Alot of places won't touch that. So, find a hole in the wall place that don't ask questions. And tell them it's strictly for off-road use only. If you tell them that it will see hwy use, they might touch it. I personally would get it vulcanized, and then mount them up on some bead locks, and run the piss out of them. Or if you can find a used one to match the other three, and use that one as a spare.
