| wallygator310 | I remember a post about nitrogen for the tires and how it works better than regular air. Found this on the web and I'm thinking about it as it is a reasonably inexpensive alternative to air for home use in our tires as compared to the industrial units which cost thousands.

| Fat Pat | I guess I don't "get it"!! What is the advantage of having nitrogen in your tires? I think the space shuttle uses nitrogen in it's tires and the tires are only good for 1 (one) landing!! |
| MDProwler | With air the pressure is relative to the temperature. The pressure rises as the tire heats up and lowers as it cools down. Nitrogen does not change with temperature.
Do you know anyone in the Air conditioning/refrigeration trade? Most techs carry nitrogen on their trucks.

| ALLEY CAT | Also, I might add,,,,your inexpensive home air compressors probably don't have moisture filters installed in-line. Thus, you most likely are adding moisture into your tires,,,and your air pressure sensors 'do not' like moisture. Go let the air out of your tire and see if water vapor blasts out during the escape,,,then you'll know. While moisture filters aren't exactly cheap,,you might want to add one to your home air compressor system, JMO. |

Harbor Freight has them for under $40. I have had mine over a year and it works great. A must for painting. |
| Fat Pat | I have a class 8 truck air dryer (with dessicant) adapted to my (not so inexpensive) air compressor. |
| wallygator310 | Depending on the tires and normal pressure of them, driving any distance (depending on temps also) your tire pressure may expand by 2-5 lbs more or less. Using nitrogen reduces this increase to little or none and also like the others have said, the reduction of moisture will be essential for long running of wheels and tires to keep them from degrading due to moisture, etc. Of cours not everyone is interested in this subject or cares enough about it to change. I just thought I would bring it up to the top again as I remember that someone spoke about it some time back. Wally |
| Karesel | Isn't the air we breath something like 75+ percent nitrogen so why won't it expand if it's pure nitrogen but does when there is oxygen and carbon dixoide included? Is there a physics major around on here.... |
| MDProwler | Typically 78% nitrogen , 21% oxygen, 0.9% argon, 0.03% carbon dioxide with the remainder being a mixture of trace gasses plus water vapor. |
| jforbes | Take a look at this site -- http://auto.howstuffworks.com/question594.htm
kind of explains it. Basically, what really at work is the ideal gas law (pressure is directly proportional to temperature). However, I personally don't see that it really makes a whole heck of a lot of difference. It might save a little tire wear, but in the long run I kind of doubt the cost benefit is that great.... air is free |
