I have the Pirelli Scorpion Ice and Snow run flats mounted on OEM 214s, 275s up front and 315s in the rear. I had them on for since last week and all I can say is that I luv the feel, grip, and handling characteristics of these. With All the crappy roads in NYC these tires seem to just eat up the road surface. To me its as if I have the Adaptive Drive option set in sport, but of course I dont. Here are pics for reference if you need.
