Several benefits.
The first being that Nitrogen's properties are different from Oxygen in that when it gets warm (from hard driving for example), it does not expand. Thus, you can set your tire pressure, and it will stay that, whether you're on the track, or letting the car sit in freezing temperatures.
The second benefit is that Nitrogen molecules don't seep through rubber, as Oxygen does. Thus, you are able to hold a more steady pressure for a longer period of time.
And lastly, Nitrogen is an "inert gas". This means it is not flammable, as oxygen is. For this reason, Nitrogen is safer, and used on most competition cars, such as NASCAR.
So to sum it up, it holds pressure better, and doesn't go "boom" if something bad happens to the car.
