The rotating bead hold-down in the PRO version was developed for the highest levels of stress during the mounting and demounting of stiff tyre beads. Unlike the standard version, a robust screw mechanism ensures extremely firm and slip-resistant clamping on the rim. This enables reliable positioning of the tyre bead beneath the rim flange even under extreme counterforces.

An additional extender included in the scope of delivery significantly extends the functional scope. The extender can optionally be used to press the tyre bead even deeper into the drop centre of the rim. This drastically reduces the build-up of stress in the material, and damage caused by overstretching of the tyre sidewall is effectively prevented even with the most demanding UHP or run-flat tyres. Its use makes manual pressing down or the support of a second person unnecessary, increasing work efficiency in everyday workshop use.

The system is designed for a precise fit with the ATH M74, ATH M72, ATH M52 and ATH M32 tyre changers and, thanks to its universal design, is equally suitable for cross-manufacturer use on other tyre changers.
