Another reason to use nitrogen is to reduce the amount of moisture in the tire. Moisture will lower the boiling point.

All gasses obey the gas law, PV=RT. The only benefit is that the Nitrogen will be free of water, which will turn to gas if the air in your tires reaches 100 deg C. That's not gonna happen, except on the racetrack, maybe.
But the
gasses in the atmosphere all stay gaseous at any temperature you will ever encounter, and so will all see the same pressure increase.
Nitrogen in tires is BS.
