The reason I push the DWS is I had them on my RWD G8 GT (365hp/380tq) and they were still very good in the snow, excellent in the wet and phenomenal in the dry. I'd probably get them once the Yokos are no more.
Ok. So the Conti Pure Contact / ecoplus are new. No reviews. http://www.tirerack.com/tires/survey....jsp?type=GTAS
Looking at the prior Conti tires in the Grand Touring All Season segment, they don't fare well. The question I would have is "is this tire a game changer like the DWS was?" Willing to take that chance?
The DWSs are an excellent and proven tire. It's your choice.
