What is Treadwear?

Treadwear is not a specific brand of tires. It is a parameter that indicates the耐磨性能 of tires. Since tires are made of rubber, they are prone to aging and loss of performance over time. Therefore, they need to be replaced regularly. Treadwear is one of the three important indicators of tire quality and suitability, along with traction and temperature index, which are collectively known as the 3T index.

Typically, tires are made up of three parts: the outer layer, inner layer, and the cushion. The inner layer has a good gas-proof rubber layer, and the outer layer is composed of the tire body, tire side, and tire ring. The tire body and tire ring form the load-bearing structure of the inflated tire.

Tires are essential components of a car, as they are in direct contact with the road surface and work together with the suspension system to absorb shocks during driving, ensuring a comfortable ride and good road adhesion, which in turn improves the car's traction, braking, and through-line.

It is important to note that the 3T index is not only affected by treadwear but also by other factors such as the type of rubber used, the structure of the tire, and the driving conditions. Therefore, it is important to choose a high-quality tire that suits your driving style and needs.
