Ice tires for winter commuting on non-icy roads?
I think the tires would be durable enough (my winter commute in nearby Kitchener, ON is about 20 km/day and my Marathon winters hold up pretty well) but they're definitely going to feel more sluggish than a road tire.

If you're normally running them with enough air pressure to keep the studs clear of the pavement, I think that kind of defeats the purpose of them (and that much pressure makes the ride a little harsh for my liking as well). Carbide studs will last as long as the carcass of the tire holds together, and there's always a chance of running into an icy patch somewhere, even if 99.5% of your route is bare and dry.
