Nitrogen?

Is anyone running Nitrogen in their tires and if so any luck with it?

 

It doesn't really do much, if it's free giver' , if you are paying extra don't bother.

 

It's a gimmick. The atmosphere we breathe (normal air) that you use in your tires is already 78% nitrogen. The only tires that truly need nitrogen is air plane tires so they don't pop when they go 40K+ feet up.

Welcome to the forum!

hahahahaa yeah I guess ass gas is free too! Just hope im not clogged up when I get a flat.

 

They say you get better mpg's and longer tread life running Nitrogen. Idk though haven't talked to many people that run it.

 

Going from 78% (normal air) to ~90% nitrogen in your tire isn't going to make much of a difference.

@Crom: the reason airplane tires are inflated with nitrogen is to reduce the likelihood of a fire after a tire blowout. Hot brakes + oxygen + chemical outgassing from the tire + severed hydraulic line...

 

I've never heard that before. But as it turns out I did some reading and we are both correct.

yeah im seeing more and more threads and topics online about it but wasnt sure on gains in truck tires. At least no one was wrong, LOL!

 

Yes, as Crom said... I use 78% nitrogen in my tires!

 

If they are going to pop at alitude it doesn't matter what air is in them. Pressure difference doesn't care about air composition they just care about it providing oxygen for fire after it blows.

 

You've convinced me bud, thanks

 

normal air is effected by tempature and nitrogen is not. I run HOT air in Texas (78%)

 

Airplanes put N2 in the tires because it has no moisture or oil init like regular compressed air would. At the altitudes the planes fly, any contaminants in the tire would freeze. When the plane lands, the sudden impact of the tire hitting the ground would heat everything and the tire would blow out, thus resulting in a crash. Also the expansion and contraction of the molecules are more uniform than a mixed gas.

The reason you would put N2 in a personal vehicle is to reduce the chance of fluid friction of the moisture in the air that could wear and cause corrosion on the inside of the tire and rim. O2 is a corrosive, and mixed with other impurities speeds up the process. People have been putting regular compressed air in their tires for a long time without a problem. But if you can get N2 for free, go for it. The next best thing is airing up with compressed air that has a moisture separator in the line.

 

O2 "permeates" approximately 3-4 times faster than does N2 through a typical rubber, as is used in tires, primarily​

because O2 has a slightly smaller effective molecular size than does N2.

my air compressor only gives me air

 

I filled mine with candy so my tires can be used as a piñata childrens parties.

 

It's so when they DO pop in the wheelwell after retraction (this is extremely common, when I worked at Douglas I got the daily "crash reports" and saw this 3-4x a week), the damage caused by the debris doesn't lead to a fire since the tire's nitrogen tends to purge the oxygen from the cavities.

 

And an extra 14.7psi is not going to pop an aircraft tire.
Particularly not the SR71's tires that are jacked to 600psi.

But ya... fill a tire at sea level and take it to the moon. That tire will contain only 14.7psi more than it did at sea level.

No tire is going to pop from altitude.
