I think they stay inflated longer and the pressure variation between high temps and low temps is smaller. I'm just a driveway mechanic/google expert though.
When your tires are filled with air... your psi might change according to the temperature outside. If its too hot... it will overinflate... if too cold... too little. This causes tire wear. With nitrogen the pressure stays the same regardless of the temp.. reducing tire wear. It's a plus in my books... but I still haven't seen a nitrogen filling station in my area.

The ideal gas law is: PV = nRT
The pressure, volume, and R are the same (theoretically). The temperature varies which is the variable we're trying to control.
That suggests that "n", the number of moles present, is less for nitrogen than it is for atmospheric air.
Air is a blend of O2 (mw = 32), CO2 (mw = 44) and N2 (mw = 28)
Gaseous nitrogen is pure N2 (mw = 28)
So yeah... I guess it takes fewer moles of nitrogen to fill up a tire than the equivalent number of moles of oxygen.

I had a feeling it was just one of those fads,I was only looking into it because Im having mad tire problems, and am having to run it 8lbs under the max so my fucking car doesnt feel like its slamming at every bump.
after I chew through theses Im going to 50 series as opposed to these 45's
