Anyone use this winter tire? From what I can tell, it is a relatively new offering from Cooper. Consumer Reports tested it, and the nearly IDENTICAL Mastercraft Glacier Grip II (made by Cooper), and they said good things about the Mastercraft (and were not as kind to the Cooper, even though it is THE SAME TIRE, other than a SLIGHTLY different tread). Since Coopers are more available for me than Mastercraft (local stores), I was thinking of trying a set. Anyone have any opinions?
