Abstract: The tread of a tire has an on-road pattern formed in its central area and including traction grooves. An off-road pattern is provided at each side of the tread central area, as formed on each tire shoulder. The off-road pattern has lugs and an annular wing adjacent to a curved recessed portion and is positioned radially inward from the bottom of the traction grooves so as to be held out of contact with the surface of the road during on-road operation. The on-road pattern is immersed in off-road terrain with the off-road pattern in contact with the surface of the terrain over an increased area to effectively engage mud, sand or the like.

Abstract: A sheet coated with beads and comprising a flexible sheet substrate and a transparent bead layer formed on the surface of the substrate integrally therewith, with an adhesive layer provided therebetween. Another bead-coated sheet comprises an elastic flexible sheet substrate, a hard transparent bead layer formed over the surface of the substrate with an adhesive layer interposed therebetween, a transparent cover coat layer integrally formed on the bead layer and a transparent top coat layer integrally formed on the cover coat layer and having lower hardness than the beads. The coat layers permit the bead layer to retain surface projections provided by the beads.

Abstract: A device for dislodging a tire bead from the bead seat of a wheel rim comprises a support member positionable on the upper side of the wheel rim, a pair of engaging pawl portions provided on the support member and engageable with the wheel rim from outside the outer periphery thereof at diametrically opposed positions of the rim for removably fixing the support member to the wheel rim, and a bead pusher provided on the support member adjacent to at least one of the engaging pawl portions. With the wheel rim clamped between the pawl portions at the opposed positions, the bead pusher is driven by rotating a screw to cause the pusher to dislodge the bead from the bead seat and push the bead into the center drop of the wheel rim.
