I never really understtod why people used the boil, or bake method. After doing it alot thwe wheel tends to warp a little and it takes some effort. Just buy some regular ol' Acetone, and submerege you wheels in there for a day or so. The tires peel rigght off the wheels, and theres no glue residue or anything left behing. I just like to spray the wheel with alchohal (or even water) just to make sure all ther acetones out, and then put some more tires on.
