In my experience, one studded tire is all you need. If you're going through a lot of snow and need some extra traction for the back, then spring for the knobby cx tire (i.e. Maxxis Mudwrestler). If you don't think you'll need a ton of traction, then the Panaracers will be just fine (and will also be useful when the snow and ice is gone).
