Automobile tire is one of the important parts of automobile. It is in direct contact with the road surface and works together with automobile suspension to reduce the impact of automobile driving, thus ensuring good riding comfort and riding comfort of automobile. Ensure good adhesion between the wheel and the road surface; Improve the traction, braking and passability of the car; Bearing the weight of the car, people pay more and more attention to the important role of tires in the car. 1892, Burrimier of Britain invented the curtain cloth, and 19 10 was used for production. This achievement not only improves tire quality and expands tire varieties, but also makes tire molding possible. With the improvement of tire quality requirements, the quality of cord fabric has also been improved. Cotton cord fabric was replaced by rayon, which was replaced by nylon and polyester cord with better strength and heat resistance in the late 1950s. With the development of radial tire, steel cord has strong competitiveness. Matt created the carbon black reinforced rubber in 1904, and used it to reinforce the tread compound on a large scale after the tire used the cord fabric, because before that, the canvas was damaged faster than the tread in tire use, and the amount of carbon black in the compound increased rapidly. In 1930s, only about 20 parts of carbon black were used in every 100 block of raw rubber.

At this time, the tread is mainly made of carbon black, and the carcass is not used, which has reached more than 50 copies. Before carbon black was added to the tread, the tire was polished after driving about 6000km, and the mileage of the tire was greatly improved after carbon black was added. A set of truck tires can travel about 654.38+ million kilometers, and even 200,000 kilometers on good roads. With the development of automobile industry, tire technology is constantly improving and perfecting, such as the transition from low-pressure tires to ultra-low-pressure tires from the early 1920s to the mid-1930s; In the 1940 s, tires gradually transitioned to wide rims; The appearance of tubeless tires in the late 1940s; In the late 1950s, low-profile tires came out and so on.
