KoolStop Kool-Stop Tire Bead Jack

The Kool-Stop Tire Bead Jack is an articulated tool, with a comfortable grip, for installing really tight tires. The articulated end uses the rigid piece against the rim edge as a fulcrum while the hinged end lifts the bead up and over the opposite edge of the rim. This is a great tool for dealing with difficult tires – especially those ultra narrow 18×1 and 20×1 tires that leave your hands aching for days every time you change them.
