Okay, I should have said "dry nitrogen", but I assumed (incorrectly) that it was understood that what I was referring to was dry nitrogen. The pressure of dry nitrogen WILL NOT CHANGE with a change in temperature as long as it is not compressed to the point of becoming a liquid. So, the nitrogen you`re talking about it not dry nitrogen, but dry nitrogen is sold in HVACR parts houses and welding supply places.

for whatever that's worth.

In the oilfield diving business we deal with gasses all day long. Size of the molecules has a lot to do with how well a gas stays put, among other things. You couldn't put helium in a tire, for instance. Well, you could but it wouldn't stay there because the He molecules would pass through the rubber in short order and escape to the atmosphere (flat tire).
Nitrogen has no super duper properties. It follows the rules of the ideal gas laws just like any other gas. Charles Law is one of those gas laws. Pressures are directly proportional to absolute temperatures, same as we learned in school. Bottled gasses are dry because thats the way they're bottled by the gas handling companies. Nobody is interested in paying for contaminated (water vapor) gas so they don't produce it,, bad for business.
Air from the atmosphere via a standard LP shop compressor contains moisture. Nitrogen, Oxygen and Helium, which you get from a bottle courtesy of a gas plant is free of all but trace contaminants. Water, as stated, is a contaminant.
Apparently when you introduce a gas into a rubber tire there is some sort of voodoo effect that takes place whereby a gas no longer follows the rules of physics. There is apparently a voodoo periodic table too, that contains more than one kind of Nitrogen. I can't speak to this as I'm unfamiliar with the practice.
