Unfortunately my camaro came new with nitrogen filled tires that the dealer installed. I had to pay for that, not like I could have them reclaim it and refill with normal air. I was tired and just wanted to get my baby home. They already took the pinstripe off for me at no charge. Heck, the air we breath is 78% nitrogen anyway.
You are right, as long as the air does not have allot of water in it.
