Nitrogen filled Tubes

Does anybody use Nitrogen to fill tubes from empty? This would and does make pressure changes due to heat/cold null and void.
Assuming tube material to be non-reactive to Nitrogen. In emergencies air can be added with no adverse effects.
Seems a good idea to me as long as there's a regulator and no leakage.

I used to use a common mix with 79% Nitrogen in mine. It caused no problems with the tubes but I did notice some expansion in sunlight.

So you had some Nitrogen hanging about..........just enough to fill 79% of your tubes?
