I put some new treads on my friends 2006 f350 yesterday. They are nitto terra grapplers 295/70/18 or 35/11.5/18 and they fit with no rub and no leveling kit. This is kind of a newer size to come out so id figure i would give ya some pics. He is going to level it anyway for looks but i was curious to see how they fit without doing the leveling kit. At full crank and even through dips, no rubbing at all. Here are some pics.
