What is the material of tires?
1 Answers
Tires are mainly composed of natural rubber or synthetic rubber. Tires are circular elastic rubber products assembled on various vehicles or machinery to roll on the ground. Tires are often used under complex and harsh conditions, enduring various deformations, loads, pressures, and high and low temperatures during operation. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. Characteristics of rubber tires: Rubber has good elasticity, and using rubber for tires can reduce the sense of bumps during driving. However, natural rubber has inherent disadvantages in wear resistance, heat melting, and grip, making it unable to withstand friction and easily worn out. Carbon black tires: Black tires with added carbon black can achieve excellent wear resistance and anti-aging properties, extending the tire's lifespan by 10 times (tires without carbon black have a lifespan of less than 8,000 kilometers). In addition to being more wear-resistant, black tires can also resist ultraviolet rays, preventing tire cracking caused by UV exposure. Precautions: Tires are rubber products, and the shelf life of rubber is generally 3 years. Therefore, when choosing tires, it is essential to pay attention to the production date of the tire. For tires produced after 2000, the last four digits of the manufacturing number indicate the year and week of production. For example, "1907" means the tire was produced in the 19th week of 2007.
