Believe me I understand all of the above.

The tires are 265/75/17 Bridgestone Dueller II on a 4x4 Tahoe. The tires are rotated every 15k miles. The truck is used for towing. They were put on when the truck had 33k miles. It now has 73k miles. I had an alignment after the were put on, none since. It is driven by myself and my wife, 50/50. I am an aggressive driver, she is not.

Anything else you are needing to try and debunk my testimonial?

Hi- Sorry, distracted by Las Vegas Girl. Can't think, know nothing about Nitrogen... But Las Vegas I do.

Come visit our local forum- gzcon.org

Back on topic, getting my thoughts back- With the heat here in the Vegas, you would think it would be nice, but the inconvience far outweighs the benefits. I can't think of anyone who uses it, including the track junkies. I use good old fashion $0.25 Air.

Oh, I have access to Nitrogen and still don't use it.

So you admit that there are benfits, but minimal

the ideal gas law is called the "ideal" gas law for a reason. the ideal gas law assumes that the gas particles have no point volume and have no attractive forces. since nitrogen particles are bigger and intermolecular forces are stronger, they resist speeding up (due to heat) and therefore maintain pressure better. results of course are not going to be drastic, but it does help, especially when driving on the track where tires heat up.

gains are not great but they are there.

Notice I said "and devations from it". Air is already ~80% nitrogen! Nitrogen has an atomic radius of ~75pm, while oxygen has an atomic radius of ~73pm. Size difference? Negligable. BTW, by your logic, water vapor would actually help with limiting pressure fluctuations because of its high intermolecular forces

The concept behind this idea is the fact that nitrogen is a bigger molecule than oxygen. therefore it is less permeable. hence, it stays in your tires longer. Thus, your tires retains proper pressure longer.

yes... you don't have a control.
whats to say its just ur driving. put 40k on the same tires with just air, and if there is a difference, then your testimonial might be creditable.

im of the same mind set as redlude97
technically, there might be a minimal difference. but no one here will be able to tell/test/detect it because it is soo small. in the real world there comes a point where places after the decimal point become pointless, even when you are working with theory there still exists a point of who gives a ****.

(has your wife ever stopped at a gas station to top off the air in the tires?
do you feel it would have made a difference if she did?, or, if she did, would the differences be .. Negligible? )

Its a testimonial

Obviously it is based on my personal experience with using nitrogen, and my previous experience with this and other vehicles using air.

I think that's a pretty measurable source, and also what I was testifying to earlier.

Has my wife ever topped of the tires? HAHA your funny

So how about we merge this thread with all the other nitrogen in tire threads?

the NHTSA says in their study that it doesn't make a difference because O2 will permeate back into the tire to reach equilibrium in real world tests.

you have to fill the tire with a 50/50 mix of o2 and n2 to see those types of results.

Considering air is 21% oxygen and 78% Nitrogen... your mixture is super heavy on the O2 side.

It's been debated many times over and over.

Just so you know, some car dealers are now recommending Nitro for tires to save on gas mileage.............they have pamphlets in the dealership to explain about it.

I have also heard that nitrogen keeps the tire from losing maleability/becoming brittle. Whether thats true or not who knows.

Oxygen is corrosive and damages the rubber.


Pure air is ~75-78% nitrogen, the other 25-22% is trace gases, which are corrosive in nature. Nitrogen is inert, so it doesn't react with the rubber. Also there are smaller gases which tend to leak out easily, so by eliminating those small trace gases, you can maintain pressure in a tire easier.

However, the outside of the tire is still in contact with normal air, so you will still get gradual rubber breakdown..but the tires should be worn out well before you get to that point.

Does nitrogen work? Yes. But I wouldn't go out of my way or pay extra to get it. I do fill my tires with it because I have access to 99.9% pure nitrogen at my work. Hell i could fill my tires with helium if i wanted and make it lighter!
