Yep, 255/35-19 is listed at 26” OD, which is pushing it for clearance. I tried my 265/35 rears up front, and they definitely would not work. Some folks just let it rub, being aware of it at sharper turning angles. IMO, there is no acceptable solution with 19” wheels. The best option is 18, using 275/35 tires (25.7” OD).
