Best way to remove tires from rims?

[lincpimp]

My buddy has had alot of success putting the wheel/tire in the oven on bake at 250. He leaves them in there for around 20mins, then pulls the out with oven mits (safety first) and pops the rim out. He says the ca just breaks down and gets like really thick grease. After the ca cools he says it will flake off the rim pretty easy.

He did say that venom tc wheels sagged a bit at 250, but proline plastic wheels did fine...

He said that most of the ca stays with the wheel, and not much is left on the tire.
