I've known guys to use furniture clamps to break beads. I've seen guys step on them and break them loose. I know one guy that carried his off to a school playground and used a 'teeter-totter' to break his bead. This works for me.
Very straight forward. Very simple. And it works. I changed out a 180/55R-17 and a 180/70R-17 off mags without issues a week ago. Notice the multiple holes in the riser - that is your tire width adjustment. Customeize your spacing for your needs. Crib up the bottom side of the tire in both places where it rests on the deck with small blocks of 2x4 - and pay attention that it will not hit your rim. Press down slowly until the side walls squeeze together and meet; turn 90 degrees and repeat. The bead will break loose. Then it's rim protectors and tire levers to get the old rubber off the rim. Clean the inside of the rim thoroughly. Best practice is to replace the valve stem. Lever on the new rubber making sure the rotation arrow is corrrect. Balance and re-install. Balance? That's another article in the works.
