If your rig can do 150 mph with a dragging brake, then fold the wheels up into a closed box, nitrogen is a must. Otherwise it's a waste of money. This is based on experience as a landing gear engineer at Boeing!

Thank you for bringing in some science. Now for some human engineering.

If you're bringing your car to the track and all of your support gear. Which is the easier way to air your tires, blow dust out of things and anything else you'd use compressed air for. Lug a compressor of some sort and hope you can find power for it? Or bring a 2600 PSI nitrogen bottle, regulator and hose?

Yes race cars fill their tires with nitrogen. But you should ask yourself: Why?

Some good posts some based on belief in marketing more important than facts. As a tire engineer here are some facts.

Why do tires loose air? Warning MATH and SCIENCE are involved

How to get dry air for your tires

Inflate with Nitrogen and there will be MAGIC

Bottom line
If it's free then I say use it.
Personally even though I have access to Argon and CO2 in my shop and have had N2 in the past I never used these on my street tires (car, truck, trailer, or RV)
