I replaced the OEM Continental Touring Contact AS tires on February 26, 2013 with the Continental Extreme Contact DWS 215/45ZR17 tires. The handling and ride quality is 1000% better than the OEM tires. The ride is comfortable yet firm. Tirerack did a great job mounting and balancing the tires, as the tires were part of a tire & wheel package - I ordered them on Sunday February 24 and received them on Tuesday February 26, as usual great Tirerack service. I have not had them in rain or snow yet and will post a follow up survey after they have been in rain and snow.
