Taking advantage of a $100 off [via a prepaid Visa card] sale, I'm having the Conti DWS installed. With the discount, $628.62 installed for 4, not bad, from my research. Folks here seem to like the DWS, and the rears on mine (245/40ZR-17 Michelins, on it when I bought it in October) are due, though the fronts have some wear left. As best I can tell, not having the receipt, the Michelins were about 3.5 years old, with between 20-25k on them. I hope for longer life from the DWS ..... I'll report my impressions later.
