It is slight. Air is about 70% nitrogen, anyway . Nitrogen won't oxidize the inside of your tires, and, if Dry, won't promote rust or oxidation to the rims like the moisture in air will. This effect is only slight, anyway.
Still, unless you carry a bottle of N2 around, if your tires get low, you will have to use air from a compressor from time to time, anyway, diluting the nitrogen. Even if the compressor has a good filter and moisture trap.
The Outside of your tires will Still be subject to oxidation, acid raid, ultra violet, heat, etc. That is the Business end.
Personally, I consider N2 in the tires snake-oil; OK but of only slight advantage. I wouldn't specifically look a shop with it or pay more for it. If your usual shop offers it free; Fine, use it. I don't believe in "nitrogenated" fuels, either.
Well, since the atmosphere is almost 80% nitrogen to start with, it'd be hard to avoid it. Some to to the extra effort of filling with "pure" nitrogen, although the advantage for a regular driver are slim-to-none.
Yes, nitrogen is more stable than air in tires.
It is not. That is why a lot of tire shops fill tires with only nitrogen.
Yes, Costo does inflate the tires with nitrogen for free.
no, however their is a shop that puts nitrogen oxide in low profile wheels and tires.
Many industrial supply companies will sell you compressed tanks of dry nitrogen that would be suitable for tires. For normal auto tires, regular air is fine, but nitrogen is often used to inflate the tires of race cars and airplanes.
They fill their tires with nitrogen.
No.

Nitrogen It's volume changes less than air as the tires temperature changes.
Nitrogen , check out this site, http://www.getnitrogen.org/ Typically, plain air. Nitrogen is used in high-performance racing tires and in large aircraft tires.
