Has anyone used nitrogen to inflate their tires. What are the advantages of this or is it a bunch of bull?

 

x2 on this one for people who have experience. All I've ever thought is since NO2 isn't as temperature sensitive, you don't have to worry about under-inflated tires in the cold. They hold constant pressure better in a wide range of temps.

 

I dont have first hand experience, but Nitrogen is less dense than air, so, in theory, should help gas mileage too

 

It is a load of BULL. I had nitrogen put in my BFG's when I got my MT classic II wheels this past July. Yes the pressures don't change as often than using compressed air-HOWEVER the pressures WILL change some as WITH regular compressed air just not as often. I put compressed air back in my tires as not too many places around me have nitrogen plus paying to inflate my tires seems like a waste of $$. Also the driving around negates the fuel milage benifits anyway!!-Just my .02

 

the air you breathe is already 78% nitrogen, 21% oxygen and 1 percent other gas. The only issue is that the air tends to hold a lot of moisture (water vapor aka humidity), which can add up to 5% of the volume of the air. By going with pure nitrogen, you are eliminating most of that humidity and getting rid of the oxygen which tends to fluctuate more with temperature change.
Also, the rubber in your tires is semi-porous, which over time allows the smaller oxygen molecules to escape...nitrogen molecules are larger (albeit only about .3 times larger), so they keep your tires inflated to the proper pressure longer. Oxygen will permeate (basically seep through) through the rubber 3-4x faster than the nitrogen will. Really, you aren't seeing a huge benefit just because you are running pure nitrogen, you are seeing the largest benefit because you are getting rid of the humidity and oxygen inside of the tire.

Is it worth it? That is for you to decide. I run it because I have an endless supply of compressed nitrogen at work, and have a large bottle of it in my work truck...so it is just as easy for me to fill my tires with nitrogen as it is for me to drag my air compressor out.

 

Bingo! To me its a crock of s#!t.

 

i have it in my tires, but theres no way in hell id pay to get them filled with nitrogen

 

Nitrogen is used in race applications because of the resistance to change with temperature swings. Civilian (lol) use is a waste of money.

Has links to a handful of articles which may or may not have more scientific basis than the armchair experts around here.

 

OK, I will chime in here. Seems like the change of pressure has already been covered so I won't beat that to death. I had the tires in my 09 Lariat inflated with nitrogen, as I had the tires on my Harley done when they were new. I did it because the ride is MUCH better. So, no matter what all the others say, I did it for the ride.

 

x2 used it in my race cars, i wouldnt bother puttin in my street tires

 

Can you say ssssssssnake oil?

 

The dealership that I bought my truck at uses Nitrogen in the cars/trucks they deliver. The tires also came with an additional warranty from the dealership for two years. If the tires loose air the tire will be fixed or replaced regardless of tire tread and milleage (non pro rated) at no charge. Basically, the nitrogen is supposed to make the tires last longer so the dealership gaurantees the tires. I should find old Wranglers and see if the warranty works. I should read that garantee, i really did not care when I bought the truck.

 

well if the dealer is warrantying the nitrogen id bet they would have a gauge to see the ratio of nitrogen to their elements in the tire...like i have for raceing too ensure proper nitrogen levels in the tires. and they would see a lot more air then nitrogen in there and void your nitrogen warranty

 

If you live in a very cold climate nitrogen will keep your auto tire psi sensor gauge from pizzing you off every morning when you start your ride and it warns you that the tires are all low. So people I know get it in winter for this reason, and this reason only. You don't get the wild contrast with temp changes.
