I think this has a lot to do with the many variations on tire styles. For example, my previous set of tires that were 265/70R17's and they fit without rubbing on stock wheels with 1.5" spacers but they were an all terrain tire. Now, my current tire which is a mud terrain would not even turn without bending the weld and molding the liners because the shoulders of the tires are much MUCH wider. As I said, that is with stock wheels and the spacers. When it comes to having different wheels and offsets I trust your opinion since I know you know your stuff.265/70R17 = 31.7-31.9 inches tall depending on the tire.
I have yet to see a forum member running either 265/70R17's or 255/75R17's and not have to bend over the pinch weld and either trim or re mold the inner plastic fender well.
