Is using Nitrogen a bunch of hot air

Zdom

I went to the local tire dealer with my dad to get new tires on his car and they were promoting having your tires filled with nitrogen vs. compressed air. Any truth to their claim?

Nitrogen is more stable than just putting air in your tires(In regards to different climate conditions). The GT-R showcases this from factory with Nitrogen filled tires.

The only real advantage is that it leaks slightly less slowly. But because it leaks more slowly that leads you to be lazy in checking your tire pressure. Pressure change in response to ambient temperature is roughly the same. Interior oxidation is a non-issue, exterior UV is far more harmful than O2.

Just check your pressures once a month or more and you'll be fine. Wish they had left the tire pressure display screen, even a $20K Chevy has that now.

^^^ Check that link.

Btw composition of the earth's atmosphere:

Nitrogen (N2) 780,840 ppmv (78.084%)
Oxygen (O2) 209,460 ppmv (20.946%)
Argon (Ar) 9,340 ppmv (0.9340%)
Carbon dioxide (CO2) 387 ppmv (0.0387%)
Neon (Ne) 18.18 ppmv (0.001818%)
Helium (He) 5.24 ppmv (0.000524%)
Methane (CH4) 1.79 ppmv (0.000179%)
Krypton (Kr) 1.14 ppmv (0.000114%)
Hydrogen (H2) 0.55 ppmv (0.000055%)
Nitrous oxide (N2O) 0.3 ppmv (0.00003%)
Xenon (Xe) 0.09 ppmv (9 × 10−6%)
Ozone (O3) 0.0 to 0.07 ppmv (0% to 7 × 10−6%)
Nitrogen dioxide (NO2) 0.02 ppmv (2 × 10−6%)
Iodine (I) 0.01 ppmv (1 × 10−6%)
Carbon monoxide (CO) 0.1 ppmv (0.00001%)
Ammonia (NH3) trace

nitrogen is more stable under different temps... i dont use it though.

ChrisSlicks

Stable how? As in less likely to burst into flames?

Scam scam scam.. Whats awesome is the "Discount Tire" and tire chain stores charge you for it..

oh and hahaha.. that .pdf you attached is painful to read..

"Nitrogen dissipates heat, reducing rolling resistance and therefore enhancing fuel economy."

What a crock..

Well, any time you have your tires properly inflated you will have reduced rolling resistance, I guess that is the point. But how it magically makes heat disappear (something the laws of physics says is impossible) I have no idea.

I use it. We have a Nitrogen machine at the dealership I work at. I thought it to be bull before I started using it. My Audi TT I had was the first car I tried it on and the first thing I noticed was the ride was slightly improved (Low profile tires). Then my TPMS warning stopped coming on due to ambient temp changes!!(happened monthly before) General pressures did not fluctuate as much. We charge $39.95 one time then free refills!
Now my wife's and my Z have it. Not going back!!
If you think it's to much money to have the service you shouldn't be in this hobby!
I think we are priced higher then those tire chains also!
Also: For those who call it a scam...why does Nascar and F1 use it?? I guess those engineers are inferior to your wisdom!

At the price of having tires put on, it should be no charge if you wanted the nitrogen!

I only do 78% nitorogen

kevr6

I think we are set at 95% or so!!

I agree! We do that with tire purchases!!

No, no, no, none of these reasons are why nitrogen is used. The real reason, although hidden from the public, is much more reasonable than these stupid performance claims. Nitrogen is used because of the new TPM systems used in new cars. These units are made of metal. Regular air contains a slight amount of water vapor, and more is created with the heating of the tire. This water eventually corrodes the sensor units and contributes to their failing, ala the reason so many cars all of a sudden develop TPMS problems. Nitrogen doesnt contain any water vapor and therefore cannot corrode the sensors over time. It is used as a convenient cover up for manufacturers botched TPMS sensor quality. New units are being made of plastic, so nitrogen may see its way into extinction. You won't find this info anywhere or hear it from any dealer, only technician magazines, etc. Just an FYI, so spread the word, more people need to know of this scam and demand better manufacturer quality, not costly cover ups.
