Another way of breaking beads...well actually two ways. Take one of the old metal car ramps, set it on the tire close to the rim, then just drive your car up the ramp. The other way that works well is jack up the front of a car or truck with disk brakes, take the tire off, slide the tire you want to break the bead on under the rotor and lower the vehicle slowly. I've used the second one alot and haven't had an issue rotors afterwards.
