A wheel assembly for a tire includes a circular hub member for securing to a rotatable axle of a vehicle, a first rim piece for engaging the hub member, a second rim piece for engaging the first rim piece, and a plurality of cylindrical sleeves for engaging both the first rim piece and the second rim piece. The first rim piece has cylindrical first shafts each engaging a first end of one of the sleeves. The second rim piece has cylindrical second shafts each engaging a second opposite end of one of the sleeves. An outer cylindrical surface of each sleeve engages a separate and distinct part the tire.

A rim (3) for a rolling assembly has a flexible extender, the rim having an axis of rotation DD′, said rim having a rim seat (31) extended axially towards the outside by a rim flange (32), said rim flange (32) having a first portion (321) that is oriented substantially in a plane perpendicular to the axis of rotation DD′ and situated radially on the outside with respect to said rim seat (31), said first portion (321) being extended radially and axially towards the outside by a connecting portion, characterized in that the radial height measured between the intersection point between the line of the rim seat and the line of the first portion, and the end of the radially outermost portion of the rim flange (32) is less than 10 mm.

A wheel rim assembly and components, systems, and methods thereof can comprise a rim base having at least one slot at an outer end portion thereof, a bead seat band radially outward of the outer end portion of the rim base, and at least one lock provided in the at least one slot. The bead seat band may be in direct contact with the outer end portion of the rim base. The lock can have a first portion that is provided in the slot of the rim base and a second portion that is outside of the slot. The second portion may be adjacent to the bead seat band. The wheel rim assembly may be free of or without a lock ring at the outer end portion of the rim base.

A dual wheel adapter assembly for mounting dual wheel rims to a wheel hub is provided. The dual wheel adapter assembly may include a hollow cylindrical adapter, including a central bore defined by an inner surface of the adapter, a first contact surface, and a second contact surface. The dual wheel adapter assembly may also include an inboard wheel rim configured to support a tire, an outboard wheel rim configured to support a tire, and a wedge clamp configured to be coupled to the hub. The first contact surface may abut the hub and the wedge clamp may apply a compressive force to the second contact surface to couple the adapter to the hub.

Adapter for a rolling assembly comprising a tire, and a rim having two rim seats and two rim flanges. The adapter has an axially inner end mounted on the rim seat and comprises an inner reinforcing element, an axially outer end that comprises an outer reinforcing element, a body that connects the two ends to form a single piece. A substantially cylindrical adapter seat is configured to receive a bead, and is situated at the axially outer end of the body. An adapter bearing face is substantially contained in a plane perpendicular to the rotation axis, and situated on the axially inner face of the axially outer end. The reinforcing element of the axially outer end is entirely situated axially outside the bearing face. The body comprises, opposite the adapter seat, an annular seat reinforcer. The inner wall of the tire is covered by a layer of a self-sealing composition.
