Abstract

A vehicle wheel having a rigid wheel rim upon which a pneumatic belted tire is mounted. The beads of the tire contain pull-resistant cores, and are secured by a wheel flange against sliding laterally from the seating surfaces. A recess for receiving a tire bead during mounting of the tire is located adjacent to the seating surface on that side facing the rim middle. The seating surfaces are arranged on the inner periphery of the rim adjacent to a radially inwardly extending wheel flange. The base of the recess has a larger diameter than do the seating surfaces. The mantle surfaces of the rim adjacent to the recess are essentially even or smooth supporting surfaces for the tire zenith or crown portion during emergency operation of the tire. The middle portion of the rim, between the mantle surfaces, is also embodied at least partially as a supporting surface for the tire zenith portion during emergency operation of the tire, and the supporting surface lies essentially at the level of the mantle surfaces.
