Yes, very studded tires, and well tested on bare-ice. I think you've hit part of the equation for this 'perfect storm' - snow keeping the studded from getting a solid grip on the ice. And Minneapolis is VERY icy right now, we had a week-long thaw with temps just above freezing (but very little sun). So when the temps dipped to the mid-20s today, we got some nice skating rinks here, there, and everywhere... and a couple inches of fresh snow, and it's a party!
