there is considerable debate about this, it is used in race car tires because the pressure is more constant from cold to hot. In theory you get better gas mileage because of this. I use it in my drag car and after a burnout the pressure doesn't rise like air when hot. The reason for this is that nitrogen has no moisture in it, the moisture content in compressed air expands and contracts at a big rate in relation to heat or the lack of.
Nitrogen mixed with normal air
F1 teams use Nitrogen to fill the tires because of its low dilatation compared to air, a small dilatation in a F1 tire will result in unbalancing the car.

It is nitrogen.
most used is nitrogen..
Nitrogen and oxygen = Air

Street cars air (which is manily Oxygen, nitrogen), race cars nitrogen.
Nitrogen can be used to inflate airplane tires, off-road truck tires, military vehicle tires, and race car tires for improved performance, more tire mileage and better fuel economy.hope it helped :)
Nitrogen, because it is an inert gas.
