Causing great property economic loss to people, and therefore, the flat tire is considered as the first killer of the expressway. When the vehicle blows out, the binding force between the tire and the hub is lost instantly, even the tire is directly separated from the hub, so that the vehicle loses balance at high speed, and a traffic accident is caused.

At present, the most practical run-flat tires in the prior art all adopt a sidewall reinforcement technology, and the run-flat tires are used in small-sized automobiles. In the technology, the reinforcing layer with higher hardness and strength is arranged in the tire side wall, and the reinforced tire side wall supports the tire to continuously run to a maintenance station for replacing the tire after the tire is deflated, so that a driver does not need to take a risk to replace the tire on a road, a spare tire can be omitted, and the weight of an automobile is reduced. However, the described sidewall reinforcement technique has the following significant drawbacks: 1. the danger that the tire may fall off the hub when the side wall reinforced tire runs after air leakage is not completely eliminated; 2. because the side wall reinforcing layer with higher hardness and strength is arranged, the comfort and the heat radiation performance of the tire are reduced; 3. the reinforced tire sidewalls make tire installation difficult, requiring the use of expensive specialized tire installation equipment; 4. the sidewall reinforcing layer is made of expensive high heat-resistant synthetic rubber material to reduce the influence of the above problems, and the cost of the tire is about 3 to 5 times that of a conventional tire, and the cost of replacing the tire is high.
