Anyone try it ?? Talked to a guy from Florida over the weekend who is sold on it .... He had his tires filled on his 01 Honda and is boosting better then 40MPG ....


I wonder if anyone trailering with smaller tires at the speeds you run would benifit at least to a safety issues as they are suppose to run cooler ...

Air is approximately 70% nitrogen, 21% oxygen. The ad talks about comparing nitrogen to oxygen as if you were considering filling your tires with 100% oxygen or 100% nitrogen.


Hype, IMO. I've heard of people trying nitrogen in sports cars for track events, etc, and haven't been convinced of any significant benefit.


They don't seem to talk about the vacuum system you will need to evacuate all the residual air in your tires before you fill them with pure nitrogen. And if you choose to do this, I suggest buying medical grade nitrogen from a welding supply shop instead of investing in a system with membranes that selectively allows nityrogen molecules to take one path and keeps all other molecules separated. And you should note the ad's system produces 95% nitrogen (claimed) so you still have 5% other gases.


Furthermore, I would think that most tire failures are due to wear and road hazards, not inflation gas used. So how could you reduce tire failures by 80% just by filling your tires with 95% nitrogen?


Save your money for something more fun.

I read an article about using N2 in tires some time back. It wasn't any kind of sales ad. Very interesting, and most of it made alot of sense. I'm not sure how economical it would be for vendors, but in the long run, it would be great for drivers ! A safe, dry, inert gas that is very pressure stable in ambient temperature swings could pay out for most drivers. I would use it, if available. http://www.dieselplace.com/forum/smileys/Approve.gif

I hear N2 has the negative effect of drying out rubber. Not sure if it would do it fast enough though especially with a hopped up truck. By the time the rubber dries, the tires have no rubber http://www.dieselplace.com/forum/smileys/HiHi.gif

I have a full size N2 tank in my bed. I'll be using it on the beach to air back up.

I use nitrogen exclusively in my circle track car tires. Why? Because under extreme heat, nitrogen will not expand as much as air. My tires remained relatively stable in size, in a class of racing where 1/4" on the circumference (not diameter) could drastically affect the handling of the car.


IMHO it is not applicable to the street for mileage.

Trippin is exactly right. I used N2 in my rear tires on my race car. It is very stable and has predictable expansion(which in most cases is insignificant). Usually the air going into a tire has various levels of moisture based on quality of compressor. N2 is dry.


Now for general street use I cannot imagine why anybody would need it. Tire growth on our trucks is just not important.

At least the tires won't "Rust". http://www.dieselplace.com/forum/smileys/HiHi.gif

Commercial aircraft tires are filled with nitrogen due to the lower explosion/fire hazard. It is a safety issue for them, but not a big deal for us at ground level. Luke

The airliners use N2 in all there tires, like Trippen said it is very tempeture stable.


If it works on a airplane weighing 200,000lbs with landing speeds of 170mph and stoping in only 5,000' to 7,000'. It probably would be ok for our truck tires.http://www.dieselplace.com/forum/smileys/HiHi.gif

Why not Helium to lighten our trucks??? http://www.dieselplace.com/forum/smileys/HiHi.gif

Many years ago when I worked around fighter aircraft they used nitrogen in the tires on F4's and some big helo's. Thye told me that the reason for it was that pure nitrogen expands a bit less with heat and that the larger molecules of it tended to seep out of the casings of the small hi pressures tires (some as high as 300 psi and more) more slowly too. On B52H back then, at max TO weight you could have 365 PSI in a tire. You should hear one of those things pop when antiskid failed on landing and tires locked up. It sounded like a very big cannon and could do some structural damage too. Edited by: snoman

A tire shop in my area fills all new tires with nitrogen like every one else said it is verry stable and with it being dry you get less or no corrsion or rust on rims reducing the chance of bead leaks
