Compressed air is 78% nitrogen anyway. Nitrogen filled tires still require filling and bleeding as the environmental temperature changes. I've seen better performance but it's not like your tire pressure will remain the same if you are driving in 80° F or 40° F.
For my driving environment Nitrogen is a waste of money.

NItrogen is used by racers because the expansion coefficient is less. It allows a more constant pressure in extreme temperatures. In racers a 1 lb difference in pressure matters. For the average car on the street it's worthless.
If you are a Costco member, their tire shop will replace the air with nitrogen for free.
