ABSTRACT:
A device for breaking the beads of a tire, such as a farm tractor tire, from the bead seat on a rim, has a pair of jaws that clamp along the edge of the rim, with one jaw forming claws that pry between the tire and the outer flange of the rim. The jaws are clamped in place on the rim, and a pusher member is mechanically, directly actuated through a screw to push the tire substantially transversely to the plane of the rim to push the bead off the rim seat. Mechanical operation is provided, and because the pusher member can be directly operated a substantial force urging the tire bead off the bead receiving seat surface can be generated without having the device slip off the rim.
