Abstract: The invention is directed to a tire and wheel rim assembly for a vehicle. The tire comprises a pair of bead regions each reinforced by a bead core characterized by at least one bead portion of the tire having an additional hardened retention zone positioned axially inwards of and integral with the main bead portion, the retention zone having an axially inner tip or toe substantially inwards of the main bead portion and the construction of the bead between the bead core and tip providing substantial resistance to compressive forces therebetween. The wheel rim comprises a pair of bead seats and axially inwards of and adjacent to at least one of the bead seats, which is that part of the bead seat contacted by a standard tire, at least one circumferentially extending tooth having a sharp edge inter-engaging only the retention zone of the tire at the tip such that when lateral force is applied to the tire tread and internal inflation pressure is low, axially inward movement of the tip is resisted by tip-to-tooth inter-engagement thus causing bead rotation about the tip and generation of compression force in those parts of the bead region between the tip and the core to provide bead retention at the bead seat. The invention also provides a wheel rim and a tire having the above features.

Abstract: The present invention relates to a radial tire and a radial tire-rim assembly. The radial tire (1) has a pair of beads (2), each bead having a bead core (3) and a bead apex (5), a carcass (4), with both edges thereof folded back around said bead core and fastened to said bead core, a tread (6), a belt layer (7), and an aspect ratio smaller than 60%. The tread is wider (in the axial direction) than the maximum width of said carcass and the edges of said tread are positioned within a range of 50-100% of the height of the cross-section of the carcass. This structure provides the tire side with rigidity and permits the tread to deform so that it supports the weight of the car and runs safely even when the tire pressure is decreased. The radial tire-rim assembly is characterized in that the bead of the radial tire has a toe (9) extending inward (in the radial direction of the tire) and is further provided with a hump groove (10). Correspondingly, the rim (20) has an annular groove (22) and hump (23) which fit into the toe and groove, respectively. These arrangements prevent the bead from separating from the rim when the tire pressure is decreased or at a time of sharp cornering.

Abstract: The pneumatic tire is designed particularly to counteract unwedging of the tire. It is mountable on a rim having a protrusion (referred to as "hump") of ordinary shape. The bead has two bead rings, one of which is close to the bead tip while the other assures the blocking of the former in case of strong axial forces, which permits the bead tip to cooperate more effectively with the hump of the rim.

Abstract: A method for the manufacture of a pneumatic tire and wheel assembly comprising welding a rim having a circumferential well portion to a wheel body portion at a position on the rim on or adjacent one flank of the well portion. A pneumatic tire is mounted on the rim by a method employing the well portion to enable the tire beads to pass over a rim flange, and subsequently at base the well portion of the rim is subjected to axial compression so as to reduce the axial width of the well portion.
