Whether tractor, combine, truck, wagon, or ATV tire, the portable Bead-Cheata Tire Bead-Breaking Tool eliminates the need to remove the wheel to change a tire, including one with heavy counterweights. One of the tool's tongues locks under the rim, while the other two push the bead into the wheel well. (The tongues are forced into position with a hammer used on the built-in strike plate.) A series of adjuster screws, combined with a cam-locking device, enable the tool to clamp all types of wheels and rims. Using a 1/2-inch ratchet wrench with 1 ¼-inch socket on the hex head, the tool can generate up to 10 tons of pressure on the bead.
