Tyres can be removed within 3-5 mins by using a heat gun,just warm them up and start breaking the bead.I use gloves as it will burn you.
It will not damage anything unless you hold the heat on it for too long.
You should do one side at a time and depending on glue strength it should only take 3-5 mins per wheel.
The other method is dunking them into almost boiling water.Take them out and try removing the tyres,if it won’t come off put them back into the water.
