A tire changer isa great investment, swap a few sets and it pays for itself. I just needed a few extras withthe HF one to ensure that I wont scratch the rims. The first couple I dinged up prety good ( they were my rims and I didnt care) but once I got the hang of it I can swap them and not a worry about a scratch.
