some one emailed this link to me. I think its just like the racing air scam.

They're doing it at Belle Tire locations now, too. They call it "Nitro Nize."

Yea they've had a few commercials on it. Dunno if I want to try it on the Solstice or not.

The Costco tire center we go to uses nitrogen. Can't really tell any difference.

A shop nearby uses Nitrogen. . . reason is that it doesnt expand and contract as much as regular air. . . hence the better fuel mileage from not have to worry about tire pressures changing by the outside air temperature changing from season to season.

Ive been filling my tires with nitrogen for about 3 years now, I never notice any tires low on air.

I wouldn't think there'd be any difference, especially as normal air is mostly nitrogen anyway.

Having checked my thermodynamics textbook, there is only a minor difference in gas properties. Air, carbon monoxide and nitrogen (N2) have similar critical temperatures and pressures, and similar gas constants. The difference in tire performance is more likely to be influenced by the amount of gas used than the type.

Nitrogen is a very dry, stable non-reactive gas so that being for a performance wise it is very good because the pressure will remain more stable unlike plain out air that has moisture.

yah as he said a lot of it is lack of moisture

It's the moisture in air that effects the expansion.

Good ole Thermo. . . changed the way I look at everything! Esspecially the engine.

Anyone able to name the car that offered nitrogen-filled tires from the 'factory'?

ferrrari? i know they did or are you talking domestic?

vintage pseudo-production domestic.

Kno what- nevermind, it's so obscure that the explaination of the answer is likely the only thing that would take longer than the guessing.

And the answer is: Mohs.
