A tire-wheel assembly comprising:
- a wheel coupled to a rotating shaft;
- an elastic tube disposed on an outer side of the wheel in a radial direction, an interior of the tube being filled with air;
- a rigid protective ring disposed on an outer side of the tube in the radial direction so as to be separated from the wheel;
- and
- a tread ring disposed on an outer side of the protective ring in the radial direction, an inner circumferential surface of the tread ring contacting an outer circumferential surface of the protective ring.
An annular tread ring formed from an elastic member, and comprising an inner circumferential surface that contacts a ring-shaped rigid member and an outer circumferential surface that contacts ground, the tread ring comprising:
- through-holes formed in the tread ring that penetrate from the inner circumferential surface to the outer circumferential surface.
