Bullet-proof and leakage-proof security upgraded tire as well as manufacturing method thereof

The invention relates to a bullet-proof and leakage-proof security upgraded tire as well as a manufacturing method for upgrading a common tire into a bullet-proof and leakage-proof security upgrade tire. The method is characterized by spraying a layer of macromolecule self-sealing material on the inner wall of a common vehicle tire so as to form a bullet-proof and leakage-proof security automatic sealing layer, thereby forming the bullet-proof and leakage-proof security upgraded tire. The vehicle tire has bullet-proof and leakage-proof security performances, and is suitable for military vehicles and civilian vehicles. The manufacturing method is suitable for tire upgrading of existing military vehicles and civilian vehicles, the safety hazards of tiny air leakage of vehicle tires and air leakage caused by piecing by sharp substances are overcome, the maintaining cost of vehicle tires is reduced, the running security of vehicles is improved, terrible traffic accidents are reduced, and the tire and the method have potential military benefit and social benefit, as well as obvious economical benefit.
