer the rubber, leading to better comfort. Generally, a Treadwear Index between 280-320 is considered moderate. Traction Index: TRACTION A indicates the Traction Index, with grade A proving stronger traction. Traction levels from highest to lowest are AA, A, B, and C, with grade C being the lowest. Temperature Index: TEMPERATURE A represents the temperature grade of the tire, with grade A indicating a higher resistance to high temperatures. For passenger car tires, the temperature grades from highest to lowest are A, B, and C.
As a seasoned driver with over a decade of experience, I find the 3T index of tires quite crucial—it helps us choose the right tires for a safer and more worry-free drive. The first T, the treadwear index, indicates the tire's durability; the higher the number, the longer the tire lasts—for instance, a rating above 300 means it can last several years. The second is the traction index, which reflects the tire's grip on wet surfaces, graded as A or AA, with AA being the highest level, ensuring no slipping during rainy drives for maximum safety. Lastly, the temperature index is graded as A or B, with A being the best, as it dissipates heat quickly at high speeds, reducing the risk of blowouts. When selecting new tires, I always check these ratings: high treadwear saves money, good traction prevents accidents, and strong heat dissipation ensures reliability, making daily driving both convenient and safe. I also recommend regularly checking tire condition and maintaining balanced tire pressure to extend their lifespan.
