I change my own tires. I use a vise to break the bead,but I think I'll pick up the tool from Harbor frieght. I use a Penzoil can (25gal.?) that gease came in with split ruber hose around the top. A 14" rim will work too. I use 3 tire irons,and have done it solo,but another had helps to mount the tire back on.I balance my wheel with (don't know what the tool is called)whats used to lace wheels. Heavy spot just rolls to the bottom. I do have a few scratches here and there,sometimes I just get a little impatient and hurry through it instead of taking my time with the plastic protectors.
