275 30 19 Nitto NT-05 tires on 19 x 9.5 et 26 looks great on my lowered RS6 with PSS9's. Fronts rub badly on cornering, finally got to take a sporty jaunt with a willing passenger in the right seat. I'll be getting the fenders rolled to clear. I am somewhat disappointed I have to do this but the car really needs the wide rubber and looks great on the HRE's!
