How long can a tubular tire remain glued on a rim before it should be removed and remounted?
Seems to me the adhesive used for tubular tires has a finite useful life, no matter the brand or type. Is that true? I'm not referring to shelf life before being used to mount a tire, rather working life after mounting. If so then logic would suggest a tubular tire should not be trusted after a period of time since it was mounted.

Deflate the tire and check the glue strength by pushing the tire away from the rim. If it holds you are good to go. If the glue is dried out and pulls away from the rim time to re-glue. I would re do them every two years regardless.

Fully inflate the tire and really try to pull off the tire with your hands by applying as much force as possible to the side wall. If you can roll the tire even a little bit it might be a good idea to reglue especially if you use the wheels for heavy cornering or descending. That being said I have a set of competition wheels that I haven't reglued in five years and seem fine.
In theory with your tire inflated to tubular pressure (120~150psi) there should be enough pressure from the inside of the tire against the rim to hold the tire in place even with weak glue. And pulling the tire on and off repeatedly can ruin the tire, so you might wind up also replacing your $80 tire too...
