Depending on the type of snow/ice cover on the road a higher psi and smaller footprint could give better traction due to higher ground contact pressure. Same resaon a skinnier tire works better than a wide one in snow (unless you are talking bottomless snow offroad, where those awesome polar exploration trucks use gargantuan tires for flotation.
