i got a 2008 commander....I've been looking at a set of 17x9 mickey Thompson classic locks. with -12mm offset and 4.5 backspacing. I am installing a 2" RC lift. with the new wheels, will I still have to use wheel spacers to fit 265/70r17? I want to stay away from wheel spacers if possible, so if I can't fit a 265/70, what will be the biggest tire I can fit. thanks in advance
