I was concerned this strip might be too esoteric. Tires inflated with nitrogen have little blue stem caps. I see more and more of these as the cost of gasoline goes up. The idea is to get better mileage because you retain the correct inflation of the tires. And it’s cool because race cars use it.
I wouldn’t expect pure nitrogen to make any difference; it is, after all, the majority component of air, and it is slightly lighter and smaller than oxygen atoms & molecules. Is it that tires are less permeable by nitrogen?

The only stem cap I’m familiar with is the green one that is put on bike tires after they’re filled with Slime.
