I just ordered the Dunlop Wintersport 3Ds on 16 steelies from TireRack. Ran my Conti all-seasons last year, and they could barely get me out of a puddle. We do not get a lot of snow here [though they are saying this year could be a bad one], but I drive a few hours north quite often so need something that will deal better with left over slush and crap, as well as the occasional non-plowed driveway and lazily plowed NYC streets.
Seems like these are the perfect balance between snow handling [vs. studless] and performance. Also looking forward to the 16" diameter with less tire to push through the snow. Seems like cheap driving insurance o me, and there is no way i am running the Dunlop Z1's in any kind of snow. Scary
