I had an Ivy League student complain to me that it cost $20 to put air in one of her tires. The mechanic had claimed she needed to use nitrogen.

I asked her what the earth's atmosphere was composed of.

It took her a bit, but she soon figured out that they just took her for $20.

to be fair, filling with nitrogen specifically is a thing, IIRC - I think the lack of water is the advantage?

But yes, she's probably a moron that doesn't even know how to just go to a gas station and use the compressor herself.

Running the air through a dryer, which any good compressor should have anyway to protect the tank and air tools, would solve that.

The selling point is that the nitrogen molecule is larger than the other atmospheric gasses, so it seeps through the tire slower and is less affected by temperature changes. Basically, a great idea for airplanes, but just a money grab for passenger cars.

Nitrogen molecules are larger and less sensitive to pressure changes induced by cold weather. It’s great for tires when there are temp fluctuations.

It keeps the damn low tire pressure light from glowing,
