ABSTRACT:
A pneumatic tire for a vehicular tire and wheel assembly that includes a rigid wheel rim, which is provided with essentially radially inwardly extending rim flanges, rim seating surfaces disposed on the radially inner side of the rim ring and inclined in the transverse direction, and a recessed mounting bed for each tire bead, and that also includes a pneumatic tire of elastomeric material, with bead seating surfaces of the tire beads being disposed adjacent to the rim flanges on the rim seating surfaces, and with the carcass of the tire being anchored in the beads by being looped about pressure-resistant bead cores. In order despite manufacturing-related tolerance differences of the rims and tires to obtain an improved bead seating, each bead is provided with recesses disposed therein in such a way that when the tire is mounted on the rim and inflated to the operating pressure, a base portion of the bead that rests against the rim seating surface exerts thereon a compression pressure in the range of from 8 to 56%.
