I've read of people running tubes with beadlock rims either because their tires are rotten or because their beadlocks won't hold air well. Perhaps give it a try and if it works you could sell them in good conscience explaining it to the buyer to recoup some of your money or maybe you'll dig the 44's. If the structure is still intact, I bet you could run them bald. Probably depends how rotted they are, but what's to loose. I know I'd like to see them on there.
Sorry about your situation.
