Breaking a tire bead is the process of separating the tire from the wheel rim. This is necessary when replacing a tire, repairing a flat, or mounting a tire on a new rim. There are a few different ways to break a tire bead, but the most common method is to use a tire bead breaker.
Tire bead breakers are specialized tools that are designed to break the bead of a tire without damaging the tire or the rim. There are two main types of tire bead breakers: manual tire bead breakers and hydraulic tire bead breakers. Manual tire bead breakers are operated by hand, while hydraulic tire bead breakers use hydraulic pressure to break the bead of a tire.
