What Do the Tire Specifications Represent?

[Ralph]

Automobile tire specifications can be identified through the markings on the side. Below is a detailed introduction to the tire parameters: 1. The 3T index of a tire refers to the treadwear index, traction index, and temperature index. 2. Treadwear index TREADWEAR-220 indicates that the tire's treadwear index is 220. Generally, a treadwear index between 280-320 is considered moderate; the higher the number, the more wear-resistant the tire. More wear-resistant tires are harder, noisier, and less comfortable. 3. Traction index TRACTION-A indicates that the traction index is grade A, which proves strong grip. 4. Temperature index TEMPERATURE-A indicates that the tire's temperature grade is A, the highest level, meaning the tire has the best structural stability at high speeds. 5. The structural parameters of the tire mainly refer to the number of steel belt layers, cord layers, and nylon layers in the tread and sidewall. The more layers, the higher the tire's strength, and the lower the probability of tire blowouts or punctures.
