I hate changing tires. More especially, I hate breaking the bead. I went on utube to watch a guy show how to fill a tire with fluid. To break the bead, he made two fists and pushed down on opposite sides of the sidewall. I try standing on the side wall and . . . nothing! Did I mention this was a measly 16x6.50x8? I ended up incorporating an anglegrinder, a large screwdriver, and a 4 lbs. mallet.
