Explosion-proof tyre for mountain lorry

Technical Field

The utility model discloses an explosion-proof tire for a mountain truck, and belongs to the technical field of tire products.

Background

The tyre is a tyre body with a circular elastic rubber product structure, and the tyre body is usually arranged on a metal hub, can support a vehicle body, buffer external impact, realize contact with a road surface and ensure the running performance of the vehicle. Tires are often used under complex and severe conditions, and they are subjected to various deformations, loads, forces and high and low temperatures during running, and therefore must have high load-bearing, traction and cushioning properties. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat buildup. Conventional pneumatic tires often suffer from flat tires, are over-inflated, under-inflated, have cracks, or are directly pierced, and in order to avoid accidents during running, it is necessary to frequently check the wear level of the tread and detect the tire pressure and temperature information. In the actual running process of the automobile, the automobile tire is easy to burst due to external factors, and once the automobile is burst, the automobile is out of balance, so that serious safety accidents are generated, the existing automobile is lack of a protection device for the automobile tire after the tire burst, and therefore the accident generated after the tire burst of the automobile is extremely harmful to personnel. Particularly, the automobile tires are easy to burst under poor road conditions and high-speed running of the automobile, so that the dangerous situations such as out-of-control and the like of the automobile are easy to cause, and the life safety of drivers and passengers can be endangered.
