On my rear wheel, I have been running a Continental studless winter tire, and really love it. It is a soft-rubber tire with lots of siping, so it is pretty grippy on white ice and hard-pack snow -- much better than a slick or commuter tire that one would run in the summer time, but not much different in rolling resistance. Great combo. Two years ago when we didn't have a huge amount of snowfall, I ran pretty much the whole winter with this setup and loved it.
