Whether you are faced with making a repair or just changing tires, this is the tool. On-road and off-road motorcycle tire beads can be easily separated from their wheel with this sturdy cast iron alloy device. As you torque the spreader assembly with a wrench, the two hinged jaws apply even pressure to the tire bead, releasing the tire from the wheel. The Tire Bead Breaker can be disassembled for easier portability. For use on tube or tubeless tires size 160 and smaller, (will not fit most street/sport rear tires). Weighs 5 1/2 lbs.
