    This is what I've read about it:

    Copied from:
    http://www.straightdope.com/columns/070216.html

    "Most tires are filled with compressed air, which when dry consists of about 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases by volume. Water vapor (humidity) can make up as much as 5 percent of the volume of air under worst-case conditions. Filling your tires with nitrogen mainly does two things: it eliminates moisture, and it replaces skinny oxygen molecules with fat nitrogen molecules, reducing the rate at which compressed gas diffuses through porous tire walls. That means, theoretically at least, that a tire filled with nitrogen retains optimal pressure longer, leading to more uniform tire wear and better gas mileage. The commonly quoted figure is that tires inflated to 32 psi get 3 percent better mileage than at 24 psi."

    I do not know if it is the same stuff my hubby had put in his work truck a dually.. but IT helps balance them.. In stead of calcium. Like they use in tractor tires.. works the same though

    Like I said I do not know if it was nitrogen but he had GCR put something other then Calcium in thme

    personally I wouldn't waste my money on it. I had heard about and had looked at it before, thinking it might be better in the long run for milage ect. But I dont' think that the difference is worth it.

    It is for race cars. What it does is it keeps the tires at optimal pressure under varying temperature because it's a less compressable gas then oxygen.

    Filling your tires with nitrogen helps them fill their bank account with money.

    For an extra 39.95, they'll rotate your spark plugs and install a new buckle on your timing belt.

    Calcium mixed with water is used in tractor tires to give more weight (not on the bearings) for better traction.

    A new product used is more envronmentally safe. But about 10 times more money.

    Nitrogen is a gas, and every time you take a breath anout 75 percent is inert nitrogen.

    Nitrogen is used at Bonneville for very high speed record cars. I don't think it's used in any other race cars.

    BTW, I use the sidewall maximum pressure number, NOT the pressure on the door well. That number is just for better ride.

    I have nitrogen in my tires. Came that way from the dealership.

    Much smoother ride, and I don't have to worry about the temperature changes through the year affecting my tire pressure.

    I get free refills on it for life too.

    The Race Car application also allow the circumference of the tire to remain constant or as it was set.
    To turn left the inside tire have to be less in circumference than the outside tires.
    Nitrogen helps keep these crucial setting constant and at the measurement the Crew Chief set.
    For street application it's overkill.
    Just check it regularly and use the free stuff.

    When you buy new and you get hydrogen included, how do you know if it the Hydrogen or the new tires?
    Did you put it in old tires?
    Have you taken the hydrogen out and replace it with air to do a proper A B comparison?

    There is a powder or liquid that is put inside a truck tire to help with the balancing.
    The larger tire is difficult to spin balance like a car tire.
    The powder is used to compensate for this.

    Appears I was wrong. nascar DOES use nitrogen.

    I believe formula 1 cars use nitrogen, I could stand corrected.

    No, Anapeg, you're right.

    http://www.acppubs.com/article/ca6291735.html

    "While the trend toward nitrogen inflation is relatively "new" to the truck and bus tire market, it has been long used in tires on Formula One, Indy, Le Mans, and NASCAR racecars; commercial and military aircraft; military vehicles; heavy off-road construction equipment; and the Space Shuttle. The Moon Buggy had its tires inflated with nitrogen. Also, the Tour de France bikes use nitrogen in their tires. Nitrogen is environmentally safe and non-combustible."

    Interesting technology.

    I was under the impression the moon buggy had tires made of some mesh compound. I must have either misread or misunderstood. Oh and Short Circutz, while your at it check the giggling pin on the laughing shaft. Grease for the high speed roller bearings on the muffler is critical, I prefer slipenfal lubes my self.
