I didn't say they all had the same properties. I did say they (oxygen,
nitrogen and argon...which make up 99% of air) do comply with the
ideal gas laws.
As are as oxidation...
inert and oxygen is reactive. However, the oxidation inside the tire
is ponderously slow. If it weren't, all that would be left inside a
tire after a few weeks would be the inert gases argon and nitrogen,
which is what you wanted in the first place.
As far as nitrogen not conducting heat...horse pucky. Even if it were
true, what difference would it make? Tire heating is caused by
rolling resistance, friction and flexing of the rubber. The heat from
the tire is transferred by conduction to the gas on the inside (air,
nitrogen or whatever you have filled them with) and distributes
thoughout the tire primarily by convection. The only thing the gas
could conduct the heat to is the wheel, but the wheel is directly
connected to the tire so heat is transferred to it by conduction,
which is quite a bit more effective than convection.
