Is anyone running nitrogen in their tires? Net info states no moisture to corrode wheels and tire air pressure sensors, tire pressure not affected by ambient air for a constant tire psi, slightly better mileage.
Pros/ Cons? |

| Let's not forget all that extra horsepower. |

I'm still not buying into this yet. Does it really help?
Maybe someone can try to apply the same concept by filling their trunk with Helium filled Balloons and see if there are any significant MPG improvement. That's just me. |

I think the better mpg is supposed to come from the psi being stable and correct all the time.
I can't imagine this working, and I surely can't imagine it recouping the cost of the inflation... anyone know what the cost is? |

I've been the nitrogen-filled route with an Infiniti M45, and I came away a non-believer. Why?
First, the tire isn't filled completely with nitrogen. To do that, they'd have to pump out all the air in a vacuum, then fill it in a sealed box surrounded only by nitrogen. That just doesn't happen. They simply let out as much air as will escape when they remove the valve stems, then refill with nitrogen.
That means it's only maybe 2/3 or at most 3/4 filled with "pure" nitrogen. and the rest is plain air. So it's "contaminated" from the get-go.
The result is that you will see the same pressure fluctuations you will with air (which is about 85% nitrogen anyway). With my Infiniti, I saw as much as a 4psi difference from morning startup to a couple hours of highway driving. My tire pressure also dropped enough once to set off my TPMS on an unexpectedly cold morning.
The other point - about wheel corrosion - is not an issue for most people, since it takes aluminum alloys many, many years to break down from oxidation. And, after all, isn't the outside of the wheel still going to be exposed to the air?
The main benefit to nitrogen is that it is drier than outside air, but again, if it isn't 100% pure nitrogen, you still have moisture in the tire.
Now, in NASCAR and F-1 race cars and airplane tires, it may be beneficial, but those tires are generally filled under more exacting conditions.
The long and short is that nitrogen is useless the way it is done by car dealers and most tire stores. Just stick with air.

It's free at Costco. |

ANY gas is effected by ambient temperature. Do not let anyone try to tell you that it is not. Some are effected more than others.

| Nitrogen Inflation is overrated, stick with air. It has lasted this long, why switch now? |

A lot of the "benefits" about Nitrogen are just hype. I agree. However, there is one real benefit. Your tire will loose tire pressure slower then with regular air. It's true air is mostly nitrogen, but it's got about 15% oxygen in it too (among other stuff). The oxygen molecules are super small compared to the nitrogen and will leak out through all the imperfections in your tire/wheel seals more easily. Bottom line; the less oxygen in the tire the longer it will hold it's pressure.
I agree, it's ridiculous to pay for this minor benefit, but, if you can get it for free (like mentioned above), then, go for it :29: |
