I saw this in an advertisment for a tire shop that said they would fill the tires with Nitrogen. My brother that just came from California and said this is big over there. Has anyone heard of this? tried it? is any of this true?

A well inflated tire can help you get better gas mileage, but now what you use to inflate the tire can also help with mileage.

The tires at Consumer Tire are some of the first in the area to get filled with nitrogen, not compressed air.

When the tires go back on the heavier nitrogen won't leak as much and that will keep tire pressure constant.

"The tires also run cooler because nitrogen tends to maintain a cooler temperature and tires that run cooler, they last longer and they get better gas mileage," said D.D. Coley of Consumer Tire.

To get that extra one or two miles a gallon it's a one-time cost of $10 to inflate all four tires.

The system, which takes nitrogen from the air and stores it, costs $8,000. That's making other tire dealers take a wait and see approach.

But NASA, commercial airlines, and auto racing haven't waited to use the nitrogen approach.

"They said Nascar does it too and that kinda sold me, y'know, $10 to do that," said Frank Nichols.

For the average driver, the savings could be a few cents, but for anyone who drives for a living, big savings can add up quickly.

"Right now we spend an average of $27,000 a year in fuel so anything to get extra mileage out of it, especially with gas prices, was a no-brainer," said Matt Starke of NAPA Auto Parts.

A no-brainer for everyone to save money if consumer tires mileage increase numbers are right.

"You're easily going to recoup that cost probably in a month, depending on how much you drive," said Coley.

In addition to Consumer Tire in Mentor, Terry's Tire Town in Stark County is also offering the nitrogen fill-ups.

The biggest plus, in my opinion, is that nitrogen, being inert, is kinder to the tires.
It is also dryer, being "processed..

Hmm, interesting. but $8,000 for them to get it? go to any welding shop that uses nitrogen as an inert gas and use the regulator on the tank set to whatever psi you want and fab up a connection so that it can fill a tire and you are set.

Unless they are using some kind of 'special' nitrogen.

Also unlike with regular methods if you use a regulator to set the pressure all tires will be exactly the same PSI Vs. putting some in and checking the pressure than purring more in etc... which also helps with economy.

But for $10 you can't really lose.

I can't wait to laugh at tuner cars with "Nitrogen Filled Tires" decals.

looked around and found:

So if your tires were inflated to their proper inflation
pressure at installation, say 100 psi, then they will
be 100 psi at 30 degrees and 100 psi at 115 degrees.
The added bonus with Nitrogen is there is no moisture
in your tires."

Look for a nitrogen filling station in your area. Nitrogen
can extend tire life by 25 percent, improve fuel economy,
eliminate rim corrosion, and tires will run cooler.
Also come to think of it the big $8000 machine is prob needed to purge the tire of air so that only the nitrogen remains or it would just mix and not work that well.

I just can't see this making any difference as long as you maintain your tires well, just the temprature that day would probbably have more of an effect than this.

It makes sense for NASCAR and NASA where the tire can get VERY hot or be moving very fast and for NASCAR they have extreme tollerences when it comes to the tires, my car does not :)

In doing some research some people are comparing Air, to Oxygen which is pretty funny when they start talking about molecule sizes and that oxygen is more dangerous in the tires (/duh oxygen is different from "Air")

Seeing as how "Air" is about 78% nitrogen, 21% oxygen, and 1% other, making it %100 Nitrogen doesn't seem that radical does it? it is already the primary... ingredient if you will.

only reason to do it IMO is to not have to check the tires as often and get some spiffy green valve stems :jester:

We have that here @ Costco (where I work) We were the first one to get this in Canada. I have this in my R/T and also my neon.......Haven't really done the math as for MPG but one of the good things about this is that when you have a leak, it takes longer for your tire to run flat (30-40% longer) so this is almost like having a "run-flat" tire.

Which Costo in Montreal? How much did it cost? How long did it take to do?

:confused: Nitrogen inert ...?!? :confused:
Neon and argon are inert gases, not nitrogen. How many "simple" nitrogen compounds can you name off ...?

I do, however, think you're onto something with the nitrogen being dried and therefore not as prone to heat effects as "normal" compressed air. Seems like using a home compressor with a drier/filter in-line would be just as good. Now if I can just figure a way to break-down the tire easily so I can get more of the "bad air" out before re-assembly ... :)

I've been hearing a lot of positive things about nitrogen filled tires and not one single bad thing. I am strongly considering trying it out when it comes time for new tires this summer...

Just keep in mind it's not the nitrogen - it's the lack of moisture in the gas (whether it's N2 or "air") ...

Nitrogen is not technically an inert gas "noble gas" however it does not react with itself or most substances.

Neon, Helium, Argon, Krypton, Xenon, Radon, are the true inert gasses.

I wonder what effect Helium would have :) most of those other gasses are not as 'dry' as Nitrogen and some are susceptible to temp' changes.

Under pressure it wouldn't be much lighter then any other gas. Did you ever pick up a full and empty helium tank?

I would like to see any real test that get 1-2 MPG more with any gas. As long as you check your pressures you should get the same MPG with free air. A nail in your tire will go flat just as fast. Sounds like a plan to sell **** to a horse farmer. Then again people buy bottled water.

The one in Pointe-Claire (the West-Island) and it cost around 8,000 to 10,000$$ Canadian. They installed it in a couple of hours. We got that around last June. Oh and they don't charge for it, as alot of people would think. :tongue:

Cool, if you see a guy pushing carts with a red coat and glasses, come say hi ok? That would be me ;)

Isn't Nitrogen highly flamable. I could be very wrong though, I hated chemistry.

D76G12, you're certainly right. Forgot the def. of inert...
Cperez44, no, not flammable... The butane/propane in Fix-A-Flat that is often found in trunks sure is! Tell your tire guy if you ever use any-- he could get hurt breaking down your tire! If he smokes, makes a spark, etc...
LFL, I knew there was some reason DOD uses it in Aircraft tires,besides the moisture issue...

No, nitrogen is definitely not flamable. It makes up 78.1% of the earth's atmosphere, so we'd be in big trouble if it was. :eek:

I thought for sure this was a joke until I saw all the replies. I was waiting to see the "yeah, and it adds 25 HP!" comments... :D

To Clarify what Nascar uses, According to all the folks at Goodyear the only allowed substance in its tires is compressed air. Of course compressed air contains over 70% nitrogen.

I bet they use a drier/filter on the compressor! Or if they're not allowed to do that then they could always import compressed air from Phoenix or Tuscon ... :biggrin:
