I haven't tried it but know people that have. If you put your tyres in an oven set at 110 Celcius (convection oven not fan forced), the glue will be the first thing that melts, but watch it carefully and don't let it over heat.

Removing glued tires From their Rims. by: sean WestCork in IRELAND
Best method is by using NAIL POLISH REMOVER and a model paint brush, peel tire back and paint the nail polish remover on to the glue,do the other side of rim re-check first rim repeat if necessary on both rims a few time until glue break's down. Stubborn glued tires use a craft knife as well.
