so, I order a new set of 18" XXR wheels,I did not check the width, or the offset, now I am stuck with a new but useless set of wheels, when I went to get them installed, I ask to try them first, before get the tires installed, and the result is that the face of the wheel is almost 1" outside the rear panel. I almost cry, but now I know better: a 18"x8.5" w.30mm offset will NOT FIT.
