It can't hurt, but I don't think the benefits are there. Sure, there is less oxidation, but is that much of a problem?

Aircraft tires are often filled with nitrogen, and it is a big advantage. Aircraft tires and tubes are still made of natural rubber, and the air leaks out through the rubber. Pure nitrogen leaks out more slowly, and you need to add air to the tires about half as much. Normally you need to add air to your aircraft tires every month or two, and it can become a regular chore.
