My wife actually called me from the coast on one of her trips, she had a low pressure warning trip on her Honda. Stopped at a service station and had some mook tell her she couldn't use their air to top off the tires, because "nitrogen was required". I got mad by proxy, and asked her "as a multiple Master's holding science teacher, what percent of our atmosphere is N2?" She teacher talked that idiot and went on her way with proper PSI.
And they can sell more tires and alignments.
But in reality, even if they service my wife's Grand Cherokee and over-inflate the tires like they always do, once winter hits here, I deal with the TPMS warning saying a tire is too low.
I had mine aired up for towing and forgot to air them back down. Winter hit and I got TMPS messages! You'd have to air some of these up pretty high to avoid that message.
Not a total fix - from AAA -
Since nitrogen does not completely eliminate temperature-related pressure changes under normal driving conditions, it is of little benefit to vehicle owners who properly maintain their tires.
Tire sites will tell you to use nitrogen because they charge for it and you keep coming back to them instead of filling yourself. But since air is 78% nitrogen anyway, the difference is minimal.
