Just reading that since the atmosphere is already 78% nitrogen, offering to fill our tires with nitrogen has limited/no real benefits. I never noted any difference after several tire purchases at Costco.
Nitrogen vs. Oxygen

I would venture to say most of the late model cars with nitrogen have been diluted or replaced with 02. I think the molecules of the nitrogen are larger than o2 molecules so they don't leak as quickly.

I think it's all over-hyped. Moisture in "common air" (air compressor) would be one factor. There's only so much oxygen in a "fill" of a tire, so any hype about oxygen oxidizing a tire internally would be quickly used up by the limited O2
This article here suggests that the physical size of N2 and O2 molecules is very similar

Or was that R134 molecules being a different size? I'm getting my gasses mixed up. If you think about it, a air compressor uses regular air from the atmosphere and compresses it. If compressing air reduces the nitrogen without a special designed compressor, you should have 78% nitrogen in your tires anyway.
Just another scam to get in your wallet.
Uh huh.
Yes its true the pressure holds longer with Nitrogen vs Oxygen.
If a tire store is up selling Nitrogen for big bucks go shopping for a better deal.
At Costco thats all they fill tires with at no extra charge.

Wait, can someone explain to me how the Nitrogen (N2) molecules are larger than the Oxygen (O2) molecules when Nitrogen has a smaller atomic mass displayed on the periodic table of elements? Nitrogen is 14 g/mol while Oxygen is 16 g/mol.
From what I recall, Nitrogen was used as it's lighter than Oxygen or Air (which is about 75% N2 anyways). The lighter weight means it takes less torque to spin the wheel. When the newest Generation Nissan GTR's came out they put N2 in their tires from the factory.

You'll never see the difference. No way no how.

Agreed. Put "air" in the tires, it's 75%-80% nitrogen naturally. Or pay for "pure" nitrogen? There can't be much difference.
Used on aircraft? Well that's a whole different subject.

And polish your rockers shafts with jewelry cleaner and maple syrup. It will make as much of a difference.

With the implementation of the TREAD act all 2007 and newer vehicles under 10,000 lbs now utilize tpms sensors located in the wheel. Reduction of as little as 5 psi will trigger driver warning light. nitrogen is less likely to migrate through rubber pressure is more stable. nitrogen is an inert gas and oxygen free, it is impossible for oxidation to occur. no oxygen: no oxidation, no tire rot, no interior wheel or valve rust or corrosion, no water less failures of government mandated expensive tire pressure sensors. As for the cost if a shop is forced to buy a 12,000 dollar piece of equipment with a limited service life should they not be reimbursed for the the use of the equipment???????

Read that pdf I posted earlier, it's beyond me, except that they mention physical size of the molecule is different than atomic weight.

Not old school. Just old.
There's nothing in TREAD that requires nitrogen fills for tires. Shops who spend money on that equipment do so by their own choice, and are not forced to by the legislation. They are motivated by making a profit, not by compliance.
As already stated, the atmosphere is 78% nitrogen. The idea that pure nitrogen prevents oxidation from the inside of the tire totally discounts the fact that there is oxygen in the air outside of the tire, surrounding everything. Unless, of course, you're driving in a vacuum.
And these "expensive" tire pressure monitoring sensors you speak of? Replacements are from $25 - $40 at Amazon. Breaking the bank, obviously.

I know I'm right....
Is nitrogen less reactive to rubber or steel/AL of a rim? Doesn't cost anything to top 'em off where you bought them that filled them in the first place. Headers rust/rot from the inside, tires can too.
Tire rot? I don't usually talk like this, but are you ******* serious?
That's THE absolute stupidest thing I ever heard. "My" plan with tires on a hot rod include wearing them out WAY faster than they ROT.
dumbasses unite.......and then GO AWAY.

This.... Why spend money,on the new fad? Air worked fine, for century plus. Advertised gimmicks, for the average folk..
I have to disagree.
More like advertised gimmicks for stupid folks.
Somebody had to say it.
To point out something else: The way you fill a tire, it already is filled with atmospheric pressure(~15PSI) of Air(~78% N2 as stated) before you add which ever air you prefer. You can not vacuum fill a tire unless it has bead locks, because it would unseat the bead... so unless you are mounting/filling in a vacuum or a 100% N2 environment, your "N2 filled" tires could be up to ~94% N2 instead of 78%(Normal filled)... with some O2 still in your tire. So IMO, go for it if free, can't hurt. Not worth any extra money.
