I put helium in mine, softer ride and better gas mileage. In this photo they were overfilled a bit lol <br/>

If just "air" What is the point of my Dec 1 delivered 2016 having a NitroFil flyer and NitroFil valve caps.
I am not saying this stuff does anything but it seems the factory- not my dealer - sent the car out the door this way.

"Available at leading automobile dealers and service centers everywhere."
Definitely dealer installed, not at the factory.

The only thing that can make a difference in terms of pressure rise is IF the nitrogen is truly dry (no H2O) and the plain "air" is humid. As the tire heats up, the water in the humid air can vaporize, increasing pressure more than a dry gas will.
Will it hold pressure better? Marginally. Nitrogen molecules are bigger than Oxygen molecules, so the O2 will diffuse through the rubber slightly faster than do the nitrogen molecules. But as others have pointed out, regular "air" is 78% nitrogen anyway, and even if the nitrogen your dealer adds to your tires is pure, they don't evacuate the tire of all the plain "air" first, so you still have a mix of nitrogen and "air" in the tire.
Even if you could get the tire filled with pure nitrogen they will eventually lose pressure, and the pressure will still vary with temperature so you still need to check, and top off, your tires.
The minor advantages of nitrogen simply aren't worth paying for.

Pulling a high vacuum on a car tire would almost certainly damage the internal tire structure. Definitely a big no-no.
