Anyone running military tires? I am not looking to put this tire on my Super duty, but a straight axle tacoma I am building. Looking to pick them up this weekend in the 40" flavor. I know they are made for a MUCH heavier truck than my Tacoma, and have a load range of "J", or something retarded like that. They are hard as a rock and should last longer than the truck, but I want to be sure they dont ride like a set of boggers down the highway.
