Mazda service centers have their own Nitrogen generators and Im wondering what Tesla think about Nitrogen.
I inquired about Nitrogen at Jax tires and they said $8 a wheel. Involves hoisting the car and vacuuming each tire before filling with dried Nitrogen. The article above states that whatever you fill your tires with, its important that it has no moisture content...

Nitrogen is worth the expense if, and only if, 1) your area has constant fluctuations between very cold and very warm weather or 2) you regularly drive on very twisty roads and/or drive aggressively.
I do not currently use nitrogen in my Tesla, but neither of those conditions apply.
I have used nitrogen in every aircraft I ever owned (>50 all told) and in several cars (Ferrari, Maserati, Porsche).
The cost is not really worth it otherwise, in my view. If the cost is minimal I would certainly do it now.
Another advantage in tyre longevity is that the lower expansion rate of nitrogen coupled with the dry interior (all reputable nitrogen fillers dry the tyres prior to loading with nitrogen), but that advantage is very small without one of teh two situations above.
The other small advantage is that the larger nitrogen molecules leak less rapidly than do those of the oxygen in air. That is also a very minor point, unless one of those two conditions apply.
In my view it is really nice and good for a tyre dealer or car dealer to have nitrogen, but tesla does not do that. In my ~48,000 km, I have had to top off only two or three times, but i measure the pressures about once per month anyway, out of lifelong habit.
FWIW, the cars I had that I filled with nitrogen were easy because i had nitrogen in my own shop for the airplanes, so it was easy. Would I have done it otherwise? Probably, but I do not know for certain.
BTW, if you have 21" wheels on an S, 22" on an X I would use nitrogen because those tyres are subject to greater stresses and have less tolerance for bumps than do the others, they also wear much, much faster.
