The real reason for the more predictable pressure change is that the nitrogen is processed to remove almost all water vapour. The water vapour is what causes much of the pressure change during extreme heat cycles like race conditions. The difference is negligible in normal street driving.

Now I did have a friend that had a big 20# can of Freon 12 and he used it all summer to fill his old tires. Well Freon 12 has a boiling point of 75 deg F +/- and the first cold norther that came thru left all his tires flat.
