A device for serving as a wheel for motor vehicles, where the wheel has its tire tread replaceable when it is worn out via unique rims and molded tire features. An alternate internal structure prevents the tire from “going flat” or “blowing out” when it is punctured or cut. In one variation the tire can be used with existing rims and can be retro-fitted into existing tire by mating the tires with this invention's “Non-Flat Tire” internal element and special rim. A variation of the “Non-Flat Tire” system uses spring-like materials for its tire core that is shaped similar to a tire's inner tube, and functions like an “air-filled” tire, but the absence of the use of air in this unique configuration gives it the “Flat Tire Prevention” effect.
