The advantage of N2 is that it comes from a tank.
Air from an N2 tank is dry. Ambient air has a lot of moisture. If you could
provide regular air at 0% humidity, it would be just as good.
It is the moisture that affects the predictability of how the tires behave
with temperature, but I doubt anyone not in a racing environment would ever
notice.

Since good old air is almost 80% N2, I would venture to guess the
thermal expansion of N2 and air are very similar.
