There was slight rubbing on the very bottom of the front Ford mud flaps when turning. Dealer trimmed them only slightly and that's all it took. Very well done, not noticeable unless you know. Good question on the off set, I should know that lol. The toyos are wide at 12.5" and stick out ohhh maybe 3/4" by eye. Couldn't be happier with this setup, just has a nice natural stance and handles like a dream.
