Find a way to "dry" regular air and you'll get the same performance from it. Then again, tanks of nitrogen are pretty damn cheap and unless you're tire busting every weekend should last at least a season.

Many tire shops that supply nitrogen in large volumes (they have it readily available via a "generator") may have moisture issues, negating most of the benefit of Nitrogen. Please be wary.
