Just got Michelin X-Ice X-i3's with Rial Como 18's from Tire Rack. Got the 225/50/18's to replace my summer 255/35/20's. Awesome tire with super grip in snow and not bad performance on dry pavement. Low to no noise. Wheels look awesome, and total price was $1,500 delivered, vs. 3 grand for Audi wheels at dealer. The Rial's are very high quality (made in Poland) and look OEM on my 2012 A6 3.0T Prestige. Highly recommended.
