Nitrogen in your 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...

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.

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.

But it does add value when doing leak tests.
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.
