Nitrogen in tires?
 

Got my Coupe w/sport pkg. today. It has green caps on the tire stems. Does that mean tires are filled with Nitrogen or are they just pretty green caps. I gotta green "tool", but that's a whole different story.

Yes, they're filled with nitrogen.

That or a leprechaun fornicated with your valve stems :ugh2:

Yes, they are filled with nitro.

I'm gonna go with this

:koolaidwall:

Yep that's nitrogen!

Butt, why are my caps green? :yum:

Thanks for the info guys.

I guess I'll try and keep N in the tires then. As little as I drive this thing I think the tires will get pretty old. But then again, I'm starting to invent reasons to drive. Too damn much fun! (Like: "I gotta run down to the store honey, this bar of soap has a torn label and I need to return it":driving:.)

Mine came with Nitrogen filled tires too, but once they go low I'm not going to keep refilling them with nitrogen, its inconvienant and most likely not even that effective anyway.

^^^tests show nitrogen is actually more affective then O2 lasts longer and has a better density, but it is a PITA when you need tires filled.

The dealer should do it for free for you. But in 9 months which include half Fall, Winter, Spring and half of Summer and I haven't had any issue with the Nitro in the tires.

With the regular air in tires of my 350Z I did have issues with the different change of seasons.

My JDM 300zxTT 2+2 (limo) had the same issues I was constantly monitoring the tire pressure. The 370 no problems yet going on 3 months......

do they all come with nitrogen? no green caps on my stems. :(

Mine did not come with Nitrogen filled tires but I will do it. I had it on my 350Z and checked the tire pressure only every 3 months it was stable with Nitrogen. With air you can check a month after filling them and already you lost 2 to 3 PSI.

I got my Nismo this summer and it comes with Nitrogen filled tires, but i do not have green caps...
