A component integral to tire changers, this device facilitates the separation of a tire’s bead from the wheel rim. This process is essential for both tire removal and installation. Typically, it involves a lever mechanism applying focused pressure against the tire sidewall, effectively breaking the airtight seal between the tire and rim.
This separation is crucial for efficient tire servicing. Without such a tool, the process would be significantly more laborious and potentially damaging to both tire and wheel. The development of specialized tools like this represents a significant advancement in automotive maintenance, enabling faster and safer tire changes compared to earlier, more rudimentary methods.
