So, I'm wondering; if air is only 21% O and 78% N, then how much improvement would there be with pure nitrogen? And would it be cost effective. Most places I go, air is free, but nitrogen would not be, and if you weren't close to a nitrogen filling station, what would you do - dilute the nitrogen, then have to start over again? Cost effective - or a money grab by tire shops?

I have a modest RV, and I carry an air compressor because the tires take 65 psi, and if I develop a slow leak, I'm not stranded.

I’m wondering the same thing myself. I have read that there is some anti-rust benefit when using Nitrogen as Oxygen and air moisture can expedite rim rusting. However I’ve driven a number of cars over 250K miles and I never had a rim rust out yet.

The biggest plus is that air is free. Or used to be as gas stations up here charge 50 cents, USD, to start the compressor We also have our own compressor so air is still free for me
