When my car was new the tires were filled with nitrogen from factory or wherever. Tire pressure was consistent for two years or more. After that I figured tires were old enough to start loosing air. That’s when I had to occasionally top them off, but, never let them get low enough for tire light to come on.

I never put nitrogen back in them figured it was waste of money and good up charge by dealer. My understanding nitrogen molecules are larger and temperature changes don’t affect nitrogen as much as plain moisten old air. Even when my car was new I still checked tire pressure once month. Waiting for tire light to come on iMO asking for tire wear, but that’s me I am asinine on certain stuff.
