I just found out after doing my first set of tires that useing acetone (sp) is the best way to break down the glue. It sat in a bucket 24 hours and poped right off the rims and saved the foam!. I tried one tire doing the "boiling" and it worked but it made the rim hard to handle without bending it. I didnt even try the baking method because I didnt want to stink up my house. Gotta love youtube how to videos!
