Rim and assembly of tire and ring-shaped tread support on same
First Claim
1. A rim intended for the mounting of a tire with two reinforced beads, and delimited axially by two rim edges spaced axially apart by the rim width, comprising, seen in meridian section and axially towards the outside, a first rim seat and a second rim seat, at least the first rim seat having a generatrix the axially outer end of which lies on a circle of a diameter less than the diameter of the circle on which the axially inner end is located, the two rim seats having different seat diameters.

Abstract
A tire (1) a mounting rim (2) therefor, and a prop ring (3) for supporting the tread (10) of the tire when running at low or zero pressure. The tire (1) has a radial ply casing (13) on which the points that are furthest apart axially are radially apart close to seats (12B) of outwardly sloping beads (12). The seats (12B) engage sloping seats (23'"'"', 23") on the rim (2), which may have at least one mounting well (22), at least one cylindrical portion (21) for receiving the elongatable and circumferentially unstretchable rubber supporting ring (3) and a rim flange (24).

19. A rolling assembly comprising at least one tire with radial carcass reinforcement anchored in each bead to a reinforcement ring and a rim, delimited axially by a first rim edge and a second rim edge and provided with a first rim seat and a second rim seat, each tire and rim characterized by the fact that, seen in meridian section,
(a) at least the first rim seat has a generatrix the axially outer end of which lies on a circle of a diameter less than the diameter of the circle on which the axially inner end is located, the two rim seats having different seat diameters, and a hump being disposed between the axially outer end of the first rim seat and the corresponding rim edge; - and
(b) the tire, mounted on the rim and inflated to its service pressure, is provided with said radial carcass reinforcement having a meridian profile of constant direction of curvature, at least in the sidewall and the bead which are located on the same side as the first rim seat, the bead seats having different diameters. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
