I put Continental Extreme Contact DWS (275/45/19) on my 09. I started out in Florida where I bought the Treg and drove through extremely hot days and some huge downpours (read: gothic rain / lighting storms) at freeway speeds with absolutely no issues. Then, a nearly 4,000 mile road trip from FL to Portland OR with more rain and very bad roadway surfaces. DWS still performing very well. Then, moved to Montana where, for the first time with these tires, I just tonight drove through 3.5 inches of fresh snow and packed ice streets. The DWS handling was acceptable in fresh powder at slow surface street speeds. The Treg stopped when I wanted it to stop and it turned where I wanted to go. But I have been driving very gingerly -- afraid to do anything likely to cause me to lose traction. I did hit some extremely slick packed snow / ice and I began to slide. However, I was still able to make a 90 degree left turn without braking. The highest speed I have driven in the snow so far was 31 MPH. As I continue to drive the DWS this winter and in various driving conditions, I will update this post.
I can say that th DWS is an excellent highway tire and performs well on long interstate runs in all types of weather. And now, they seems (so far) to be performing at acceptable levels in snow. Ice however is a complete different animal and I'm not going to rely on these tires to perform anywhere near the levels of Nokian WR's which I had on my Audi A6 and allowed me to do freeway speeds on hard packed snow and ice. Check back in a couple of weeks for my DWS winter/snow update.
