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.
