What my GT1 RWD is wearing this winter, installed today. Pirelli Winter Sottozero 3 225/45x18 all around on Sport Edition P5 18X8" 38 offset in Anthracite (which look great with Panthera Metal). Rides smoother than OEM Michelin Sport 4 per the butt meter. Tire whine is noticeable but that's what the volume knob is for . Zero clearance issues with Brembo brakes. Shipped in 2 days from Tire Rack.
