    Nitrogen

    In November I put Nitrogen in the tires on my company car, which is a SUV. I liked that the pressure didn't move much due to the outside temperatures. I noticed about 1 MPG increase in mileage in winter. The ride was a little smoother, and I have knobby tires on it.
    Today, I had a TPMS sensor put on my DTS, so I had them do the Nitrogen while it was in the shop. I can't comment on MPG yet, but the ride is unbelievably better.
    When I left the shop all 4 tires read 30, I drove 30 minutes home and all 4 tires read 33. The ride is very much smoother. Thought I would share the info with the board.

    Nice!! I was also told that it helps prevent blow outs and if they do happen they will not be as severe.

    I'd love to find someone in my area that offers it.

    Re: Nitrogen

    Costco routinely puts it in, in fact you have to tell them if you DON'T want it.

    I found it keeps tire pressures up, you don't need to top them off with air as often.

    Not a member; don't think they'll put in for non-member. If they do let me know and I'll go to one.

    Stu:

    Nah, you have to be a member. However, I have noticed in the last couple of months a whole bunch of GM dealers around here are advertizing it. In fact, I took my car in on Tuesday to get the left headlight assessed as to why it wouldn't go High Beam, took it back today when the new unit was in to get it installed, and saw all the brand new Nitrogen advertisement in the service drop-off bays that weren't there 2 days ago.

    You may want to check to see if the Caddy dealer in your area is now doing it.

    Re: Nitrogen

    The air in my tires currently has 78% of Nitrogen and I didn't pay anything for it.

    Re: Nitrogen

    Nitrogen in tires is the biggest scam out there. Itdltc is right in that regular air is already composed of 78% N. Nitrogen as a gas is inert, and won't support combustion. It is used in aircraft tires, etc. Obviously, if you're slamming unto a carrier deck and in engaged in high speed and mass braking with high temperatures, there is benefit to using nitrogen. But in regular car tires, the benefits are negligble. The tire retailers try to tell us that tires don't leak as much with nitrogen, but do the math, and you'll see that gains are virtually too small to notice. Anything to charge an extra $7.00 per tire of pure profit. As to ride comfort, I won't even comment. Pressure is pressure regardless of what kind of gas is exerting it. That's like saying Perrier water is wetter than tap water. Hey, it's your money.

    Re: Nitrogen

    Everyone has an opinion. I know it is worth the money to me not to be playing with increasing and decreasing tire pressures from season to season, nitrogen is a dryer, more stable gas that's less prone to changes in pressure due to heat or cold. Nitrogen will not degrade the interior rubber of the tire or corrode the wheels, since it contains no oxygen or water vapor. When I put $800 worth of tires on my car, an extra few dollars is not a big deal.

    Next thing you're going to tell me is that my car does NOT perform better and ride smoother after a good car wash.....

    Re: Nitrogen

    Of course your car will perform better after a car wash. Everyone knows that! Look at all that drag on the vehicle with the bird dropping on it.
    But seriously, Leo is correct about the dryer nature of nitrogen. Often the moisture content of air does cause rusting inside the tire, especially along the bead, thereby allowing those pesky slow leaks. To help keep mositure to a minimum, when inflating your tires, hold down the air hose end for a couple of seconds before attaching it to your valve stem. Assuming that the air in the compressor is relatively dry, you'll extract some moisture from the hose first and add less moisture into the tire.
