Good Morning,
I just got back from a week long seminar in Effingham, Illinois. I had the pleasure of being seated with a fleet service manager and we discussed air vs nitrogen in tires. He said that you don't see the pressure change in the tire as you would with air and that extends tire life. He also commented that on my new front tire on the tractor and running gear I should use nitrogen and it would also reduce the cracking on the side wall of the tires over time. Any thoughts on this from the forum?
Danny

Dry air already contains 78% nitrogen, about 20% oxygen and a few other elements. When you have to add, you then need to find a source for nitrogen or begin to dilute what you already have in there.

it will help a fraction of a percent on a race car at 200 MPH. Every little bit helps. ON an automobile or tractor, it has little value.

There was an extended referenced discussion over on New AG Talk three days ago. http://talk.newagtalk.com/forums/thread-view.asp?tid=189759&mid=1386111#M1386111
There are benefits to aircraft and paved track racing that don't affect ordinary cars and trucks. The biggest benefit is to the profit of the tire store selling N for filling.

I have enough problems keeping (cheap) air in my tires.....seems they are always flat on at least one side!

Dan - As stated, I agree. There is no advantage to nitrogen. It is just a fad and way to get money from the customer. If the tire stores have a dryer on their compressor, then there is no advantage. _ AL

As someone who used to put nitrogen in aircraft tires from time to time, for your car, tractor, and truck, its Bull$#@*.
The two reasons for it in aircraft is related to water vapor. Water condensing out of the air and then freezing can cause the tire to become out of balance. Also many aircraft rims are made of magnesium and corrosion is a big problem with them.
Tell your tractor shop that when you get mag wheels on your tractor that you will consider the nitrogen.

Wonder what marketing brain child came up with that one. I thought it had run its course by I see its still out there. I know people who bought into it and go back to the tire store for more nitrogen when they service there tires. What a bunch of crap and thats coming from me an A&P who uses it everyday on the job for Aircraft tires. Its only used because its a dry gas and typically transport type aircraft need higher pressure than you can get from an aircompessor so you service from a high pressure bottle. Dry air will give you the same effect.

the nitrogen craze started with a legitament cause,aircraft tires on the large a/c that on landing all the tires are cold soaked to as much s -20 deg.below from long high altitude flights.on landing and even normal braking,the temp.goes from -20 to as high as 400-600 degrees in a matter of seconds.the coefficent of expansion of nitrogen is no where near that of air.also fire brick was right,nitrogen (dry) also very much lessens the corrosion factor in the magnaloy rims.in theory,this a ripoff especially for tractor tires as well as car and truck tires..
