Hey Toolpants

What's up with the green valve caps? I got my tires at Costco and got the greenies too. I had my tires filled with nitrogen and thought maybe that's the way they tell that they're filled with nitro. Anyway, I went straight to Pep boys and grabbed some black caps; kept the greenies to swap out when I get them balanced,rotated and aired up.

The green caps are for Nitrogen. My local dealer has also started to do this.

Why nitrogen? I'm not familiar with this. Advantage?

I belive the answer to this is : nitrogen maintains the tire pressure for longer periods of time....

Apparently, nitrogen does not affect the tire pressure with changes in temperatures as much as good, old fashioned air.
