I live in Denver and with the changing conditions on a day to day basis that we experience here I knew I needed a good set of all season tires. I should mention that I don't like the cost and the pain of having a winter/summer set of tires.
So with much research and after reading all the reviews on the Continental DWS all season tire I knew they would be an excellent set of boots to strap to my RWD 2006 BMW 325i. Through the dry, rain and heavy snow they have not disappointed as of the first 1000 miles. (meaning I can't comment on tread life quite yet)
Prior to the Conti DWS I had a set of michelins and bridgestones on the front and back. While I can comment on my prior set of tires performance in the snow, I'd rather not. What I can say is the road noise and driving comfort were much improved with the DWS! Overall they offer supreme comfort and balance for city driving and elevated highway speeds.
As for the reason why everyone buys this tire: While not a full winter tire the DWS has yet to fail me and land me flat footed through 6-8 inches of snow we recently experienced. The car feels balanced and well planted with minimal oversteer and steering lock if I plant my foot down while entering a corner. But when the TC and DSC kick in my tires regain traction and the car regains its balance on corner exit and I'm off again to attack more snowy apex's! Which is something I can't say with the rear bridgestone tires that nearly landed me into the curb if it weren't for my cat-like car control reflexes earned during my karting days.
What I can say and what many reviewers fail to mention (as commented on above) is that even though the 325i is a RWD with the DWS tire and the addition of traction control and stability control the tires fare very well in snowy/icy conditions. I've been impressed with their grip under heavy acceleration as well as under heavy ABS activated braking. Road noise as mentioned is minimal for an all-season tire but I've also been impressed wit
