Nitrogen in your tires??? So we drop the GTO off at Beck and Masten North this morning to fix a leaky steering rack, and a bubbling spoke on the steering wheel, all under warranty, and the service consultant gets down on his knees and starts inspecting the tires:
"Hmmm looks like some uneven wear here... sir, have you ever thought about putting nitrogen in your tires?"
I smile and simply say no thanks, but I wonder how many people they hook by casting that line out there...
If I woulda known that I could charge people for air, screw college and working! haha...

so then we should all pay to get our tires nitrogen filled since god forbid I fill up my tires once every few months for free, or 50 cents... lol If your leaking enough air to where you need to use this nitrogen stuff, probably have other issues perhaps? I lost about 4 psi in the last 9 months in the Z06, does this mean I need nitrogen?

im pretty sure it has to do with temperatures of nitrogen vs. oxygen, not with leaking, tires shouldn't leak at all no matter the gas in them, gas can expand or shrink because of temperatures but it shouldn't escape

It's all about making a high margin sale.

How much was the fill - $19.95? $24.95? Cost is pretty low for them. Nice margin in it.

So I guess they put Nitrogen in tires so they don't leak out as fast.

Air is mostly nitrogen.
They use Nitrogen in tires instead of air because it won't have the moisture. Makes little sense to me on a street car that sees moisture on the outside of the wheel/tire on a regular basis. For the most part it boils down to a gimick. Much like drilled rotors.

well this what i found, i don't know who's correct but i have heard this from a truck driver before.
The thinking is that nitrogen's larger molecules prevent it from seeping out of a tire as quickly as air. So inflating tires with nearly pure nitrogen - which has been done for years in race cars, commercial airliners and long-distance trucks - allows them to retain correct pressure longer.
Pressure is vital because a properly inflated tire is a safer, more efficient tire. The National Highway Traffic Safety Administration says most drivers can improve gas mileage by nearly 3 percent by keeping their vehicle tires within the recommended pressure range. The government also estimates the nation loses more than 2 million gallons of gas every day due to underinflated tires.
Enter nitrogen. Chemical No. 7 on your periodic chart of the elements. At anywhere from $2 to $10 per tire.
