Put a set of Specialized SWorks tubeless tires on HED Ardennes Plus wheels, Orange Seal sealant.

One ride, 40 miles.

Trying to remove them to put different tires on. Front tire no problem. Popped the beads and could take it off easily. Rear tire seems glued to the rim. Finally soaked the wheel in hot water (figured sealant water water solvable, so couldn’t hurt) and could get one side off. Still can’t get the other bead off. Soaked for an hour without the bead budging

Any suggestions?
