MTB type tread, slow and steady. I've traveled over streets that are practically glaciers. The way to do this if you have unplowed or heavily iced over stretches is to stay out of higher traffic areas if possible and don't made quick changes in direction, avoiding quick stops...use your feet as needed.
This has taken me though 40 winters....I am going on 51.
PS Even the oval knobs on some Chinese made 26" 'cruiser' style tires will work for this. I won't run with a flat tread pattern, regardless of how it's siped.
