The tire encloses a torus-shaped hollow body in foam material (18) which is reversibly deformable and includes closed, gas-filled pores (18a). Preferred Features: The foam torus is fastened to the rim (12). It is enclosed in a tire tube fastened to the rim. When pumped up, the toroidal foam body seats in the base of the rim (12a). It is so dimensioned that an intermediate space (19) containing compressed air remains between the tread and the foam insert. |
