I now have a dedicated winter bike with the studded tires on it. It's my short-haul shopping bike, so it doesn't have to be high performance. Winter riding involves two factors in my locale: Ice and salt. I'm not sure which is worse. The winter bike lets me hang up my nicer bikes during the salt season (or to take my good old time cleaning and maintaining them). It's a single speed with coaster hub, so there's only the bare minimum of stuff that needs to be protected and cleaned.

I don't mind riding the studs when there's no ice. The studs and tires seem to last a long time. At 8 miles per day, it would take me a few years to wear them out.
