A trick I learned once..
Remove the wheel and lay it flat on the ground on some wood, remove the valve stem, place a 4ft long 2x6 like a ramp from the ground to the edge of the rim. Using a spotter person to tell you when to stop, use your car and drive slowly up the 2x6 and let the weight of the vehicle pop the tire off the bead. Back down, get your spotter to rotate the rim and repeat, then flip it and do the same on the other side.
Then muscle the tire off the rim with soapy water..
Maybe not for people to want to change tires all the time, but for occasional Joe it works and is cheaper than a bead breaker..
