A rolling assembly comprises a tire (2) having two beads (21), a rim (3) and at least one flexible extender (1) intended to provide the connection between one of the beads (21) and the rim (3), the rim having a rim flange (32), said extender (1) comprising an axially inner end (10), an axially outer end (11) and a body (12) that is oriented mainly axially and is disposed between said axially outer end (11) and said axially inner end (10), said axially inner end (10) being fixed in place on said rim, said extender (1) having an extender seat (13) intended to receive a tire (2) bead (21), said extender seat being extended axially towards the outside by a shoulder that axially fixes said tire (2) bead (21) in place, said tire (2) bead (21) having an axial width WB at the interface of the bead (21) with the extender seat (13), characterized in that said rim flange (32) extends axially under the bead (21) by a distance S such that the ratio S/WB is greater than 0.1.

An annular and ring extends around the interior of a wheel/rim on which a tire is mounted. The inner diameter of the annular ring is sized for a snug fit on the wheel rim. A tensioning cable extends through the tubular ring and opposed arms are attached to the ring and are movable between disengaged and engaged positions. The apparatus is selectively movable by actuation of a cable tensioner between a first, disengaged position where the arms do not engage the tire and thereby lock it to the rim, and a second, engaged position in which the arm bear against the tire beads, capturing the tire beads between the rim flanges and the wing members to lock the tire to the rim and to create and/or enhances the air-tight seal between the tire and the rim. The bead lock apparatus may be beneficially used in combination with a foam insert for enhanced tire performance.

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.
