Any recommendations for a winter tire for urban roads? I don't think snow will be much of an issue (this could be optimistic), but I am concerned about traction on wet leaves, gravel, ice patches, and all the junk that seems to accumulate in the winter on the sides of the road. After reading reviews of the Armadillos I'm not really sold on them because of their allegedly harsh ride (I ride on some rough streets and have a couple blocks of cobblestones to contend with). I have kenda kontenders now, which came stock on my fuji silhouette, and currently am getting a flat about every two weeks, which is getting tiresome. Should I be looking at cyclocross tires for traction or something slick but more flat resistant? Or something else entirely?
