As an important component in an automobile driving system, a tire is sleeved on a rim and is the only component on an automobile, which is directly contacted with the ground. In the running process of the automobile, the tire mainly supports the whole automobile, relieves and partially absorbs the impact and vibration borne by the automobile in the running process, ensures good adhesion between wheels and the ground, ensures that the automobile has good traction performance, braking performance and passing performance, and has very important influence on the operation stability of the automobile.

During the running process of a vehicle, the tire is susceptible to various mechanical, electrical, physical and chemical pressure effects and is influenced by various factors such as roads, natural environments and the like, and faults such as tire burst and the like can occur. According to the statistics of traffic accidents in recent years by traffic departments, the traffic accidents on expressways account for 46% of the accidents related to tires, and the accidents caused by tire burst account for 70% of the accidents related to tires (Caocheng, the reason for tire burst and the prevention and treatment measures of automobiles on expressways, 2008,2: 56-57.). At present, the risk of tire burst of the tire becomes the focus of attention, and the problem of tire burst of the tire is urgently needed to be solved so as to increase the safety of vehicle running.
