Tire refurbishment is a positive way to recycle and reuse waste tires, an extension and processing of the tire industry, and has positive significance in promoting resource conservation and comprehensive utilization, transforming economic growth patterns, and promoting sustainable development. In terms of its prospects, the refurbishment of waste tires, like the tire industry, is an indispensable industry in the automotive industry and transportation.
Due to safety and other reasons, the tire life of motor vehicles is much longer than the tread life (for example, the tire life of aircraft tires is about 6 times the tread life, that of heavy-duty vehicles is about 3 times, and that of sedans is about 1 time). Therefore, motor vehicle use requires multiple refurbishments to complete its resource life. The international production ratio of new and refurbished tires is about 10:1, with industrialized countries reaching over 5:1. In 1998, the production of new tires in China was 85.85 million, while the estimated number of retreaded tires was about 3 million. The ratio of new tires to retreaded tires was about 28:1, far lower than the world level and even lower than the level of developed countries. For example, in 1998, the United States retreaded 28.104 million tires, with a production value of 2.266 billion US dollars.
Our country's tire flipping enterprises are a typical "small and comprehensive" workshop style enterprise. The scale of the enterprise is small, and there are too many tire flipping factories in some places, such as Beijing.
