Anyone fill their tires with nitrogen?

Tire place was trying to sell me on this today... Hadn't heard of it before, but it sparked my interest...

 
nitrogen isn't flammable, at Earthly pressures anyway.

the advantage is it expands and contracts less with variations in temperature, than plain old air. I think.

 
Unless it cost an incredibly cheap amount, I can't see it being worth the amount of money you're paying for it.

No, it is not really flammable. Much much less so than oxygen anyways. Nitrogen is used to pack explosives in order to make them more stable for transportation. Anyways, compressed air would be mostly nitrogen anyways, nitrogen is the majority component of our atmosphere. It has a slightly higher specific heat capacity, so, uh.. having more of it might be better if your tires get really hot 😕.

my costco does it for free.

Well, see, there it would be worth it 😛

But since OP was talking about his tire place trying to sell it to him, that sounds like they'd be charging him money.
 
I have heard about it, but I really cannot guess why a fairly inert gas would be required in tires... also, since air is 78% nitrogen I would assume most of the reasons they provede are BS...
 
i wonder what happens when someone gets their tires filled with nitrogen then they go to the local gas station and put in some oxygen.....anything bad coming from this chem geeks???

IINAC (I am not a chemist), but I imagine the nitrogen would just be diluted with compressed air (which is not 100% oxygen, only about 20%, I think), and over multiple refills and leaks, the composition of the gas in the tires would approach the composition of the air. Nitrogen gas is not very unstable, and I don't think it would react badly to atmosphere.
 
I have mine filled with Nitrogen, but I have $500/ea tires on my car as well...

If you had just regular all-seasons, I wouldnt worry about it... for high end sports tires, I'd go for Nitrogen.


-- Zerocool84, Since air is made up of mostly nitrogen anyway, mixing the two will do nothing bad... you'll just lose the effects of having pure nitrogen in the tire. if you run low or get a leak and you are unable to fill with nitrogen, fill with just regular air until you can get to a place that can fix the problem/re-fill with nitrogen... no problem at all.

Edit - Fixed my mistake... I meant to say air, but for some reason I typed oxygen... all fixed 🙂

Dry air contains 79.02-percent nitrogen, 20.95-percent oxygen, 0.03-percent carbon dioxide.

So, Oxygen is not made up of nitrogen... it's late, but the above is what I was trying to get at... 😀

Considering the air we breath is about 78% nitrogen....no it is not a legitimate question...

Yeah, we breathe N2 molecules. Another molecule may be flammable. That is why I asked. But yeah, be sure to jump all over anything that might make you look smart.

It was a legitimate question... A lot of people ask that about Nitrogen in the tires... Especially because when you get filled with Nitrogen they put green caps on your tires... they think its some sort of warning... 😀
