Nitrogen in tires? Anyone know anything about it?

I was flipping through the channels, insomnia in full force, and caught the tail end of some news bit stating that there were some service stations that were filling up customers tires with nitrogen.

Anyone hear of this before? or had experience with it? The news fella said that it added 3-4mpg???? Sounds rediculous.

I googled it and found that it helps preserve the tire, and helps keep it at a more stable pressure, closer to spec. I guess that could help in gas mileage, but I dunno.

Re: Nitrogen in tires? Anyone know anything about it?

I know in most autosports, teams use nitrogen in their tires because it gives a more stable pressure, and is not affected by outside influences at much. I.E. Humidity in the air.

It provides a more constant and predictable tire pressure, and this helps the teams make pressure adjustments precisely, without having to worry about it being inconsistent.

As far as better mileage, I have no idea. A wide factor of things goes into determining your mileage.

Its mainly used in racing b/c as a tire heats up and then gets cold and back and forth through its cycles the nitrogen will not produce any moisture and also keep the tire pressure more accurate and consistent.

About the mpg??? Probly not but I might be wrong.

It's good because if the T1000 tries to kill your mom, and blows out one of your tires in a volley of fire from his MP5K, he will freeze and be unable to move... which will allow you to fire the last round from your 1911 to shatter his ***.

We used nitrogen in the 70's and 80's when we were racing.

I beleive just about everyone else was using it also.

We still use it in our 355/360 challenge cars as well as the 333sp's

Re: Nitrogen in tires? Anyone know anything about it?

Having your tires inflated to the proper pressure does improve gas mileage relative to having them underinflated or overinflated. The amount of improvement is going to vary depending on about a hundred other factors. 3-4mpg is a best-case estimate, probably compared to driving on tires with no air in them at all.

Atmospheric air is like 78% nitrogen anyway. No big deal here.

Re: Nitrogen in tires? Anyone know anything about it?

when I worked for advance auto, we started filling our delivery trucks up w/nitrogen, overall saved the company a bunch of money per this newsletter thing for employees...

longer tire life and slight better over mpg, worth it in the long run for a company trying to make money/save money on every possible front

i use helium because it makes the tires lighter. that increases fuel mileage and acceleration

Costco uses nitrogen.

I could see getting 3MPG from nitrogen if you filled one car's tires with nitrogen and one with regular air on a 100 degree day in the middle of the summer and then come a zero degree day in the middle of the winter you'd never bothered to adjust the pressure... the air filled one would be way low on air pressure, and air pressure can easily make a 3mpg difference.

But realistically it just keeps you from having to worry as much about temperature changes affecting your tire pressure.

They use it in jet plane tires because it is not affected as much by temperature as regular air.
