ABSTRACT:
The tire mounting tool for use in mounting a large, heavy off-highway pneumatic tire onto a dual-flanged single piece drop center wheel rim of the type having at each rim flange a re-entrant lip protruding radially inwardly toward the axis of the rim. The tool has a main frame adapted to be placed upon one side of the wheel rim when the rim is resting horizontally. The frame is longer than the inside diameter of the rim flange lip and slidably rests thereupon, and also slidably grips the rim lip and is bodily rotatable about the wheel axis. A pair of arms each are pivoted at their inboard ends to the main frame at a common pivot point for pivotal counter-rotational movement on opposite sides of the main frame about a pivot axis parallel to the rim axis. A pair of tire-bead-engaging shoes are carried one on each of the outboard ends of the arms. A pair of hydraulic rams are interconnected one between each of the arms and the main frame for counter-rotating the arms. The rams are operably interconnected for fluid pressure actuation in a parallel fluid circuit from a common hydraulic pressure fluid source.
