Just figured I would throw my two cents in here. I have a set on the factory lariat wheels that are 285's and after driving 800 miles on the new tires, I have noticed most of the squirm is gone. They still have a little, but that is to be expected with a high depth low contact block tire. I am running 80/80, yes 80 front and rear and think it rides fine, so you might try to up the pressure a bit. Watch the wear pattern though. Oh, and nice pickup; looks like mine except the gold lower rockers.
