The separation of a tire’s inner edge from the wheel rim, commonly referred to as bead breaking, is a fundamental step in tire removal and replacement. This process overcomes the tight seal between the tire and the rim, allowing for safe and efficient tire servicing. For instance, when replacing a worn tire or repairing a flat, initiating the service requires this separation.
Successfully executing this procedure is crucial for both professional mechanics and individuals performing their own tire maintenance. It ensures the rim is not damaged during tire removal and simplifies the subsequent steps of mounting a new tire. Historically, specialized tools have been developed to facilitate this task, evolving from simple manual levers to sophisticated hydraulic devices that minimize physical exertion and maximize safety.
