I have been giving this some thought, and while I agree that it shouldn't really matter what gases are used (air vs N2) to inflate tires, I do think that not enough attention is paid to water.

That's right - water. If humid air is used to inflate tires, then it is possible for the evaporated water to condense out as the tire cools (especially if the tire is initially inflated during periods of warm weather, and then that same tire is used throughout winter). Such condensation will significantly affect tire pressures. That would explain why mcrews saw his tire pressures vary as significantly as they did before he used N2.
