Ugh.

I tried 4 different studded tires last year, though the last set I got in April at a 2 for 1 sale. They never saw any snow or ice on their break-in rides.

Last winter was horrible around here for biking. A combination of freezing rain, thaws, snow, and slow plowing meant the residential streets were often covered in rutted ice topped with a layer of trafficked snow.

Tried A10s but they were inadequate for the conditions. Marathon Winters were much better on the ice but weren't very good on snow. Nokian W106s didn't roll as nice as the Winters or the A10s but were a bit better on the bad stuff, - though I wished they had more studs.

I finished the year by getting a set of Nokian W240s. Those things are not so fun on pavement, but I'm hoping they'll handle the ice and and at least some snow pretty well.

Wear isn't much of a problem with quality carbide studs.

In your climate it sounds like the Marathon Winters may be a good choice. They're really a nice tire and I tried to like them but they just couldn't handle much snow.
