That makes sense. If I kept cars longer I probably would do it to a few of them.Nitrogen lasts longer in the tires as it has larger molecules and can't get out of the same cracks. It is resistant to water formation, so there won't be any water in the wheel. Nitrogen is really nice for tires, they last longer because they don't rot from the inside.
If you are getting new tires, spring for the nitro. and then make sure you use a nitro fill station if you ever need to add air.
If you were in a situation on the side of the road, one could still use the old air pump to get you to town though, right?
