Daryl, I would like to see the science behind that one.

Maybe a definitive test at the track sometime when doing practice runs.
Run one tire with air, one with nitrogen. Begin the run with pressures
the same, the same tire make, model etc, same age, same wear (preferably
new to eliminate vagaries), Measure temp and pressure at start, and
again after a defined number of laps. That should do it. Nobody can ask
questions then. You have the hard data to back up the premise. Nothing
like hard data to back up your position.

Yep, that would be a good one.
