Re: Tyre Pressure/Temperature - Tire Volumes Change

       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.
