Wheel Sizing
 

So it's been awhile since I've been on here and my xB has undergone quite a few changes over the years...but I am looking at possibly a staggered wheel fitment of a 17x8 30 offset on the front and a 17x9 30 offset rear. Right now I have 17x7.5 35 offset front and rear and they fit fine. The question I have is regarding the rear with 9 inch wide wheels. Does anyone know if it will fit without rubbing? I also am lowered 2 inches on springs.

I can't answer your exact question because you don't list the tire size you're thinking of using. That said, I always use the tool on this web site to check out that kind of question:
