A vehicle wheel having a one-piece rim and being provided for a pneumatic belted tire. The seats for the tire beads are located on the radially inner surface of the rim. In order to assure trouble-free emergency operation of the tire in the event of damage or a defect, on the rim and/or on the tire, structures are provided which, at least in the region of the support surface of the tire, effect a disengagement of the tire beads from the rim seats during a loss of air pressure, and which prevent an only periodic return of the tire beads to the seats while driving.
