Abstract
The vehicle wheel comprises a rim containing an external closed ring and an internal rim ring composed of three segments and connected to a segmentally separated or segment-shaped divided disc. The beads of the pneumatic tire lie in grooves disposed between the external closed ring and the internal rim ring. Each of these grooves is formed by a bead seat, a vertical web and the external closed ring. Due to the internal pressure of the air in the pneumatic tire, each tire bead is drawn against clamping surfaces of the associated groove and sealed in relation to the external closed ring.
