Maybe
FWIW
I watched the psi in my Magnum with the 4 wheel real time monitoring to see how much the pressure swings relative to temperature. Granted the 20" wheel with wider tires is a larger air chamber, but it still proves the point.
The temp swing here in 2 weeks was from 9 degrees to 62 degrees per my dash temp, which has proven to be pretty accurate. The psi swing was from 27-41 psi The heat from driving normally raisies the psi 2 lbs in a 10 minute commute, so use 39 as the top number. That is still a 12 lb swing.
On a lopro tire 27 didn't show an extra bulge and 40 didn't add any harsh feel on a heavy, long wheelbase car. I don't run pure Nitrogen, just the typical mix we all breathe. BUT those numbers do show that in a scenario where inflation is crucial and you aren't **** about checking the psi it could save your **** to run Nitrogen.
Protecting the TPMS is a nice bonus I hadn't considered. Beating the dead horse here brought us another nugget, and a few actual facts to consider
