That was very interesting; thanks for sharing. I was interested to learn about the FAA(?)'s requirement for a "non-combustable atmosphere" in the tire.
Have a good one,

As much as we try, this still won't be the end of this argument. We've thought it was over and put to rest more than once here. There are guys here that swear they get "a better ride". 
At least this is a good find and the next time it comes up, all we have to do is post the link. Or maybe it should be in one of the stickies.

I could be wrong but from what I've seen, the big teams all have large nitrogen tanks for multiple purposes. I think it's more of a convenience. It's cheap and they use it for air tools as well as tires. No compressors to plug in and maintain as well as portability.
Then on the other hand, would it be totally out of the question for the "pro's" to have fallen for the hype too?

The air tools are huge plus at the track.
My paintball gun runs on C02 and will freeze up if, I'm laying down too much fire.
My friend (if he is on my team) or the target, runs on N2. He can fire his 16 paintballs a second, until he runs out of ammo.
Plus is there a cost difference? I don't think so, but could be wrong

One of the better links:

I'm NOT advocating the benefit of a Nitrogen fill, but their the argument against it doesn't make sense.
Since I don't have Nitrogen fill in my tires I can't tell how the "liquid" nitrogen slushing in the tires sounds like.
Can anyone enlighten me?The only and real benefit of the Nitrogen fill is because it contains less moisture.

What do they use in F-1?
I believe Ferrari uses CO2. It was part of the Spygate scandal.

According to Racecar Engineering magazine (Dec 2007), Ferrari was using 50% CO2 and 50% HFC 404A.
This mixture apparently keeps temps down and pressure constant. Speculation is that this is why they were able to run on the softer tires longer.
It's a cool article.

Look I know we have charts on our aircraft for the difference in temperatures for our tires and gear struts.
I have plenty of tires filled with nitrogen that go low.
We also check tire pressure daily on our aircraft

Can you post the article? Otherwise, I will have to head down to Barnes & Noble and read it there!

We use nitro in our tires on our Modified cars as well as our West Coast Pro Truck. It is convient to have in the pits to power the tools and add air to the tires. There were slight advantages to Nitro when it came to tire pressures etc... This is from my experience. We get it for free from our fuel sponsor. I never thought of filling the Vette tires with it. To be honest I probably never will.

That site may look scientific, but lacks some basic knowledge. They dispute Nitrogen filled tires being "dryer" because Nitrogen is "liquid" under pressure. Are they real?

I think he meant that it is in liquid form when he buys it in the tank. It's under much greater pressures in there. I don't know what it is but I'll guess over 3000 psi. It is NOT liquid in your tires.

I doubt a high dollar team would do it for nothing after all in NASCAR they talk about 1/2 lb. air pressure adjustments which I find hard to believe makes a difference. What do they use in F-1? I know LGM uses for tires and I have seen many others filling at AMLS race. Do I buy into all the hype, no! I bought a smaller tank to take with me but worry about DOT regulations I was going to get a big rental bottle for the house for the intial filling. It is cheap.
with that 1/2 psi voodoo.
