    Default Putting nitrogen in you tires....

    Today my dad went to go buy some new tires for his truck. When he got them the person who put them on asked if he wanted to put just regular air or nitrogen in his tires. He said it would cost $6 per tire to air it up with nitrogen. He didnít do it because he wanted to see what the pros/cons were, and plus he had never heard of that. Do any of you have any idea about this?????

    I haven't personally done it.

    The hype is that Nitrogen doesn't expand or contract from temp changes as much as regular air.

    This is supposed to translate into better gas mileage and longer tire life.

    Not a believer yet. I need more evidence than a salesman trying to sell me on it.

    Here is a newspaper article about the practice

    Sounds like a great idea-for the guy selling nitrogen. Regular air is 79% nitrogen and is usually free. What benefit does 100% nitrogen have for tires?

    I recently purchased new tires at COSTCO. They filled my tires with nitrogen at no extra cost. When I inquired about it, they advised that it doesnt expand/contract like compressed air does with temp changes, and that the nitrogen molecules are larger than air molecules (isnt air 73% nitrogen??)- that cast aluminum rims (like mine) dont leak as badly with pure nitrogen.

    It was no cost so I didnt bitch........

    I am going to have the Mustang's tires filled with synthetic air. The Stang's got mobil 1 synthetic oil in it now, and I gained about 1 mpg despite playing my favorite piece of classical "music"... right foot and pedal symphony in Ford major!

    If synthetic oil improves mileage and performance, imagine what synthetic air will do!

    SPFD rum has it right: scam.

    The miniscule difference between pressurizing tires with nitrogen or good quality dry air air isn't worth a dime. The biggest difference is that nitrogen from a commercial gas cylinder will be drier than air from a crappy gas station compressor. There will be some insignificant differnce in how the inside of the tire and wheel oxidizes based on moisture and oxygen in the fill. Is it going to make any difference over the life of your tires in normal use? Probably not.

    Air is already mostly nitrogen and, unless you conduct your nitrogen tire fill in a nitrogen filled chamber, you're still going to get a fair amount of atmospheric air in your tires anyway. Not to mention you'll be contaminating them every time you top them off with air in the future unless you plan on going back and paying for nitrogen every time...

    So does this mean that I shouldn't take the Spring air out of my tires and have it replaced with the Fall air?

    If you use hydrogen you'll get more bang for your buck.

    Seriously, racers have been doing this for years. The key is dry. DeputyMarshal is on the money - good dry shop air will do just fine. Unless you have millions of dollars riding on crossing the finish line first, it probably isn't worth the added expense. If it's free, go for it.

    There's been a few radio ads for various auto shops around the area, spouting use of nitrogen for tire fills. I'm not convinced either - for now.

    Like several others have said, if you're planning on running this weekend's NASCAR race then go for it. A Quarter-pound tire pressure change will make a big difference getting off the corner at Martinsville but the cul-de-sac is muce more forgiving. Don't waste your money.

    Most of the shops around here now provide it free with new tires. The Nitrogen molecule is larger than O2 molecules, so it has a harder time escaping, thus even with its property of being more stable with temp fluctuations it also keeps your tires at a full pressure longer. It is not a scam, but if they charge you 6 bucks a tire it is not financial worth it either.

    Only fill your tires on either days of the Equinox. Equinox air is well balanced,

    All other air has either too much or too little light in it.

    And don't get me started on Dark Suckers, that is a whole different thread that one.

    Zzzzzzzzz... ppppplloooooppppp........ there went the line and sinker. So I'll bite.

    When does your tire have too little light in it and what are the ramifications of not having enough light in said tire? And how many dark suckers does it take to have too much light in your tires?

    First off, Ramifications are a very nasty thing, ifications occuring in male sheep are painfull and if observed a vet should be called immediately.

    You are confused on the second issue as well. What we are considering here is the UV content of the air due to over exposure to light.

    Everyone knows UV light will break down rubber if given long enough. Say 250 years or so.

    Why take the chance of it happening to your tires.
