I think it really depends on the conditions. But I noticed rally cars generally use Skinny tall tires so I think that would support the idea of a non deflated tire.
However if you are on really deep snow, I bet an under inflated set of tires would be more useful, to make the car float higher up and not get bogged down.
This link says to slightly over inflate.
Meanwhile
this article claims over inflating is a myth.
