Effects of the Invention As explained above, in the wheel tire puncture prevention device according to the present invention, a large number of synthetic resin unit protection pieces having stepped protection walls are attached to a flexible and bendable support member. Since they are attached to each other in a mutually interlocking and overlapping manner so that they are supported independently on the outer circumferential surface, each unit protection piece and support member flexibly bends due to any impact applied to the puncture prevention device. As it is deformed, it completely blocks all needle-like hazards from entering the tire from outside, and has the effect of completely preventing tire punctures or ruptures. In addition, even when subjected to any impact while driving, the tire's basic shape is normally maintained due to the flexible bending and quick restoring elasticity of the puncture preventive device, and the effect is that the unique performance of the tire and the running performance of the wheel can be stably maintained. be. In addition, by variously changing the specifications and shapes of the support member of the puncture prevention device and the unit protection piece attached to this support member, it can be applied to tubeless tires, tube-type tires, motorcycles, bicycles, etc. It has a wide range of effects that can be applied to all wheels.
