A vehicle wheel having a one-piece wheel rim on which can be mounted a pneumatic tire. The tire has a tread strip, two sidewalls, a carcass, and two tire beads which are laterally spaced from one another and contain substantially inextensible bead cores. The wheel rim has two rim shoulders, which are laterally spaced from one another and extend outwardly into a respective rim edge or into a respective rim flange. The rim also has a radially recessed rim base. The wheel further includes an emergency operation support member which is disposed in the recessed rim base and has a supporting surface which is located radially outwardly of the rim flange. The emergency operation support member is provided with a radially inner surface which faces the rim shoulder and is disposed at a distance from the latter, this distance corresponding to at least the thickness of the tire bead. An annular chamber is provided which extends further radially inwardly to the recessed rim base, and is widened axially inwardly. |
