The process of separating the tire bead from the wheel rim is a necessary step in tire removal. The bead is the edge of the tire that sits tightly against the rim, creating an airtight seal. Disrupting this seal is essential before the tire can be fully removed from the wheel. This action is commonly required for tire repairs, replacements, and other maintenance procedures.
This separation is crucial for various reasons. Without it, accessing the inner tube (in applicable tires) or the inside of the tire for repairs is impossible. Proper execution also minimizes the risk of damaging the tire or the wheel rim. Historically, specialized tools and techniques have been developed to accomplish this task efficiently and safely, evolving from rudimentary methods to more sophisticated mechanical and hydraulic devices.
