An improved clamping mechanism to secure a tire between a bead ring and a wheel utilizing a bolt is provided. The bolt has a ball seat that pivots within an enlarged pilot hole in the bead ring as the bolt threads engage in threaded section of the wheel, pulling the bead ring toward the wheel. As the bead ring is tightened upon the wheel, eventually the bead ring contacts a fulcrum on the wheel, at which point the outer edge of the bead ring is leveraged against the tire bead bundle and pressing down the tire bead to lock it in place against the wheel. As the bead ring can pivot within the enlarged pilot hole around the bolt, the bolt is not stressed. Further, the wheel comprising a safety bead and non-skid coating on the inner wall of the wheel to prevent the wheel sliding around the wheel.

A rim for a tire for means of displacement preferably for heavy loads at low-speed. The rim may include a main tubular body having a cylindrical surface extending between two lateral edges, a bead-seat having a greater diameter than the cylindrical surface of the tubular body and overlapped to it and at least a side-ring being overlapped to one of the lateral edges for the lateral containment of the tire. The rim may include compensating means interposed between the cylindrical surface of the tubular body and the bead-seat and in contact with them to realise a compensation in thickness.

The rolling assembly has a rotation axis and comprises a rim having two rim seats that is axially outwardly extended by rim flanges, one adapter and a tire having two beads. The adapter provides the connection between one of the beads and the rim and comprises an axially inner end that is adapted to be mounted on one of the rim seats, an axially outer end that is adapted to receive one of the beads and an adapter body connecting the axially inner end and the axially outer end as to form a single piece. The two rim seats of the rim have different diameters with a gap D. The adapter is mounted onto the rim seat having smaller diameter. The rim seat of the rim has a smaller diameter positions on a side intended to be inside when the rolling assembly being mounted onto a vehicle.

A wheel rim for a vehicle including a first rim portion including a first wheel flange, a second rim portion threadedly connected to the first rim portion, and a second wheel flange held on the first rim portion.

An apparatus and methods are provided for a bead-locking wheel for mechanically coupling a tire to a wheel rim of an off-road vehicle. The bead-locking wheel includes a barrel for mounting the tire and a bead lock face for fastening the barrel and tire to a wheel hub of the vehicle. The bead lock face is fastened to a shoulder disposed around an outboard end of the barrel. The shoulder and an outboard flange of the barrel cooperate with a periphery of the bead lock face to mechanically retain an outboard bead of the tire. Mechanically retaining the outboard bead facilitates a relatively low inflation pressure within the tire to accommodate off-road conditions and high tractive forces. The bead lock face maximizes a positive offset and backspacing of the bead-locking wheel to accommodate a relatively wide hub and spindle assembly while maintaining an advantageous steering geometry and track width.

The rolling assembly has a rotation axis and a rim having rim seats and flanges, an adapter and a tire having beads. The adapter provides the connection between one of the beads and the rim. The rim comprises a portion of a width W extending outwardly from the flange and a connecting introduction portion and a body. The body has a point A that is 10% of W axially inward from an axially outermost of the body or from an axially outermost of the adapter. The portion creates a virtual straight line GD between an innermost of the connecting introduction portion and the point A. The portion and the adapter has a radial distance d at the point A. The body has a maximum radial distance e from the virtual straight line GD at axially inward from the point A, and the body has no contact with the adapter.

A wheel assembly includes a first side plate having a first annular base, axially protruding first claw members projecting axially outward from the first annular base, axially protruding first hub mounts projecting axially outward from the first annular base, and axially protruding first spring mounts projecting axially outward from the first annular base; a hub member attached to the first side plate; and a tire assembly laid over the hub member such that spokes of the tire assembly are radially adjacent corresponding first claw members of the first side plate, a plurality of friction members and the first claw members sandwiching each of the spokes.
