Well, I'm not sure if they make them in the right size but my dad has been getting toyo open country AT's for the company trucks and the guys are loving them. He plans on putting them on his truck once his BFG's wear out, said they're a good bit less than the TA/KO's and seem to get better traction.

 

I'd see if you could find a Michelin tire to fit those...cause i've never gone wrong with Michelin!
