Tires have a variety of excellent properties, such as wear resistance, corrosion resistance, etc., but these advantages also become disadvantages when the service life of the tire is exhausted. After the waste tires are produced, because the used tires also have the above characteristics, their reuse has become a problem that they have to pay attention to. China is a tire-producing country and a tire-producing country. The annual output of used tires has been rising. According to the Tire World Network, in 2008, the production of used tires in China was around 7.4 million tons, and it continued to climb in the following years. By 2013, the production of used tires had exceeded 10 million tons. According to the source, the current domestic used tires are mainly divided into two categories: passenger car tires and commercial vehicle tires, of which commercial vehicles are mainly truck tires. Relatively speaking, the change in the overall production volume of passenger car tires mainly changes with the changing trend of passenger car ownership, and the market operation is relatively normal. However, there are many problems with large trucks. For a long time, the domestic logistics industry has been affected by many factors, and the problem of overloading is more prominent. It is often seen on highways that more than 20 tires and ultra-long trucks with a capacity of over 100 tons are equipped.

Excessive overloading has greatly shortened the service life of tires, which is also an important reason for the large increase in the production of used tires each year. According to the calculation of Tire World Net, the number of used tires produced by large trucks in China each year is close to 200 million, especially in the increase in infrastructure construction in the past two years. With the development of the domestic logistics industry, this situation is becoming more and more intense. After the waste tires are produced, because their main components are rubber and carbon black, their corrosion resistance is very strong. How to effectively treat and make wastes is a common concern. Waste tires were refurbished to account for 5%, thermal cracking accounted for 10%, and the relative proportion was not high. A small number of used tires were used for other purposes, such as fixing soil on the slopes, pier fenders, and so on.

However, most of the used tires are still effectively reused. 46% of used tires are used to produce reclaimed rubber and rubber powder, and reclaimed rubber and rubber powder can be used again to produce rubber products. A small amount of rubber powder is directly applied to asphalt modification, and most of it is used to produce reclaimed rubber. Glue, reducing resource consumption, and improving production costs have all played a positive role. At present, this has become the main method of waste tire recycling.
