I'm pretty sure UV from the sun and constant heat cycles will kill the tire
before the air inside does.

The only thing the nitrogen does extra is keep the tire from rotting from
the inside. No oxidizing of the rubber because the nitrogen is inert and
displaces the oxygen. Other than that, it's a wash.
