Why nitrogen?

In theory, perhaps. In practice, tires oxidize from the outside as well as
the inside. I've noticed that every time I've bought expensive, long-life
tires, they have to be chucked because the sidewalls are rotting, even though
the tread is still good. It's not just air, but pollutants (particularly in
the cities). Ozone, a common urban pollutant, is particularly bad for tires.
