Exactly how I feel! Wayne, December 1st, I'm going out late to Firebird.

Land speed record tires and heavy commercial and military aircraft tires are operated at very high pressure (roughly 300 PSI). In the event of a crash and fire, the release of high pressure air would make the fire worse. Since nitrogen doesn't support combustion (at ordinary temperatures), it is a slight safety improvement to run pure nitrogen in high pressure tires.
The one real advantage to running pure nitrogen is that the purification process removes the water vapor that's present in ordinary air. Water's liquefaction point is in the ordinary temperature range, so tires containing moisture won't exactly follow the ideal gas law. But we can achieve the same effect with ordinary air by using a desiccant filter (used for spray painting) on the output of our home compressors.

Just my two cents worth.........Nitrogen changes volume depending on temp so little is why most ppl use it in their tires. In highspeed applications it is critical that the tire stays the same diameter with the same pressure if possible and I believe it becomes non-linear at a certain point, so the tire could easily burst or at least come off the rims. A lot of the real high speed cars run either solid wheels with no tires or solid rubber tires super balanced.
At legal highway speeds our tires only gain a pound or two if they are inflated correctly and have no problems. They will only loss a couple of pounds if the temp gets real cold. It is interesting that tires gain heat more quickly if they are grossly under or over inflated.
I guess it is each to their own, but around here I have seen it advertised for upto $7 per tire for the nitrogen fill. I bought a small "E" cylinder of nitrogen last year for $32, which would fill about 100 tires at 32 PSI.
Maybe I should open my own business...............

That article is 100% on the money. Everything else is cow pie material.
Pressure sensors have been around many years in caddies. Those old farts aren't dumb enough to fall for the nitrogen fad, and their sensors have been just fine.
I've got a nit wit friend that manages a tire store that pushes that crap. What does he here many times a week. My tires leak and your salesman told me nitrogen doesn't leak.
It's tire store snake oil. Period. Yes, maybe if your name is Craig Breedlove or Jeff Gordon you may have a use for it. But Joe Bloe in his street car - Air, Air is what you need.
Repeat after me:
I will stop falling for these marketing scams
I will stop falling for these marketing scams
I will stop falling for these marketing scams

No way man, Nitrogen gave me an extra 50HP, I swear it really did... 
Woops, that was helium, yep helium in the tires reduces the weight of the car, best mod ever!!!

Why would I want to put something in the tires of my C6 that very few, if any, service stations carry? Where I trade, they have plenty of air and it's free.

with air in your tires the pressure changes 1-2 psi when warmer, is it worth paying 60$ or more for nitrogen that will not do this??? i dont understand why that would matter much but that is about the only true statement about nitrogen inflation...it not leaking out as fast dosent really matter because its not like you can drive on it for an extra 50 miles at regular speed like a run flat or something. But if you want the constant tire pressure i guess this is for you everything else is bull
