Abstract: Assembly of a rim and of a flexible adapter, intended to make up, with a tyre, a rolling assembly. The rim having a mounting well that is extended axially by a boss, a rim seat and a rim flange that extends the rim seat axially on the outside, with a bearing face of substantially radial orientation. The adapter having an axially inner end intended to rest on the rim seat, an axially outer end and a substantially cylindrical body that connects the axially inner end and the axially outer end and is intended to receive, in cooperation with the axially outer end, a tyre bead. The rim seat of the rim has an inclination relative to the axis of rotation of between ?2 and +6 degrees, the angle being counted as positive when the virtual vertex of the substantially frustoconical seat is situated axially on the outside.

Abstract: A hubcap for a wheel with a floating tire seat, the wheel having a rim comprising a tire seat extended axially outwards by a flange, the tire seat being radially floating, comprises a central edge and an exterior periphery, in which the central edge comprises fixing elements for attaching to the rigid part of the wheel and in which the central edge is connected to the exterior periphery by an intermediate sector that is deformable so that the exterior periphery can be moved at least radially inwards with respect to the central edge.

Abstract: Hubcap (1) for a wheel (2) with a floating tyre seat, the said wheel (2) having a rim comprising a tyre seat (253) extended axially outwards by a flange (254), the tyre seats (253) being radially floating, the said hubcap comprising a central edge (11) and an exterior periphery (12), in which the said central edge (11) comprises fixing elements for attaching to the rigid part of the wheel and in which the said central edge (11) is connected to the said exterior periphery (12) by an intermediate sector that is deformable so that the exterior periphery (12) can be moved at least radially inwards with respect to the central edge (11).

Abstract: Assembly of a rim (3) and of a flexible adapter (1), intended to make up, with a tire (2), a rolling assembly, the rim (3) having a mounting well (33) that is extended axially by a boss (34), a substantially frustoconical rim seat (31) and a rim flange (32) that extends the rim seat (31) axially on the outside, with a bearing face of substantially radial orientation, the adapter having an axially inner end (10) intended to rest on the rim seat (31), an axially outer end (11) and a substantially cylindrical body (12) that connects the axially inner end (10) and the axially outer end (11) and is intended to receive, in cooperation with the axially outer end, a tire bead (21), characterized in that the substantially frustoconical rim seat (31) of said rim has an inclination (?) relative to the axis of rotation DD? of between ?2 and +6 degrees, said angle (?) being counted as positive when the virtual vertex S of said substantially frustoconical seat is situated axially on the outside.
