My friend got one of those tire changers and I almost got one and seen the price and thought BS I have stuff in the back yard i will make my own. I made it with a twist on top also and then thought WHY would I want to lift the tire up that high. So i made mine where you set the tire on the steel platform and break the bead. The steel plate on the bottom is wide and long enough you can stick the far end under a car tire or trailer tire to hold it down keep it from tipping over when you apply pressure to break the bead. Angle iron for the struts never bent this one and have removed some rusted on tires with it. Notice the holes.... It's adjustable for tiny to very large 48" swampers.
