Riding on ice, or any slippery surface, one should turn while keeping the bike straight up. However studs up on the sides of the tread are important, like when riding straight over refrozen foot prints in the ice. The pressure should also be as low as you can without getting pinch flats. But, still keep the bike upright at all times. The big ruts and holes will be slightly better with studs on the outside edge of the tread. When I go over 3" foot prints, or worse, I have about 15 psi in the front and about 20 in the back. 26 x 2.35 tires.
