Bead breaker for tubeless tires |
摘要 |
A tool for breaking a tire bead away from a wheel rim and shoulder has a lever in the form of an elongated plank provided with a hook and a breaker that are wedged between the bead and the wheel lip in diametrically opposed relationship when a force is applied to the lever. The breaker is swingable on the lever plank such that when it is swung open the plank is disposed in an inclined, ramp-like manner permitting a wheel of a vehicle to be driven along the plank. After the breaker closes against a stop the tire casing is compressed, causing the bead to move downwardly along the rim away from the shoulder until the bead is effectively broken permitting tire removal.
