Well it's not actually changed yet but so far so good, I've managed to break the bead and get the old tire off with minimal effort and damage.
My rims aren't pretty so I figured I haven't much to loose and wanted the experiance. I can see why it's easy to really mar a decent set of rims tho.
Oh and clamping the tire to break the bead works like crap, but the clamp came in handy...

I'm planning on balancing the tires myself as well, where can I buy wheel weights?
