Need help finding a tire!

My truck has 33x12.5x15" General Grabber ST's on it.  This is the second truck I've had the tires on, literally, I took them off the last truck and put them on this one.  Not what you'd call an agressive tire, but good for the sandy trails I cruise on and darn good on ice and snow.  Since this is also the truck I plow with, that's important.  I don't put on alot of miles on this truck and the tires are getting pretty old, but the tread is still above the halfway point.  Here's the bad part.  One tire has a bad belt and cracks around the tread.  It looses air and isn't safe anymore.  No fun to drive on anyhow as it can only loosely be called round!  General hasn't made them in years, and the only person I can get to on their customer line barely knows what a tire is (though she was very nice).  
So I'm posting here in the wild hope that someone out there can help me find one tire, I'd buy a pair if I could.  Maybe someone has a connection at General and can get a better answer?  I'd love to shell out for a new set of tires, but I just spent the whole budget on a six day stay in the hospital.  Winter's coming soon too.  I'll listen to any ideas too, thanks folks!  Ogre.  
I'd much rather be happy than right any day.

12 seconds spent with google shows that the Grabber ST is still in production and still stocked by places like www.tirerack.com but only in 16 and 17 inch wheel sizes. However, the grabber is clearly an AT-type tire, so your options would seem to be pretty simple. If you're convinced that no other tire can possible work for you, then buy a set of 16" wheels and grabbers. Or you can consider buying any of the many other AT tires out there. I have BFG AT's on my Cherokee (the Family Truckster; the only close to stock vehicle I own) and they perform very well and are very reasonably priced.  

I'm not convinced that this is the only tires for me, actually I'd much rather have a set of those BFG's.  I've had three sets of them and I'm convinced that they are the best snowplowing tire there is.  Problem is, I'm broke and I only need one tire!  I still have my pride though and want the dumb thing to match the other three.
