You put Nitrogen in your tires? Must be fancy tires.
I use a special composition, about 80% nitrogen and 20% oxygen.
The FAA recommends a maximum of 5% Oxygen.

True, but that reccomendation is for the gasses outside the tire, the
ones in contact with the treads. It does not apply to the gasses
inside, which are enclosed by an FAA approved tube.
