What nitrogen does that is better than plain ol' air is that it doesn't degrade the tires, due to a lack of oxygen. However, as anyone with winter and summer tires hanging in the garage 6 months of the year will know, the tires them selves wear out before the insides get brittle due to atmospheric problems.
Nitrogen does NOT leak out more slowly than air. Air is 80-some percent nitrogen and therefore should behave pretty much exactly the same. Other "parts" of air have larger molecules even than nitrogen, so would "leak" even slower.

Let's all try t okeep up here, OK? Nitrogen is simply a great way to make money from people who like fads.

Actually all the dealers in my area will put N2 in your tires for free...so I guess that blows away your theory.

Oh and BTW, go here for the truth about N2....

I wouldn't pay extra to have pure nitrogen put into my car's tires though.

Sail, have you tried the nitrogen yet? Still waiting for you to prove me wrong, my friend

Will check out the link - but I'll let my theory be blown away (by nitrogen, presumably?) for now. Can't say I didn't try....

Well, that tells it like it is about nitrogen leaking, but it compares it to oxygen (only about 20% of "air") rather than to air itself.

The 4 highest constituents of air are:

Nitrogen N2 78.084%
Oxygen O2 20.947%
Argon Ar 0.934%
Carbon Dioxide CO2 0.033%

That, by my reckoning, makes 99.998% or so. I think we can ignore the rest, as they are all in the part/million area.

If only 20% is oxygen, and the nitrogen doesn't permeate out, then at the first refill with air, there should be only 4% oxygen left. When that has leaked out and been replaced, then there should only be 0.8%, and so on.
So - I am still amazed at the claims,m and will HAVE to try for myself.
As far as it not expanding with heat - THAT is BS. Pure BS. IMNSFHO

I have a hard time believing any documents that come from an organization whose mission is to "provide consumers, over-the-road truckers, fleet managers and others about the benefits of using nitrogen in tires."

The Get Nitrogen Institute claims to be a nonprofit organization, but it is clearly a marketing ploy by companies that sell nitrogen. Look at their web site and the list of "sponsors"...what do you think is their agenda? Heck, it is like the beef industry telling us the benefits of eating steak...they sure has hell aren't going to tell you about the down side to it! It is pure propaganda, and I recently took a grad school course in it so to the trained eye it is very obvious. The Get Nitrogen Institute claims that by using nitrogen would save 3,716,692,884.802 gallons of gas per year (from their web site), but they fail to inform you that the same could be achieved by convincing people to regularly checking the air pressure in their tires! That, my friends, is propaganda...the twisting of the truth to convince people of one thing; when different conclusions are also available but not addressed.

Air in tires has worked for over 100 years and whereas it may not keep its pressure as well as nitrogen, it is readily available and free for the most part (I have my own compressor, so filling up my tires is a snap!).

The bottom line is if you want to use nitrogen in your tires, that's great and God bless ya! But the benefits do not exceed those of just using air by enough to make me want to switch.
