There are actually THREE "what can/should I use to inflate my tires" answers:
Nitrogen
DRY air (with air dryer to remove moisture from air)
WET air (you know-- those coin op machines with water dripping from the air chuck)
Nitrogen and dry air both follow the Ideal Gas Law (PV=nRT). For a given temperature change, there WILL BE a given change in PSI.
Wet air is NOT an ideal gas and will give more PSI change for a given temperature change.
yup, excellent summary.
And a common and easy way to remove moisture uses a permiable barrier will remove the moisture and remove most of the oxygen giving you dry nitrogen.
hence likely the nitrogen fill. But filling with dry air is for all practical purposes for most applications just fine.
