Development prospects and significance of tire retreading

Tire retreading is a way to recycle used tires, as well as the extension and processing reuse of the tire industry. It is of great significance for promoting the comprehensive utilization of resources, promoting the transformation of economic growth mode and sustainable development. In terms of its prospects, used tire retreading is an indispensable industry in the transportation of the automobile industry, just like the tire industry.

       Motor vehicle tires, the carcass life is much longer than the tread life (such as aircraft tire carcass life is about 6 times the tread life, trucks about 3 times, cars about 1 times), so motor vehicles must be used many times Refurbishment only completes its resource life. The ratio of new tires to retreaded tires in the world is about 10: 1, and it can reach more than 5: 1 in advanced industrialized countries. In 1998, China's new tire production was 85.85 million, while the retreaded tires are estimated to be about 3 million. The ratio of new tires to retreaded tires is about 28: 1, which is much lower than the world level and even lower than that of developed countries. There were 28.104 million retreaded tires with an output value of US $ 2.266 billion.

China's tire-turning enterprises are more typical "small and complete" workshop-style enterprises. The scale of the enterprise is small, and there are too many tire turning factories in some places, such as Beijing.
