It works, I tried everything to get a tire rebeaded on my tractor last fall....nothing worked until some local redneck suggested this method, I tried it and problem was solved within 3 seconds
Comes in handy out on the sand dunes. I bought some paddle tires once that the rim was buckled form someone before me using a skosh too much... Look close at the back wheel on the buggy. Funny thing is it still held air fine but yes it can be dangerous!
