I have mine for 20 years now. Bolted to the floor. Changed 100's of tires along with friends that come over and use it.For aluminum wheels I place towels down while breaking them down.Also for the cross to secure it on top. Next is duct tape on the rim so the bar won't scratch the lip.Silicone spray the heck out of the tire and tool so it slides on the duct tape.Guys with lite weigh race wheels love it.Less chance for bending the rim that a pneumatic may do.
