I'm starting my pre-winter tire search, and am curious about other people's experience with carbide studded tires (pros, cons, durability on dry roads, effectiveness compared to regular winter tires, etc) for a climate where I may experience snowy streets an average of perhaps 1 day per week through the winter, with perpetual snow banks and wetness in between the snowstorms (i.e, frequent ice in low spots, etc).

I'm inclined to go with the Schwalbe Marathon Winter tires so I can run on the non-studded center tread at higher pressure on dry days, and let the studs do their thing with lower pressure on the snowy days.

Any thoughts?
