Who invented the automobile vacuum tire?

The vacuum tire was invented by Michelin Tire Company of France in 1959. Vacuum tire, also known as radial tire, is composed of a layer of steel wire (belt) around the ply, which improves the strength of the tire, has good heat dissipation conditions and is suitable for high-speed driving; The disadvantage is fear of lack of air. When driving in the absence of air, the tire subsidence increases, the friction with the ground increases exponentially, the tire temperature rises sharply, the tire becomes soft, and the strength decreases. Friction between steel wire and cord fabric in tire also generates heat. Overheating will accelerate the aging, deformation and even internal fracture of steel wire and rubber, and even delamination, which will bury the curse of puncture. Driving at low speed without air will also puncture the tire and puncture the tire side, with long incubation period, stronger concealment and greater harm. It's easy to get a flat tire when driving at high speed in the future.
