Abstract: Disclosed herein is a tire repairing tool used exclusively with a semi-drop type safety wheel comprising substantially a base member having an upstanding bar which traverses through an open portion of a wheel rim of the semi-drop safety type in which the bottom portion of the base is provided with a stay member to constrain the wheel rim during the tire removal operation. The upstanding bar member coacts through a hook inserted in an opening at the top most extremity thereof with this hook providing a hinged lever point to allow insertion therethrough of a chisel connected to a lever arm through a linkage system. Shims are provided between the upstanding bar of the base member and the chisel to nest against the wheel disposed on this type of wheel and constrain it from any motion during the tire working process.
