Cause it's a pia lol. I called the dealership and the guy in parts said it is ok and yes the bottom of the lugs would fit against the rim, the washer will have no contact. He said the only issue is I may hear a bit of rattling. He said that's how he runs his. I feel confident in his recommendation because he described the fitment to me and knew exactly how it is set up without me having to explain it and him just agreeing with my unprofessional opinion. I'll keep going and continue putting the winters on and like you said, see about getting some proper nuts to fit.
