after being annoyed by most bead breakers on the market someone mentioned to me they just use 3 tire irons. 2 pressing down on the tire at 12 and 2 o'clock then the third pressing the opposite direction.
Voila bead popped. I couldn't believe it. I haven't bent over to use the bead popper on any tire change since. Just put the wheel in the wheel holder, 3 tire irons in 3 locations and I'm done.
Try it, you'll be surprised how easy it is. Also, make sure it's well lubed.
