acetone is the best method IMO for removing the tires from the wheels. put something in a container for the tires to sit on, the vapors do the work, so you only need acetone in the bottom of the container and make sure you put a lid on the container you use. will save the tires, wheels and foams, so you can reuse whatever you like. My brother just did this with a set of slicks he had mounted on slash wheels, dismounted them and remounted them on a set of hazard wheels for his SC10 4x4
