What is Nitro Air Pressure?

Can anyone tell me what is the difference between nitro & normal air pressure? Is it ok for road use? will tyre wear longer then normal air? Thankz....

Can anyone tell me what is the difference between nitro & normal air pressure? Is it ok for road use? will tyre wear longer then normal air? Thankz.... pressure is pressure, doesn't matter what maintains it(other than compressabillity). the reason nitro is used is because it's not affected by change in temperature. it won't expand when hot, thus increasing tire pessure. makes everything more stable and allows the tire to remain at optimum pressure no matter if it's cold or hot.

To add to that, it is generally believed that you set tire pressure with nitrogen at the pressure you want when the tires are up to temp. With normal air, you have to set the pressure lower, then check it when the tire is at temp because the pressure will increase. So, if you set pressure to 30 psi cold so that you get 34 psi warm, then you would set nitrogen to the 34 and leave it at that. Does it really work that way? Couldn't tell you....never tried it.......IMO it's not worth the trouble unless you're at the upper end of the racing echelon. Plus, there's so many debates about the 96% vs 99% nitrogen, and you can't really trust what you're buying when you go to the regular tire dealer and have them fill your tires.

thankz peepz...

It's not really the Nitrogen that's important, it's the moisture in the tire. Our atmoshperic air is around 78% nitrogen, so your tire mostly has nitrogen in it already. Now if you use nitrogen in your tires and are sloppy with the install by getting too much soapy water in the tire when mounting the pressure rise in your tire will be excessive, regardless if you've used pure dry nitrogen. I use nitrogen at the track, simply because I buy a medium size cylinder of it; it's more compact for my already cramped trailer. I get about 4 psi rise with nitrogen in the rear tire. Most tire manufactures are recommending hot pressure settings now, so if you use nitrogen or air just get your tires stinking hot and set the hot pressure. Dry atmospheric air has almost the same pressure rise as pure nitrogen, so if your paying big money on nitrogen fills then put your wallet back in your pants, it's not really worth it.

I thought all gases expanded when heated.

Well...they gave me for free...:crash

I'm no expert but I have nitrogen in my FZ1 for the street and plan on doing it for my R1. I did it because I rode all year in Chicago where in winter you psi drops drastically wen left to sit over night. And since the road never gets warm and my tires didn't heat up the nitrogen was the best bet. It's a denser gas and it's effected as easily to outer temperature change as is regular air. I have a nail in my rear right now (not riding) of my FZ1 and the tire is still a brick after months of being in there (the tire needs to be replaced because of wear). I know about the moisture thing and can understand that and AGREE. But again, I ride no matter what. And I want the nitro because it just works out better for my riding habits.
