We deal with mostly ice around here, with the occasional snowstorm. Marathon Winters are great, because there is typically bare pavement and icy stretches. I haven't heard any studs on other commuter bikes yet, but we're getting close. Studded tires are mounted on an extra wheelset, and a couple missing studs from last year were replaced. Really haven't had a good winter storm in a couple years, so we are due, perhaps.
