    I had nitrogen put in my tires at the dealer today. I then took a salesman for a slightly scary drive and then drove home. Altogether I was in the car almost an hour and only one back tire moved 1 pound.

    Nitrogen is great for less fluctuation on tire pressures, also you won't get the moisture inside the tire that ruins your tire pressure sensors from air over time and also less leakage and better gas mileage. Nitrogen molecules are bigger then air therefor less leakage.

    Im sure most of you know that NASCAR uses nitrogen mainly for less time getting tires up to pressure.

    At my dealer all SRT vehicles leave with Nitrogen in tires, sop, unless buyers say no, plus the metal green topped nitrogen marked caps on valve stems...

    My father was a big time executive at Good Year, I am not sold on it. but I am glad you like it and gave feed back. They would brag about how much money they could make on it.

    Its great to have different opinions, I did get it for free and on the way there my tires moved around 3 to 4 lbs versus 1 lb on only one tire on the way back so I do know it works.

    I use nitrogen as well and have for several years. With the summers in Vegas heating up the streets to frying pan temperatures, I've noticed that my tire pressure stays relatively consistent. I also get it done for free so that helps in my decision making process.

    All we have to do now is get Tammie hooked on nitrogen and everybody on the site will get it then.:)

    Nitrous oxide works for me.

    nitrogen is great if you are overly concerned about tire pressure fluctuation but if you are the average user and you are paying for it, it is a waste of money. My employer did a study on nitrogen for our fleet and although they found 1 to 2 lbs differences the cost was not worth the benefit. If you are low a bit or stuck, once you add air it compromises it and then you have to empty the tire an refill it.

    Always choices, great you like it as it does work but more hassle than benefit

    What i like is no moisture in the tire that air causes and less chance of seepage because of bigger molecules.
    I did get it free and if your low and only can find air, yea but the Dodge dealer I get it from will drain it and refill it for free so Im good.

    I found a place that'll put in cold air, and it's ten percent cheaper than actual nitrogen, surely that's a bargain? Of course, I had to let 'em drive it over the weekend, to make sure it 'took' and wasn't leaking. They're running late, but hope to get it back soon.

    Compressed air is 80% nitrogen, and if the compressor has a drier there is no moisture in it, close enough for everything we use. Have never seen any improvements of one over the other,

    Do the math:

    p V = m R T (1)
    where
    p = absolute pressure (N/m2, lb/ft2)
    V = volume (m3, ft3)
    m = mass (kg, slugs)
    R = individual gas constant (J/kg.oK, ft.lb/slugs.oR)
    T = absolute temperature (oK, oR)

    R for Nitrogen = 1775
    R for Air = 1716

    in Imperial Units
    (ft lb/slug oR)

    Not real sure what that formula is representing, are you saying that the oxygen content of air is basically equal to the nitrogen content?
    Absolute pressure x volume = mass x individual gas content x absolute temperature divided by 1???

    I think Catless is saying to solve for P (pressure) and you'll see that given normal temperature fluctuations, that the pressure won't change that much.

    and if you are doing the calc those R values are for imperial units.

    or just google the pros/cons and see for yourself lol, but don't think you'll find anything that wasn't already mentioned by these fine people in this thread.....Yinz know your stuff n'at (you Pittsburgh folk know what I'm saying...the rest of you jagoffs just keep on moving along, nothing to see here)
