      Air is composed of about 80% nitrogen, 19% oxygen and 1% trace gases. No need to quibble over a percent or two of gas composition.



      My understanding is the advantage of nitrogen is it's commercially dry, vs air which carries water vapor. The water vapor or humidity in the tire air is where I understand the big variation in pressure vs temp occurs.
