I've serviced aircraft tires with nitrogen for years and never considered using it in my truck tires. Maybe I need to consider it?

We use it in aircraft because it is dry and inert. No moisture to freeze at 41,000 feet and in case of hot brakes, it won't burn. A side benefit is natural rubber tires maintain pressure a little better with nitrogen. Automotive tires are not made of natural rubber so maintaining pressure is not much improved.
