To address the issue of automobile safety, the important component, the automobile tire, has to be said. As is well known, the tire industry has developed today for centuries. Over the course of hundreds of years, the traditional tire production process is improved day by day, and the automation degree of each stage is very high from rubber mixing, component preparation (calendering and extruding), molding and vulcanization to finished product quality inspection. After anything has developed to a certain historical height, it will be very difficult to continue to step to a higher target.

The tires which are commonly used are basically inflated, and if some sharp objects are pressed down during running, the tire burst situation can easily occur, and once the situation occurs, the situation is very dangerous. Therefore, many drivers are always careful to drive on the road, so that the danger is feared, but the tire burst on the road is always happened. Moreover, the production process of the pneumatic tire is complex, the natural rubber consumed in the market is large in scale, and in addition, environmental protection, energy conservation and consumption reduction are more and more emphasized in the global scope, and the current pneumatic tire is not beneficial to environmental protection and resource recycling.

Therefore, a non-pneumatic tire is a type of safety tire, which is a type of tire that uses an elastic filler or support instead of a tire pressure without being inflated. The non-pneumatic tire has the advantages of being free of maintenance, leakage and tire burst and the like, and the problem of the traditional pneumatic tire is solved fundamentally.

Non-pneumatic tires developed on the market today perform well in terms of safety, but generally have the disadvantage of not providing a good enough experience in terms of driving and riding comfort, most notably not being particularly ideal in terms of shock absorption and shock absorption, resulting in increased driving resistance and reduced comfort.
