This is incorrect. All gasses "expand" when temperature rises. Read an introductory chemistry text to validate this.
To get 100% n2 into the tire you first have to get all the air out. If you don't do that, and merely fill a mounted tire with n2, and target it at 2atm pressure, you then have, not 78% n2 as you would using air, but 89% n2. So, if you pay money for this you are actually paying to reduce the non-n2 components by only 50%. You will still have the same quantity of O2 and moisture as you would if you put no air in the tires, other what was in them when you mounted them.

To me, there isn't any real practical advantage in using nitrogen air unless you are planning to do track racing.

yes you are right, that is why most systems do a double purge, you will still have an 02 content but you want it to be under 2%
to get the best results. the less oxygen the less moisture you will have. At my store i have always said the real benefits are
if you have chrome wheels or TPMS tire sensors, both get damaged from moisture.

Honestly, I don't know ir the cost of using nitriogen; negates it's supposed advantages. 
 I think it's a scam for typical motor vehicle use.

Exactly my point it is more stable and changes less than air  Even at same temp with temp drop it will be less. Just because the above post says they will re act the same it does not mean by the same amount.

N2 doesn't cost me anything & i know it's benefits so i use it. i never care what people believe, i do what i know.
P.S. Even if you believe in santa clause i am telling you he is not real.

If it expands/contracts less that is nice, if it doesn´t leak as much as regular air even better, if costs more well, have to live with it, it won´t kill me but an underinflated tire on a hot road full of bumps might...I guess you may call me crazy....jejeje...By the way, love this forum!! Thanks all for your feedback/input...It is almost ¨Tequila time¨...jejeje   
Im with you...i'm trying it also. Consider it a farkle...some you like, some you end up not liking.

I'm not going to argue with you on this point, but that is STRICTLY your opinion!

I'd run nitrogen in my tires just so I can run the pimp daddy green valve stem caps!

funny stuff
santas sled ride has reindeer's full of nitrogen... I think !
