My direct experience with nitrogen in auto tires is my toad. It had nitrogen in the tires from the dealer and I was always having the TPMS say a tire was low. Now the tech at the dealership could have skipped it that day but since the earth's atmosphere is 78% nitrogen I feel the added expense is not worth it. When I was an aircraft mechanic in the AF we almost always used nitrogen in the pneumatic system and tires but that was more for the "dryness" as the water vapor in compressed air can and will freeze at altitude.
