Designed to push the tyre bead down into the drop centre of the rim without fighting while installing or repairing your off-road tyres/tubes. The nylon thumbscrew keeps rims from being scratched when in use. Constructed from 6000 series aluminium. It will facilitate pulling the tyre over the edge of the rim allowing for easier and faster tyre removal and installation. No more fighting to keep the bead down while installing off-road tyres.
