I have been just using tire spoons and a big hammer to break beads... That's awfully hard on your back, and I'm getting too old for that BS... I watched a fellow use one of these at a tractor trailer shop in Kansas years ago and it looked like the way to go except that they are a bit pricey... I used this to break the bead on a Subaru rim to replace the donut with a real tire... It worked pretty good and it only took a few minutes working around the rim to break it without bending over... I like that, and another good thing about it is it should work on most rims... It was worth it for me... Tough tool, works well, and I don't think I'll ever be able to wear it out...
