ABSTRACT:
A portable or field type tire bead breaker tool comprised of a body member, a jaw member and a bead breaker member where the body member and jaw member are actuatable to bring wedge elements on the body member in position between a tire wall and a tire rim wall proximate to a tire bead. The bead breaker member has a wedge shaped element which is initially disposed in a first position in alignment with the wedge elements on the body member for disposition with the wedge elements between a tire wall and a tire rim wall. The wedge shaped element is arranged to be pivoted independently of the wedge elements to a second position and displace the tire bead from the tire rim. The wedge shaped element thereafter is movable laterally and rotatively to a third position for displacing the tire bead entirely from the tire rim.
