Tire pressure when traveling
I have the Tire pressure monitoring system < my tires are load range E and inflated to 80 PSI which is what is called for on the tires, when I am traveling they heat up to where the tire pressure is ...

You can use nitrogen in your tires if it makes you feel better as it is more stable than oxygen and will not raise the PSI as much as it heats.

Under equal pressures, all gases expand at the same rate. A gas expands by the same proportion as the temperature rises, provided external pressure remains the same.
True however nitrogen is a "dry" gas unlike oxygen which contains moisture, and as a result will not see as dramatic changes in PSI with temperature. This is one of the biggest reasons racers use nitrogen for consistent PSI across varying temps.

exactly why Nitrogen is used in race car tires (nascar). I live in the desert and even in summer they are always @ 80psi cold.
