I have a Nissan auto, and the dealer will fill my tires with nitrogen for free (I don’t use it because we have a compressor in the truck yard)

My Ford truck has regular air, I don’t think the Ford dealers offer that service. Maybe they do.

I also go to a tire store where we get our heavy duty equipment tires, and they will do nitrogen for free, if you bought tires there (saw the sign on the wall) (Kelly Tires)
