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.

Via a separate mechanism. That's why tires are made and/or treated
with ozone protection additives.

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

Bull****. Reduce the amount of hydrocarbon and nitrogen oxides
emitted by various sources and you reduce the amount of low-level
ozone produced by their interactions. I'm not talking about the
ozone layer here. I mean the air we're breathing at our level of the
atmosphere.

...and YOU are going to accomplish all of that for the good of your
tires in YOUR hangar...

WOW! I'm VERY impressed.



Yeah! Me too!


Enough to distract you from the ball of yarn you were chasing around the
floor?
