Is using Nitrogen a bunch of hot air

Remembering high school physics: P1T1 = P2T2. In other words, you heat a gas up a certain amount then the pressure goes up a certain amount. Doesn't matter what gas you're talking about. Maybe they mean no Oxygen is safer and better (uh, less oxidation). Ya, I'll buy that.

Anyways, I just bought a Coupe w/Sport pkg today (yahoo!), and it has green caps on the valve stems. Does that mean they put Nitrogen in the tires, or are they just pretty green caps?

Well your physics is off a bit but you're right about it not nattering what gas it is. An stability is quite a vague statement. Although I have no experience with nitrogen in tires, it does seem like a bunch of hype..

Ya, it was late last night. I believe the equation is P1/T1 = P2/T2. Corrections welcome!

those equations assume the same gas on both sides of the equations....

Think PV=nRT...

n2 is ever so slightly more stable. No reason to pay extra for it. Costco does n2 for free though!
