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.
