We all should know... Hard tires means hard rubber = no sticky on the road.
Also, deflating the tires help expands its surface area... for better grip.
Adding the two together; they work VERY well on snow... You'd be surprised how much of a difference just the tires can make alone.

But it's all about how much pressure is on the contact patch per square inch. More pressure means the tire can bite into the snow and ice harder. Why do you think rally cars run narrow, knobby tires with high pressures on snow? It's because less contact patch means that more weight and pressure is put on the tread. But if you wanna try telling the rally drivers that they need wider tires with lower pressures for their snow rallies, good luck. My advice is to experiment with this first hand. I'm sure you will find that higher pressures give more grip and control on hardpack snow vs lower pressures which can cause it to glide across the surface more easily.
This reminds me of that episode of Top Gear where Richard Hammond goes to the salt flats in Utah and tries to meet a target speed and some guy who had been going there for many years told him he needed the lowest possible pressures for his tires. Well it turned out that was the reason he was so slow and when he tried the opposite and increased his tire pressures, he met his target speed. But you must admit, tires are a difficult beast to understand.
