A simple tool to make a hard job easy. To quote the late Sheldon Brown
"Some tire/rim combinations are just too tight a fit, and you may need to use a tool. The best tool for this is the Kool Stop bead jack because this tool lifts the edge of the tire without going inside of it, so it is less likely to damage the inner tube than a conventional tire lever is. "
