Tire Inflation: Nitrogen vs Air

It makes no sense to put in nitrogen unless you can somehow bleed out all the air in the tire after it's been mounted. Regardless if you pull out the schrader valve and put a full vacuum on it you will collapse the tire and break it off the bead before it would be completely void of outside air. People need to pull their head out. The part that causes pressure variance is temp induced on the moisture in the air. Fully filter and dry the air before putting it in and the pressure won't change just like nitrogen. Chances of someone buying good quality air driers just to fill car tires is non existent. Better chance of going and using a scuba tank that has filtered and dried air. Next thing you'll hear about people using helium to lighten their car. Buying a small tank and opening it inside the car with the windows closed to make the car lighter. It rates up there next the electric supercharger for your motor.
