You make it sound like it costs 25.00 everytime you do a set. A gallon can be used over and over and over and over. You don't need an inch of tire to grab because they fall right out of the bead. I have done everyway mentioned and acetone is what I always use now. I use an old plastic cooler with and inch in the bottom. Cut all the rubber away but whats in the bead. Soak one side over night and they fall right out then do the other. Pour the acetone back in the can and use it again.
