Abstract:
A rim for mounting a tire having at least two beads, which rim is defined axially on one side by a first rim edge and on the opposite side by a second rim edge, comprising, viewed in meridian section, a first rim seat axially adjacent said first rim edge and a second rim seat axially adjacent said second rim edge, at least the first rim seat having a generatrix, the axially inner end of which is on a circle of diameter greater than the diameter of a circle on which the axially outer end is located,and at least one bearing surface, of axial width Lp, intended to receive an annular bearing support by sliding said support over at least said one side of the rim, said bearing surface being arranged between the axially inner ends of the two seats and having an essentially cylindrical shape of minimum development Dp at least equal to the development of any rim part located axially between the axially inner end of the first rim seat and the first rim edge, wherein: the bearing surface comprises at least one surface clamping part, each surface clamping part being regularly distributed in the circumferential direction over said bearing surface and having a maximum external development Ds greater than Dp, said development Ds being measured on an enveloping surface concentric to the bearing surface, in order to create mechanical clamping when a tire support ring is mounted between said ring and said surface clamping part, which mechanical clamping is appropriate to ensure holding of said ring on the bearing surface.
