Nitrogen in tires

This has been discussed ad nauseum (sp?) in various forums. You will find all kinds of opinions, information and mis-information. Bottom line it is a waste of money.

Here is a definitive analysis

Been there done that.

Nitrogen 3 (2010)

Since the air that you breathe is 80% nitrogen, what do you think? Of course nitrogen will fluctuate but maybe a tiny bit less. Just the typical BS to get more of your money.
Unless it is free, nitrogen is a waste of money. Here is a link: Nitrogen or air

...since nitrogen is an inert gas you not will have the fluctuation in psi when tires warm up. How true is this statement?

That statement is NOT true. All gasses in a confined enclosure will increase pressure when the temperature increases.

What you gain by using nitrogen is that it is "dry" and does not contain the water vapor most air compressors inject into your tires with the air. The water vapor will add to the change in tire pressure as your tire temperatures change. Air, on average, is between 0.5%-1% water vapor. So without a water trap, a compressor will pump some of this water vapor into your tires along with the air.

If the nitrogen fill is free, I'd take it. If it's an extra charge, forget about it.

By the way, regular old air is 78% nitrogen already. :)

agreed waste of money.

don't use public air that may have a lot of moisture unless you have to have air.

Use a compressor that has a moisture trap so you are putting drier air into your tires.

Thanks everyone for saving me a few bucks on this scam.

+1 on waste of money. About 78% of air is nitrogen anyway. Tell him you'd like to try it for free for a while and will give him the nitrogen back if you don't like it, LOL.

Nitrogen has benefits in tires used for air craft or race cars. For a vehicle at normal speeds, it serves no practical purpose. It is a profit center for the tire seller.

If it makes you feel better, spend the money on it. It won’t hurt, but remember that it is not as easy to find 100% Nitrogen for bring tires up to pressure.

Normal air contains 78% Nitrogen, so is it worth it for an extra 22%? I think not.

The next time I tow my trailer at 200 MPH or it has the name “Boeing” on it, I will use nitrogen.

Dog Folks if you tow at 200mph don't forget to post the video!! :)

I'd rather watch that show in person.
