Wheel with rim embraced by tire
First Claim
1. A wheel comprising a central disc portion adapted for attachment to a vehicle, a pair of substantially continuous circumferentially and substantially axially extending tire bead seating surfaces which face radially outwardly, one for each of a pair of continuous beads of the two sidewalls of a tire, a pair of radially outwardly projecting bead locating flanges axially inboard of said seating surfaces, with each flange being adjacent to the inboard edge of a continuous bead of a tire when mounted on the wheel, said seating surfaces and said flanges being the only means retaining the tire bead to the wheel and means to force at least said flanges away from each other after a tire has been mounted with its beads on said seating surfaces, to permit the beads to be forced axially apart while they remain on said seating surfaces.

Abstract
A wheel for use with a tire whose sidewalls are to be maintained in a mechanically compressed condition when it is mounted on the wheel comprises a central disc for attachment to a vehicle, a pair of circumferentially extending radially outwardly facing seating surfaces for each of the radially inward ends of the sidewalls of a tire and a pair of radially outwardly projecting flanges axially inboard of the seating surfaces. Means is provided to force the flanges away from each other after a tire has been mounted on the wheel with its radially inward sidewall ends on the seating surfaces, thereby to force the ends of the sidewalls axially apart while they remain on the seating surfaces.

7. A wheel comprising a central disc portion adapted for attachment to a vehicle, a pair of circumferentially extending radially outwardly facing seating surfaces, one for each of the radially inward ends of the two sidewalls of a tire, a pair of radially outwardly projecting flanges axially inboard of said seating surfaces;
- the seating surfaces and flanges being formed in the projections of a pair of rigid circular plates, the edge of each plate being castellated and the plates being arranged together such that the projecting castellations of one plate extend through the spaces in the other plate such, that when the plates are moved together, the seating surfaces and flanges formed in the castellations are moved apart to permit the ends of said sidewalls to be forced axially apart while they remain on said seating surfaces.
