I have used acetone to soak a set of hot bodies tires off (pink soft compound)
they didnt feel changed at all

I have baked 3 set of tires off and it seems like baking the tires off perminantly enlarges them ever so slightly.
they were just a little bigger than the bead diameter of the wheel even when cooled completely.

I will always use acetone to take my wheels off, i know several others who have done this with no ill effects
