I fill mine with 78% nitrogen

Wait, isn't dry air like 78% nitrogen??? Haha (that's not a real question I know the answer is, yes)

Nitrogen fill is pointless

Mine came with the nitrogen...on my G35 to...not sure there are any benefits to it. Yes? No?

The benefit to N2 fill is that Nitrogen is more "dimensional stable" than just straight air. As a result of this temperature changes affect the tire pressure less.

Methinks Does Nitrogen Tire Inflation Improve Mileage & Savings? puts it best:

Nitrogen tire inflation appears to be little more than a clever marketing tool with a tiny bit of scientific benefit supporting it that is blown massively out of proportion.

When it comes to street driven cars. But it doesnt expand to the heat from the tires like normal air does. Hence why it really only applies to track purpose cars. Helps with maintaining a set tire pressure even as the tires get hot.

Found this a the F1 sight. I did not check the math.

"For road cars.... when the tyre is put on the wheel it is full of air at 1 bar. If it is pressurised to 2.5 bar, then you are adding extra 1.5 times the tyre volume, hence the tyre contains 60% dry nitrogen and 40% wet air. Air at 20C with 75% humidity contains 13g water per m3, the dew point is 15C. This means water droplets will start to form in your tyre at 15C."

The only reason to use N2, it's why we use it in aircraft.
