Britman the only reason I change my own tires on my T120 is that I don't have anyone willing to get that DIRTY! :lol: :lol: The rear tire on the '70 Bonnie is the dirtiest job that every existed. I can't imagine trying to change a modern tire with tire irons and curses. For sure you can't do the rear that way, the center of the tie is too shallow, the tire doesn't slip in like normal. The front maybe? I would pay someone with a machine. I'm even a little nervous when I think of taking the wheel off the big beast.
