Nitrogen in tires makes cars & truck go faster while getting better mileage
Nitrogen vs plain air gives a more consistent pressure in car tires, not that it's necessarily noticeable to most people. The reason is that normal air has water vapor in it; when the water vapor condenses, there's more contraction of the volume than that of an ideal gas undergoing the same temperature change - and similar in the other direction if there's actually liquid water being added to a tire (idk how, maybe someone didn't drain the air tank?) when the temperature goes up, because liquid water turns to a much larger volume of steam when the tire heats up. As I said, though, this really matters the most to racers, but it's a selling point, possibly slightly more legitimate than gold connectors for your fiber optic cables...
For tractors... ridiculous.
Especially when you're filling the tire with a bunch of water-based liquid!
