    Abstract: A vehicle wheel has a pneumatic tire mounted thereon. The wheel has a rigid rim having essentially radially inwardly extending rim flanges and, on the radially inner side of the rim ring, the rim has respective mounting spaces, each with a deep mounting bed. The pneumatic tire is provided with tire beads having a cross-sectional form which, on the one hand, permits the tire bead to extend into the mounting space and deep bed during mounting, in which, on the other hand, closes-off the mounting space and deep bed when the tire is in its operational state. In order to disconnect the tire seat from the rim support surfaces, it is proposed that the deep mounting bed extend directly to the rim flange, and that, in the operational state of the tire, on the one hand the tire bead be spaced from that portion of the rim ring that is adjacent to the rim flange, and on the other hand a portion of the tire bead butt axially inwardly against a portion of the rim.

  • Patent number: 4662418
    Abstract: A vehicle wheel has a wheel body or hub, an annular rigid rim mounted on it and an elastic inflatable tire mounted on the rim, the beads of the tire engaging annular recesses present on the inner face of the rim. The rim is provided with side flanks of the same curvature matched to the curvature which the flanks of the tire take up in operation, and between which is provided an annular engaging surface extending over the whole width of the rim from flank to flank, this surface giving the wheel good emergency characteristics. The inserts in the beads of the tire do not need any thickened beads which would adversely affect the resilience of its side walls, but only need to be made constructionally and to hold the reinforcing cords. The rim is made in one piece of a light material such as plastics or aluminum and can form an air reservoir for compressed air which is under high pressure and which automatically replenishes the tire when needed.
