1.Sidewall

The sidewall of a scooter tire provides structural support and protection. It is made of a combination of rubber and reinforcing materials such as cords. The sidewall contains important information such as the tire size, load - carrying capacity, and speed rating.

The sidewall's strength is important as it helps to maintain the shape of the tire and withstand lateral forces during cornering. A well - constructed sidewall can also absorb shocks and vibrations from the road, improving ride comfort. Some scooter tires have reinforced sidewalls for added durability, especially for scooters that are used in more demanding conditions such as carrying heavy loads or riding on rough roads.

2.Inner Structure

Inside the tire, there is a carcass. The carcass is usually made of layers of cords, which can be made of materials like polyester, nylon, or steel. The cords are arranged in a specific pattern to provide strength and flexibility to the tire. For example, in a radial - ply tire (a common construction for scooter tires), the cords run radially from the bead (the part of the tire that sits on the rim) to the tread.

The bead is a crucial part of the tire that seals the tire to the rim. It is usually made of a high - strength steel wire coated with rubber. The bead ensures that the tire is properly seated on the rim and maintains air pressure. A properly functioning bead is essential for safety as it prevents the tire from coming off the rim during riding.
