Got Nitrogen?

[CoeCEO]

So I filled my tires with Nitrogen too.

See this thread:

Pretty cool really. I happened to be at a meeting at the factory that makes the units which filter Nitrogen out of the air to fill tires. The unit deflates the tire to 2 PSI, refills then deflates back to half PSI and reinflates a final time. This guarantees something around 95-98% Nitrogen in your tires.

See the link in that thread from Carbeaux

I believe I have nitrogen in my tires. When I first got the truck I had trouble with the tire sensor, and they said that this would help. That and there is a N by one of the valves on one of the tires.

What are the advantages of filling your tires with Nitrogen?

[CoeCEO]

Well.......

Nitrogen gas does not expand and contract due to heat as regular air does. So this is very useful in avoiding the pressure warnings in areas with cold winter seasons or extremely warm temperatures.

Also due to the molecular properties of Nitrogen, it does not escape from your tires like oxygen and other gasses found in air.

It is also an inert gas which prevents rim corrosion.

No. All ideal gasses expand and contract at the same rate. PV=nRT

Leakage IS a function of molecular weight. The smaller the molecule, the faster the leakage. Nitrogen is 28, air is collectively 29, so it actually LEAKS FASTER than air.

Your last reason is probably the only one. With no oxygen, there is no oxidation. So the inside of your wheels will stay shinier.

Nitrogen is a scam that tire places use to get an extra $5 per tire from us. The "regular air" they put in, which is what we breath, is already 79% nitrogen. I'll call BS all day long that the extra 20% nitrogen makes a difference with ride or anything like that. The only thing I agree with is the oxidation factor, but I can honestly say that oxidation of the inside of my wheels is not even remotely a concern of mine.

But 'air' is not an ideal gas- using pure (98% pure?) makes the pressure predictable. Useful in racing or other hi-performance apps- IMO useless for a street vehicle.

In a high performance application like road racing in a humid environment it can be a benefit but for a DD it wont do much.

Costco does it for no extra charge, but I would never pay for it over air.

My tires are a mix of regular air, co2 and nitrogen since I refill them with various tanks.

I'm not sure where you are getting your information, but it's not accurate. Yes, air is an ideal gas at tire pressures and temperatures. And the pressure is predicted to be the same with 80% nitrogen (air) or 98% nitrogen or 100% nitrogen.

[RangerNewbie]

So you're saying that the composition of 'air' is the same from every source?
Same amounts of water vapor, particulates, trace gases etc.?

[debos titan]

this is pretty good stuff..

[latenate]

I have to go review the perodic table, be right back....

No, I'm saying that air behaves as an ideal gas, ie., PV=nRT applies. The pressure response to temperature change is predictable, and the same for all gases, including water vapor, argon, etc. Particles are essentially incompressible, and not subject to changes in volume with temperature.

Wasn't this already hashed and re-hashed and then hashed some more in the last thread regarding Nitro??? I think I'm having de-javu

[blueskys]

One can never have too much hash.

Why do they put gaseous nitrogen in aircraft tires?
