Bicycle tires typically consist of three parts: tread, sidewall, and bead. Among them, the tread is the part where the tire directly contacts the ground, and its material is mostly rubber or synthetic rubber, which has excellent wear resistance and skid resistance. The tire wall is responsible for supporting the tire structure, generally using high elasticity, fatigue resistant nylon or polyester fiber materials. The tire bead is the part that connects the tire to the wheel hub, usually made of steel wire or alloy materials to ensure a tight connection between the tire and the wheel hub.

The size and pattern design of bicycle tires are also important factors affecting the riding experience. Different sizes and patterns are suitable for different cycling scenarios and road conditions. For example, the tires of mountain bikes usually have deeper patterns and wider tread to increase grip and stability; The tires of road bicycles are smoother and narrower to reduce resistance and increase speed.

Structurally, bicycle tires are mainly divided into two types: inner and outer tires and vacuum tires. The structure of the inner and outer tires is relatively traditional, with the inner tire responsible for inflation and the outer tire providing contact with the ground. This structure is relatively simple and easy to maintain, but the inner tube is prone to damage. Vacuum tires, on the other hand, do not require inner tubes. The entire tire is composed of a sealed airtight layer, which not only reduces the possibility of damage but also improves the durability of the tire.

Bicycle tires, as an important component of bicycles, not only carry the weight of the rider, but also directly determine the comfort and safety of riding. With the advancement of technology and the improvement of manufacturing processes, modern bicycle tires have significantly improved in materials, structure, and performance, providing riders with a better riding experience.
