Instead of ditching your good-performing summer tires, you could buy a second set of wheels and tires just for winter. For example, there's a guy in our Classifieds section selling a
mounted and balanced set of Blizzaks on nice wheels with TPMS, ready to go for a nice price. He's in Wilkes-Barre, so not far from you. That whole setup is probably as cheap or cheaper than a set of Conti DWS tires, and then you get to mount your sticky tires back on the car in the spring.
