Abstract

An emergency support member is provided for a vehicle wheel and tire assembly having a pneumatic tire that is mounted on a wheel rim. The support member is embodied as a dished annular member within the tire, and has an emergency support surface for supporting the tire in the event of damage thereto. The annular member extends axially from the center of the rim and symmetrically over a portion of the width thereof. The annular member has a curved contour, with the two axially outer wall regions being supported upon the wheel rim via annular support elements. The dished annular member is embodied as a split ring that is not closed over its periphery, and is provided with a closure device for closing off the slit. The closure device includes two flanges that extend essentially radially inwardly relative to the rim. The closure device also includes at least one locking clamp for connecting the flanges.
