Very surprised about the rubbing. Your running an aggressive offset, but other are running even more aggressive with no rubbing. I wonder if it has anything to do with the KW's. Is it rubbing on the fender or the suspenpension??
My new wheels are 20x11.5 and running a 325 on the rear with no rubbing.
