Nitrogen

Who has nitrogen in their tires? What is the advantage/disadvantage? What does it cost?

I forget where I read it, I think maybe it was a Car & Driver mag, something about the nitrogen gets rid of the moisture in the tire, I cant remember exactly.

I think air has moisture in it that expands and contracts due to temp change causing varying air pressures as nitrogen is a dry gas,set it and forget it.Also the molecules are bigger in nitrogen so you get less permiation (sp) thru the rubber which causes pressure loss.Someone correct me if I'm wrong.Gary

Nitrogen is 70% of air. The larger molecule thing is a myth.Using N2 in your tires isn't worth it unless you race your car where pressure is crucial for performance. Dry Nitrogen gas is inert and is not affected by temperature. This is my understanding( I work for an industrial gas company ).But let a science guy chime in.

Atmosphere is 78% Nitrogen already. Don't believe all you hear, save your money and effort. You asked for an opinion, that's mine.

All gases are affected by temperature as is water vapor. Since Dry Nitrogen does not have any water vapor in it the gas expands in a predictable way as the temperature varies. As you know water vapor content in the air varies by time. If you use regular air you have some amount water vapor in the air at the time you fill the tire. Differences in water vapor content from one filling to another makes pressure variations unpredictable. When you see the NASCAR guys add a half pound of pressure to a tire they are able to predict the pressure change as the tire heats up. With dry nitrogen this is very predictable. This helps them set overall spring rate and tire tread temperature at speed.

On the street you wouldn't notice the difference.
