Filed: 1984-12-07
Granted: 1989-11-02
Abstract: A vehicle wheel, especially for a truck. The wheel has a rigid rim on which can be mounted a pneumatic tire of rubber or rubber-like material. The carcass of the tire is anchored in the tire beads by being looped around pull-resistant bead cores. The tire beads are disposed on the radially inner periphery of the rim ring. In order to make it particularly easy to mount the tire, the rim seating surfaces for each tire bead extend essentially horizontally in the transverse direction, and extend to the edge of the rim ring. A clamping ring is disposed radially inwardly of the tire bead, with that side of the clamping ring which rests against the bead extending at an angle to the axis of rotation of the wheel. The bead core has a cross-sectional shape which includes sides which extend essentially parallel to the clamping ring and parallel to the rim seating surface.
