i've ran em all. the nitto is a good quiet tire, but the a/t is not worth a crap in mud. u gotta spin em too hard to keep em cleanin. great highway and winter tire though. the m/t is a great tire, but didn't get very many miles on em. the good year mt's are good in all conditions, but also too soft. i didn't get enough miles out of em. the best all round i've found is the toyo m/t's. i've got a f-350 with 110 gallon slip tank in the back. i don't pull a trailer a lot, but travel at higher speeds than most. i run 55 psi in the front and 50 psi in the back. u'll get great response in all conditions with the toyo m/t and good milage if U ROTATE THEM REGULARILY!! i do mine every oil change. got 55k miles on the last set. if u don't rotate they'll get loud too. definately the best bang for your buck imo.
