Abstract
A bead loosening tool for loosening the axially inner bead of a tire in a dual wheel set without disassembling the set and a method of bead loosening for loosening the axially inner bead of such tires. The apparatus includes a pair of elongated arms movable between open and closed positions. In the closed position, the arms are sufficiently close to each other as to be insertable in the space between the tires of a dual wheel set. A motor is provided for driving the arms apart to loosen the bead. According to the method, the tool is inserted between the tires of a dual wheel set and relatively movable surfaces of the tool positioned against the rim of the axially inner wheel of the set and the tire wall adjacent the bead of the axially outer tire in the set. The surfaces are then moved apart to achieve bead loosening.
