In my opinion, it would be better to hand up the extra cash and get like new ones... I know what you mean about the used "rustic" look, but face it, a deals a deal, and you want tires this expencive to last as long as possible. If the extra money is not easily come by, then offer a better offer on the more used tires.... Also if you are not EXTREMELY hard when wheeling, I don't see where 33's would hurt your dana 44 at all... aside from wearing down faster on the road...
