What does 3T on tires mean?

[DelMariana]

3T on tires refers to: TREADWEAR wear resistance index, TRACTION traction ability, and TEMPERATURE temperature index. The specific meanings of 3T are: 1. The wear resistance index reflects the tire's wear resistance. 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. 2. The traction index is a parameter that measures the tire's grip performance on wet and slippery roads. 3. The temperature index grade reflects the tire's own heat dissipation capability. As the speed increases, the temperature of the tire also rises. If the tire's own heat dissipation capability is poor or cannot withstand the rapidly rising temperature, its stability during high-speed driving will be greatly compromised. The higher the grade of the tire, the more it can reduce heat generation, and the longer its service life.
