You won't save much weight, air is 78% nitrogen anyway.
The idea is that Nitrogen keeps tires both inflated at optimal pressure longer (fat Nitrogen molecules don't seep through the tire walls as easily), and the moisture content of the air is reduced, but there haven't been any scientific studies to prove that it works to improve gas mileage. You shouldn't see any difference from checking your tires when you fill up with gas, and re-pressurizing as needed.
Good thought though, at least it's better than these HHO scams

As long as you keep the tires properly inflated, no, you will just be wasting money by getting a $20 nitrogen fill up. Also as noted above, air is mostly nitrogen anyways.

IF you or your family are members of COSTCO its FREE and its all they use! Nitrogen doesn't expand when hot like regular air does and it doesn't allow the tire to dry rot from the inside like regular air does. Its better for the tires but you won't see a difference at the gas pump.

No point in it for your car if you just want to save gas though, air is free almost anywhere you go. Corrosion shouldn't be a problem for quite a few years, even with steelies. I think most people would be getting a new car long before corrosion became an issue.

Plain and simple, the main benefit of nitrogen fill ups is that your tires remain fuller, longer. If you're not the type that checks them every other tank or at least once a month, then it may be to your benefit to get them filled with nitrogen.
If you have the TPMS on your car, then you can check your tires with the push of a button and fill them as needed.
