i keep hearing about people putting nitrogen in their car and how its a million times better than regular air that you get at the gas station. i was wondering is it worth the $20/avg that shops charge to fill up your tires?

From what i know, now a days the air compressors are 76% nitrogen.... i may be wrong... that just what I have herd.

i just read that whole post.

nitrogen tires are useless unless you actually need them for the extra performance.

T.awd is right air is made up of 78% nitrogen.. so whats the point !

I Still do not believe there is any serious gain in filling your tiers with nitrogen. Other than the minor factors that you may become a speed demon on a highway one day, or that you'll keep your tiers for the rest of your life....


Whats the point?

Nitrogen is great racing as often teams will adjust a car with air pressure and with Nitrogen there is less gain in pressure than with air that has moisture. But on the street for the most it is more a thing that while it may be better for some small reasons it will make little difference in any part of your life or driving.

One important thing to remember is that our Terrains and many other new vehicles on the road these days have TPMS's and just having regular compressed air which also has moisture can corrode the TPMS. I'm sure we all know how pricey it can get to replace one of those. For that reason, Nitrogen is used, as it wont corrode the TPMS.

And there are more reasons too.

i work in the aircraft industry and we use nitrogen on our aircraft tires and vehicles. its used on the aircraft tires to keep ice crystals from forming in the tire at high altitudes and it helps keep corrosion from forming in the rim.

Nitrogen is used in aircraft for the same reasons we are seeing it put in cars..The Nitrogen Molecule is much larger than the Oxygen molecule..so therefore it leaks out less through natural attrition...Hence more stays in the tire longer.

The heat to expansion rate is slightly less than oxygen, but not enough to make any difference according to Boyles Law...

Nitrogen in the car tire is more of a sales hype than anything...

In aircraft tires, it is more important that Nitrogen is used because it is inert and will not sustain any kind of combustion or fire..And being dry type, by means of dehydration while it's compressed into tanks, makes it good to keep moisture out of the tires and forming the ice crystals as mention here below by terrainnewby...

For the record: Our Atmosphere contains a moist; 78% Nitrogen, 21% Oxygen and 1% misc. gases.
