I just got new tires for my wife's car. They're usnig Nitrogen too.
They put green caps on the valve steam to show its not air.

Yes, those green caps have proven to be much better at keeping the snake oil
inside the tire where it belongs.

On a side note...

- I learned a few years back that the CAP on a Schrader valve (the
common tire valve) is the PRIMARY seal. No cap, no promise of a good
seal from the valve.

- Green valves on bicycles mean the tire is "Slimed", and has a fiber /
goop sealant.

- Nitrogen DOES leak less than air, and is dryer than most compressed
air. While it isn't worth $59.95, some really good tire shops, and
places like Costco, provide it for free.

CO2, commonly used to quickly repair bicycle flats on the road, leaks
much faster than air!

- Anyone who's ever had an ice chunk in a tire can appreciate a "drier"
fill...
