Certainly wouldn't (or couldn't) dispute any of the science in this
interesting topic but I believe the advantage of Nitrogen over air in a race
tire comes from it being well dried and consistent as opposed to the vapor
laden air from our garage compressors.

The volume within a tire is not constant. Otherwise one would not
have
centerline wear in an over-inflated tire.
I can attest that Nitrogen does result in less changes in tire
pressure during racing. If the tire pressure change is lower as others and I
have observed, it reflects less heat transfer from the tire body to the
Nitrogen inside. I graduated from ChemE so long ago and used it so little
that I can not explain the exact science.
