I have tried alot of these methods of dismounting a tire and in the end what I have found works the best I know own its a Bead Breaker made By K&L Supply, costs several hundred dollars but makes me glad I bought it evertime I use it. I own one of the harbor freight ones, it sucks, you will be in a bad mental condition after using it. Alot of the cheap bead breakers are made for car tires and the like which to not have the rib on the rim to keep the tire on under low pressures like at atv has. Using ether is exciting, people die doing it. I have done it and do it but I have a bead cheetah that is much more effective. I know if I didnt have the equipment I do I would be paying someone else to do it.
