Tread: The part in contact with the road surface makes the car have the performance of driving and braking through friction, and should have good wear resistance, puncture resistance, impact resistance, heat dissipation and other properties.
Carcass: The ply layer in the tire, the main stressed part of the tire, which is impact-resistant and should have good flexural resistance during driving.
Belt layer: steel wire cord between the tread and the carcass protects the carcass, inhibits the deformation of the tread, maintains the grounding of the tread, and improves wear resistance and driving stability.
Canopy layer: a special ply layer above the belt layer, which inhibits the movement of the belt layer during tire driving, prevents the belt layer from detaching during high-speed driving, and maintains the stability of the tire size at high speed.
Bead: The rubber wire is wound in a certain shape (four-corner or hexagonal shape), which plays the role of installing the tire on the rim to fix the tire.
Triangular rubber strip: the filler material on the steel wire ring in the tire to prevent the bead from being dispersed, slow down the bead impact, protect the bead, and prevent air from entering during forming.
Inner liners: The parts of tubeless tires that maintain airtightness, made of special rubber, which acts as an inner tube.
