Well not exactly. It's about moisture. PV =3D nRT is the IDEAL gas law. Moisture effects the pressure. That's why race cars use nitrogen in their tires. Also driving at 200mph for 500 miles makes the tires really hot, so reducing the combustibility inside the tire is helpful. There is some effect of moisture on pressure sensor life in the tire but you really don't need it in a normal commuter car.

"Moisture", what's that? Oh! I remember, that's the stuff you get when you don't live in the deserts of AZ or CA ;-)
They peddle it around here as "less leakage", which is a crock... air is already 78% Nitrogen to begin with. And Nitrogen-filled tires won't change pressure with temperature any less than with dry air. ...Jim Thompson

I love to cook with wine. Sometimes I even put it in the food.
