Why nitrogen?

Ordinarily, I would just let this slide; but since the greenies have decided
that CO2 (which is nature's means of recycling oxygen) and O3 (which is
nature's cleanser of the atmosphere) are "pollutants" according to the
strange reasoning of their adled brains, I feel compelled to point out that
I suggested that the aircraft would be sheltered in a hangar--which would
protect the outsides of the tires from part of the damage. They still won't
last until the treads wear out, but it will help.

You're suggesting hangars are so airtight that CO2 and O3 are somehow
sealed away from the tires inside? The effect of O3 on tires is not
through increased UV or global warming. It's direct chemical interaction
with the polymer chains in the rubber compounds.
