Changes in Air Temp and Tire PSI
If airing up tires to 80 PSI (Manufacturer recommended Max cold pressure indicated on tire) while air temp is 45 degrees and then traveling to a warm climate, will I likely have to let some air out? W...

Pure nitrogen has ZERO advantage in car/truck/trailer tires.
Negligible yes, Zero, not quite. Nitrogen molecules are larger than Oxygen (even though atomic weight is less) so pressure drop over time due to the fact that tires aren't completely "air tight". Now to start with even with "regular" air your already at 80% nitrogen.
And since the process of getting pure nitrogen eliminates any water vapor there is less pressure variation due to changes in water vapor content.
The later can be solved by using an dry air source.
However, IMHO in the end unless it is free, offers no advantage worth paying for in consumer applications.
