Garlits and Petty must be broke and need the money! lol....

OK, since "air" has a ton of nitrogen in it already, what, if any, advantage would be gained with 100% nitrogen?

I smell a scam... 

[JB400]

100% nitrogen doesn't heat up and expand like regular atmospheric air that is pumped from a regular air compressor.  It allows you to set certain tire pressures and keep them longer for more consistency.

As far as Petty and Garlits, they still have commitments to sponsors.

[Dino]

True, atmospheric air contains mostly nitrogen, but this is not about having nitrogen in your tires per say, it's about not having water in the tires which you do have when you fill up with plain air.

Do we benefit in our dailies?  Not a ton no, but it won't hurt either.  

[maxwellwedge]

Big Daddy knows a thing or two about Nitro! 

[Troy]

Certain tire stores have been filling new tires (and advertising it) for years. I think there are advantages but 99% of the population would never notice a difference (sort of like using distilled water in the radiator).

[Ghoste]

They'd both know a bit about tire pressure too.

[69_500]

I had the new tires on my Durango filled with nitrogen to see if there is any difference. Only thing I see so far after 6,000 miles is that my mpg went from 19.5 to 19.7
The first was the average over 7,500 miles, the later is since new tires. Best to date on a single tank was 23.5

I don't fell like typing all this , so I'm gonna copy and past it. "First is that nitrogen is less likely to migrate through tire rubber than is oxygen, which means that your tire pressures will remain more stable over the long term. Racers figured out pretty quickly that tires filled with nitrogen rather than air also exhibit less pressure change with temperature swings."   To me this would be a great benefit sense we get at least three cars a day wanting there air pressure checked because the light came on.

[A383Wing]

also it slows down inside tire rot from what I heard as well

[hatersaurusrex]

I call snake oil.

[Ghoste]

If it's snake oil then the nitrogen industry has bamboozled a lot of very big dollar race teams and many automotive engineers as well.
Why do you think its a bogus claim?

[Dino]

I wouldn't go that far as it's a good thing not to have oxygen in the tires but I would say it's not critical enough.  I honestly do not care if they fill my tires with nitrogen or plain air and I would never know the difference either.

I suppose it's good for the shop as they have a closed system that does not allow water to be mixed in so maintenance wise it makes some sense.

[Cooter]

Just one more uber expensive machine designed to dumb down Americans. No need ti check your tire pressure ma'am, with this Nitrogen, they will never change pressures.
Until the  flunky at Jiffy Monkey stuffs compressed air on top to 'top off' your tires.
Too damn lazy to check the tires.
You know that stupid little tire monitoring system on your new daily?
Yep...came about cause some ignorant person who shouldn't breed, didn't check the tires on their Ford exploder and rolled it.

[charger1972]

Yeah, but now we are stuck with it. And get threatened if we tamper or disable it.

Ahhh, let me clarify.  I don't think it's bogus, I think it's for racing, not daily drivers.   The wording on the cutout seems to imply that this is a dealership or some other type of consumer-based operation, and that's what I'm basing my assumption on.    For the average driver, I'd say nitrogen filled tires are just about as effective as a Tornado air intake.    I'd be willing to bet that some of the benefits listed in this thread are valid but probably small, and balanced against the fact that you'd have to take your car back to this same place every time your tire is low means that any benefit you get would be wasted in hassle and gas money, and then some.

[John_Kunkel]

Nitrogen in tires originated in the aircraft industry and it's not about expansion with heat/cold, it's about lack of oxygen to promote corrosion in alloy wheels and to feed brake/wheel fires.

Gotcha, that makes sense.  And with what John says it pretty much backs up your point.

[Cooter]

"First is that nitrogen is less likely to migrate through tire rubber than is oxygen, which means that your tire pressures will remain more stable over the long term. Racers figured out pretty quickly that tires filled with nitrogen rather than air also exhibit less pressure change with temperature swings. That means more consistent inflation pressures during a race as the tires heat up. And when you're tweaking a race car's handling with half-psi changes, that's important."


"Passenger cars can also benefit from the more stable pressures. But there's more: Humidity (water) is a Bad Thing to have inside a tire. Water, present as a vapor or even as a liquid in a tire, causes more of a pressure change with temperature swings than dry air does. It also promotes corrosion of the steel or aluminum rim. "

[ws23rt]

Like others have said. It's not that nitrogen is better for the rubber. It's the lack of oxygen that could have some long term advantage.  Argon would do just as well but cost more.

The other and more important issue is an add campaign to sell something to a public that doesn't need it. This is the snake oil.  The add company has an out in that what they say is true. Not only that but if a complaint was filed it would run on forever trying to prove a mute point.

Some folks like knowing that the coils in their amplifier are wound with silver wire. But the sound they hear remains the same. (or not our hearing goes bad )

[odcics2]

HA!  Good point!

I know guys with $300. interconnect cables in their stereo systems!

I had one come over with those and compare then to the 75 cent zip cords you get for free with cheap electronics.  After the session, he could not tell the difference...

IMO the biggest variable in a quality stereo system is the speaker.   

(p.s. a few beers make ANY stereo sound better, too!! )

If they were really smart they'd use helium to make the gar lighter!
