According to the ideal gas law there is no difference between Bone Dry Air and Nitrogen in how the pressure responds to changes in temperature. The real difference is that air contains trace amounts of water which condenses at cooler temperatures and could have some marginal impact on pressures. This is more of any issue with airplane tires where water will freeze in the tires at altitude.
As for me, I'll continue to run my custom 79% N2 / 21% O2 mixture.
