Ding ding ding!! All these posts and only one right answer. For the rest of you, we have some lovely parting gifts. Johnny, tell them what they've won...
Just a slight error here. ALL gases are effected by temperture, Charles Gas Law. Some chemistry 101. The effect in compressed air is from the moisture as stated earlier in the thread dry air will show less change of pressure then compressed air without a dryer. How many times have you seen someone discharging an airline and a stream of water shoots out. But the reality of all of this, is it really needed. I check my tire pressure every week while I am washing the car.
Well we did an actual test with both -
Regular pump air -
30PSI in the tires, COLD.
Did a 10second burnout.
36PSI in the tires HOT.
Nitrogen-
30PSI in the tires, COLD.
Did a 10second burnout.
30PSI in the tires HOT.
I work at a speedshop that shares a building with a tire shop....I was SUPER skeptical about the nitrougen when they got it....Needless to say, I will run it in all my cars from now on.
It really does work.

99% of the shops out there pushing nitrogen don't even know why they're doing it--except that people will pay more for it. That said, since most shops don't worry about the quality of their shop air, nitrogen isn't a bad choice to guarantee low moisture content. It would be cheaper for shops to put dryers on their compressors....but then they couldn't sell it as something special, could they?

om-mm..... I don't think he was serious about that.

Does the A-Team do that for their shows? They shoot the tire and the tire explodes, flipping over the car in flames?
For a street car no one would know the difference. And you don't need different valve stems for nitrogen. 
Like it has been said, nitrougen has no moisture in it so the pressure wont fluctuate as much. Race teams do this to keep the pressures more constang, but they still go up in pressure alot more than you think. For a street car though its not worth anything.
