An agricultural tool includes a wheel body and a flexible tyre with a hollow chamber and an inner surface around this hollow chamber; a circular opening on the chamber; a pair of beads bordering this opening; and a spacer at least partially tubular with two axially opposite end faces. Over one portion corresponding to one of the beads, the inner surface extends frustoconically by widening radially outward of the flexible tyre, and one of the end faces of the spacer has an axially protruding surface. The spacer is placed across the opening of the tyre such that the protruding surface engages the inner surface in an area of the portion corresponding to the bead.

A wheel assembly is provided. The wheel assembly includes a rim configured to receive a tire of an off-road vehicle. The wheel assembly also includes a flange member slidably received on the rim. The flange member has a flange portion with a terminal end defining a first axial extent of the flange member. The wheel assembly also includes a locking ring radially and axially interposed between the rim and flange member. The wheel assembly also includes a locking arrangement mounted between the rim and the flange member which has a second axial extent. The second axial extent is substantially axially adjacent to the first axial extent.

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.
