Tires are not made of only rubber; instead, they are precision products composed of multiple composite materials. Rubber serves as the basic raw material for tires, but to meet various performance requirements such as wear resistance, load-bearing capacity, elasticity, and anti-aging properties, it needs to be combined with reinforcing materials, framework materials, additives, and more. The material combinations vary depending on the specific structural part.
Rubber acts as the "matrix" of tires, but it is not a single type; rather, it is a mixture of natural rubber and synthetic rubber. The rubber formulations vary significantly across different parts of the tire, and different types of rubber also have distinct characteristics.
