Wow! Nitrogen is regulated in CA? Nitrogen? 78% of the air we breathe is nitrogen, and to regulate it to that extent seems a bit extreme, IMO.at our dealer we had a big tank and a special regulated digital screen and you had to hook up all 4 tires at once before it would start filling. good idea, but the screen almost never worked correctly and it freaked out all the time.
"Careful putting nitrogen in those Challenger tires there, Fred! We don't want to have any nitrogen leaking out into the atmosphere!"
