i have never tried it lol. But its been asked on the other 4 forums that i am on and everyone always recommends the oven method. So i guess the wheel doesnt melt. your supposed to leave them in the oven till it cools down. but i would keep my eye on them.

A easier way to get them off is to put them in a bowl of acetone, and you leave them over night or 2 and they just come off.
