Nitrogen or air?

    I got a coupon from my dealer for free nitrogen fill on my tires...do any of you do the nitro.... and is there a diff. from air? thank you.

    Nitrogen might be lighter since its pure. Air = mixture so you'll be getting lots of heavier crap in there.

    Go nitro since its free. An added bonus is that you can now tell your friends that you got your tyres filled with nitrogen.

    Also pure nitrogen has larger molecules so should you puncture your tyre, it won't empty as fast.

    Costco tires = Nitrogen. Ergo, all my cars have Nitrogen :)

    I thought it was supposed to be less likely to expand / contract with temperature variation. You also get cool turquoise valve stem covers....

    Last time I checked, air was 78% nitrogen, so there shouldn't be much difference. Maybe you're thinking about helium or sulphurhexaflouride?

    Me, I'd like to fill them with hydrogen and try a real burn out:)
     
  6. That's it. Also, there is no moister like you may get with compressed air. Basically, you are supposed to get a more stable/consistent air pressure which means better tire wear.

    I'm not totally sold on the idea and wouldn't pay for it, but if it's free,..........why not.
     
  7. That's it, right there. Pure nitrogen doesn't expand / contract based on temps. Motorcycle shocks are factory filled with nitrogen to maintain consistency. Whether it makes a bit of difference on car tires is anyone's guess, me thinks.

    Write 'this tire is more stable' with a special red sharpie
    on the tire. That will do it. We all know this nitrogen stuff is junk
    science... as BFM would say, 'piffle'.

    The sharpie is available from yours truly, natch. 39 bucks
    takes it. Shipping is extra. The pen has a lifetime warranty.

    Well obviously, thay have never heard of my pen. If they had, they would be using that.

    Jeff Gordon in particular needs to cross out where 'loser' is
    written on his forehead and write 'winner'.
     
  12. Jeff Gordon's head is already occupied with two words. "Turn left". It's written backwards so he can see it in the mirror.

    If you think filling your tires with nitrogen does anything plain old air won't, I have a Monster Cable I want to sell you. :D

    Since you're getting it free, go for it. But for daily use (read, not racing or flying at high altitudes) it doesnt really matter. Unless you're going from -40 to 25 daily, you probably wouldn't be able to notice it. And if you do, go get them monster cables NOW!
     
  15. :D

    Regular air is good enough. The big push for nitrogen around here is it's not supposed to leak out of the tires as fast as regular air is, since the molecules are bigger. So in that case if I fill my tires to 41 psi, when the leak down to 32 psi I should have nothing but nitrogen left.

    Fwiw I've been in the business for 26 years and I've yet to see any difference in any tire with or without a nitrogen fill, other than the pretty green valve caps.

    While Thor's sharpie post is nothing put pure win, it was this post that made me cry. :D

    Eh?
    Do you have a sticker referring to the fact that your tires are impressively filled with nitrogen? It only works if you have the sticker.
     
  19. tires filled with nitrogen stay close to the same pressure when hot. there is very little expansion. tires with air expand due to the moisture in the air. when i was in racin we used nitrogen because 1 lb. of "air" is worth 60 lb. of spring rate. if on a long run usin air lets say your tires heated up 10 degrees past inflated pressure you now just added 600 lbs. of spring weight. your set up just went out the window. if you do alot of long distance travelin nitrogen is the way to go. but hey, you got a free coupon, go for it.

    Thanks...Free coupon so why not. How much wold it cost to purge all the air out of the tires and fill them with nitrogen if I did not have a coupon? Now that I will have nitrogen in them do I have to continue to use nitrogen?
