Description

Wear-resistant explosion-proof tire Technical Field The utility model relates to the technical field of tires, in particular to a wear-resistant and explosion-proof tire. Background The tire is a core component for the contact between the vehicle and the ground, directly affects the running performance, the safety and the fuel efficiency of the vehicle, has the core value of providing good grip, wear resistance and comfort by optimizing the tread design, the material selection and the structural layout, however, along with the continuous improvement of the requirements of the automobile industry on energy conservation, environmental protection, intelligence and high performance, the traditional tire has a plurality of challenges in terms of material performance, structural design and functional integration. The anti-explosion tire is designed by adding additives such as net-shaped steel wires, twines and the like into a rubber tire blank in the manufacturing process so as to increase the tensile capability when the tire tread is damaged, when the tire is subjected to penetration of foreign matters or extremely strong impact force, the local pressure is extremely high due to extremely small stressed surface, under the condition, the supporting force of the rubber tire tread is insufficient to resist the external pressure, the anti-explosion effect is poor, after the tire is penetrated or is subjected to serious impact, internal air is rapidly leaked, the tire can rapidly collapse, the supporting force of the tire is rapidly reduced, the weight of the tire cannot be continuously supported, the vehicle cannot continue to run, the conventional tire can be contacted with the ground for a long time to generate friction, and the common tire is usually prevented from slipping by virtue of patterns on the tire tread after long-time use, most patterns on the tire can be directly contacted with the ground due to the fact that the tire surface of the tire is easy to cause the patterns to be damaged, the phenomenon that the tire is easy to slip is easy to cause the tire to slip phenomenon due to the fact that the tire friction is easy to occur, and the anti-skid effect is seriously influenced when the tire is used.
