You can also do the bake method. Just heat the oven to 325, put tires on a piece of aluminum foil and bake for about 15 minutes (I usually do it for 20). Take tires out (carefully, will be hot), let cool for a few minutes and then I just press on the bead of the tire at the rim, peels right off. I can reuse the rims, tires, foams. NOTE: it will smell up the kitchen a little so I do it late at night when everybody else is asleep. If the tires are no good I will then cut most of the tire off, pull out the foams and then bake, it will be less smelly. I have been doing this for years.
