In the world of radio controlled cars they use acetone to unglue tyres from wheel rims, they recommend taking the parts you want to unglue and placing them in a sealed Tupperware container with a small amount of acetone in an eggcup (for example) the fumes are supposed to permeate through the adhesive and desolve it, although it takes around 24hrs, try googling 'removing rc tyres from wheel rims using acetone',
