What are the components of a tire?

[CatherineDella]

Automobile tire materials are primarily composed of natural rubber or synthetic rubber. Natural rubber has superior comprehensive performance compared to synthetic rubber, which is why premium tires often use natural rubber. To endow the rubber with the properties required for tire manufacturing, various chemical materials, known as chemical additives, must be blended into the rubber. Additional information: 1. Composition: Tires are typically made up of three parts: the outer tire, the inner tube, and the flap. Some tires do not require an inner tube, as they feature an inner layer of rubber with excellent air retention properties and must be used with specialized rims. Tire structures worldwide are evolving towards tubeless designs, radial structures, flat profiles (with a low ratio of tire section height to width), and lightweight construction. 2. Outer tire: The outer tire consists of the carcass, the breaker (or belt layer), the tread, the sidewall, and the bead. The cross-section of the outer tire can be divided into several distinct zones: the crown area, the shoulder area (tread slope), the flex area (sidewall area), the reinforcement area, and the bead area.
