A larger contact patch (lower pressure) is better for ice grip.

A smaller contact patch (higher pressure) is better in snow in most conditions. Usually you want the tire to dig down to a grippier surface underneath.

In some situations it's better to try to stay on top of the snow with a larger contact patch though (more like a snowmobile). This is the case when the snow is too deep or maybe if there is a layer of ice underneath.

I would just run similar pressures to summer. If you get caught in some bad freezing rain you could think about maybe dropping the pressure by a few psi. If you're using winter tires in warm weather, higher pressure might be better to keep their temperature down for reduced wear.

I typically run 36psi front, 30 psi rear.
