Les, You need to go and study those chemistry books yourself. All gasses
do not have the same properties! They all have different boiling points,
freezing points, coefficients of conductivity, chemical properties, etc.
The fact is that nitrogen is pretty inert and does not interact with the
rubber in the tires and contribute to dry rot. No oxygen implies no
oxidation! Nitrogen filled tires do not conduct the heat caused by rolling
friction and flexing. They remain at pretty much ambient temperature and
therefore the pressure within the tires stays pretty constant - Your Boyle's
Law reference!

If you believe that, then you have never taken a class in chemistry.
That stability story is one of the nonfacts that nitrogen tire fill
equipment makers use to push their pretty much worthless machines.
Nitrogen, oxygen and all the other gases that make up air expand and
contract at exactly the same rate with temperature. Pick up a
chemistry text and read the chapters on "gas laws."
The only added value to filling tires with nitrogen is for the person
selling the service.
