Briefly introduce what tires are and what are their functions?

Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. They are usually installed on metal rims, can support the vehicle body, buffer external impact, achieve contact with the road surface and ensure the driving performance of the vehicle.

Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation.

The role of tires

First, tires are the carriers of force transmission between vehicles and roads. Driving force, braking force, steering force, etc. are transmitted through tires, thereby realizing the driving, braking, steering and other operations of the car.

Second, support vehicle load. The load of the vehicle causes the tire to sink until the average pressure of the tire contact area is balanced with the inflation pressure inside the tire.

Third, reduce and absorb the vibration and impact force during the driving process of the car, and avoid early damage to automobile parts due to severe vibration. At the same time, it adapts to the vehicle's high-speed driving state and reduces driving noise, ensuring driving safety, comfort, handling stability and fuel economy.
