Cool! I'm on the fence about spending $130-ish for some Schwalbe Marathon Winter tires.

Question for you, or anyone who cares to reply. This could go in any of the winter tire threads, I suppose, but I chose this one.

Recently while riding into a parking lot at what I'd call "medium speed", on street tires on a rigid 26" vintage mountain bike, I was leaned over and pedaling though a corner that I regularly ride. It was dark, and though I was running two very bright headlights, I didn't see the sheet of ice on the north side of the building, which blocks the low sun this time of year, until it was too late.

While leaned over, the bike just came out from under me and down I went. The sheet of ice was actually a blessing, since while I hit hard and it hurt, I slid along the ice, which didn't tear my clothes or give me any road rash.

So, finally, here's my question: do studded tires help when banking over into a corner, or do you need to make sure you ride perpendicular to the pavement, as we do when going in a straight line, to keep the maximum amount of tread and studs on the pavement?
