[0002] There are several shortcomings in the existing automobile tires in terms of puncture-proof and air leakage, mainly including vulnerability, maintenance cost and weight increase. Although modern tires use a variety of technologies to improve their puncture resistance, such as using thicker tread and sidewall materials, they are still easily punctured by sharp objects such as nails, glass fragments, etc., resulting in air leakage. The reason for these shortcomings lies in the physical properties of the tire material, as well as the various road conditions and foreign objects that the tire inevitably encounters during use. In order to improve the puncture-proof performance, some tires use built-in leak-proof layers or self-sealing glue, which reduces the risk of air leakage to some extent, but also increases the weight and production cost of the tire. These additional layers may affect the heat dissipation performance and rolling resistance of the tire, thereby affecting fuel efficiency and tire life, so there is an urgent need for a puncture-proof tire to solve the above problems.
