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.

Not at all. However, UV is supposedly a player in rubber deterioration.

There is not much you can do about O3, you'll just have to live with it.
