I check my tire pressures every 2 weeks or before a long trip and guess what, have yet to add air to my tires this winter.
I'm surprised this thread has gone this far. I would expect a gimmick like this would be easily seen for what it is by a group of such generally conservative people.
I doubt your tires didn't need air added going from high 90 to -20. The pressure would have dropped 10-12 psi easy, and N2 has no effect on that anyway. Bead corrosion accelerated by salt/water/oxygen is a major problem in the Midwest. I have seen bead corrosion on a majority of the wheels I have mounted tires on. Even newer cars less than 3 years old. It doesn't help when most wheels anymore are not manufactured to prevent it. The wheels that seldom show corrosion seem to be the German cars. Most of the rest are terrible at resisting corrosion, and wet oxygen doesn't help at all. Moisture, just like oxygen will try to equalize. In the humid summer it will permeate into the tire, and in the dry winter, it tries to get back out.
