What is the Tire Traction Index?

[MacTanner]

Tire traction index refers to the ability to support vehicle handling. The following is an introduction on how to choose tires: 1. Look at the tire's ply rating: The number is usually represented as 12P.R, indicating 12 plies. This number signifies the nominal number of tire cord layers, not the actual number. A higher number indicates greater tire strength, meaning the tire is thicker and more durable. 2. Look at the tire's cord material: The material of the tire greatly affects its quality. Common materials include N (nylon), G (steel wire), M (cotton), and R (rayon). In China, these are represented by their initials, which is quite characteristic and easy to recognize. These letters usually follow the ply rating. 3. Look at the tire's 3T indicators: These are the treadwear index, traction index, and temperature index. Within the same brand, a higher treadwear index indicates better wear resistance, with 300-540 typically being all-season tires. The traction index is divided into AA, A, B, and C, with AA being the best. Usually, A is common, but B should be avoided as it relates to driving safety—always choose a higher grade. The temperature index is divided into A, B, and C, with A being the best at preventing the tire from generating heat and thus avoiding blowouts.
