My 2019 Giulia Q4 has the stock 17" wheels with the Pirelli P7 Run Flats (yuch). I want to upgrade the tire, but at this time because I live in the NYC area, do not want to go 18 or 19. Terrible road conditions. Considering the Continental DWS 06 Plus, but wonder if I can upgrade size to 245/45x17 or 235/45x17, using the stock wheels, for a performance gain. Any potential for rubbing?
