Nitrogen in tires, where to fill up?

I have personally tested the differences in pressure fluctuation and it is actually quite drastic.
Pure nitrogen also leaks much slower than air. Saying that air is 78% nitrogen is a bogus argument. It's 22% other components. It's those components that are the problem. That's like saying water is part Oxygen, so go ahead and breathe it.
