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...

I just called my local Nissan dealership and they said they don't do nitrogen fills. Aren't all of the dealerships supposed to offer it?

Ended up going to Costco down the street for a free fill. I was down to 31psi all around.

Crap...any issues mixing o2 in the mix? Had green caps, but was a few pounds low in each so I topped off...

^^
Shouldn't be any issues mixing the two. I wanted to have them completely bleed out my tires since I didn't know if I was filled originally with nitro or not. But it was an hour wait so I'll have to go back. They do it for free for all members. Or you can top off yourself as well if you just drive up.

So Costco will bleed them dry and fill them up for free?

I wont be refilling with nitrogen again. I think its a total waste to spend money on that...

Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.08% by volume of Earth's atmosphere. That means in the air we breathe....Dont waste your money on nitrogen.....

My tires came filled with nitrogen but I have blue caps!

Both of my 370Z' came with Nitrogen, but my Titan didn't.

Did they sold you the car with filled Nitro tires? Is so that is so BS, they are suppose to service your tires if they get low. However, you might have a leak if your tires have Nitro for them to go down to that PSI.

I wouldnt spend 100 bucks on it.. but considering my dealer did it, and maintains it for free.. ima stick with it.

i'd rather have 95% nitrogen than 78% nitrogen mixed with moisture.

If my dealer did it for free, then I would get it done... but they wont do it for free....

does the nitrogen mess with the tpms sensors?

I have had my car for close to a year now and I have not hadto top off the tires as of yet. So either the nitro is that efficient, or my tpms sensors are jacked :eek:. Come to think of it,I got an email recently asking me to have the tires "serviced" at my earliest convenience. I have not had any issues with flashing lights or anything,but I cant speak for everyone. :twocents:

Well..you really dont have that much temp. change from season to season in your part of the country..........

[QUOTE=FERRARI;851201]very true, but in fairness, this car has seen its fair share of canyon runs, and "spirited" speeds. Along with the fact the vehicle sits M-F,I am surprised I dont have bald spots on my tires.

when i got my new tires the shop said they did not recommend nitro cause it messed up the sensors

question bump

:iagree:

uhmm thats kinda a load.

Nitrogen in my tires never had issues. Not in the 90+ summer, or the current 20 or below cold. Not at the track, or the mountain runs.

As someone said, air is about 78% nitrogen so if nitrogen ***** up your TPMS then were all screwed.

hmm

I've been working on transport category aircraft for over 30 years...we use nitrogen in the tires on large aircraft. The same benefits a four foot tall airliner tire I couldn't see in the small tires on a Z. The small volume of air...or nitrogen...didn't seem to make a difference to me, and I refused to pay the upcharge the dealer demanded for the nitro fill and explained why. The grin on the salesman's face, like the cat that was about to pump the neighbor's canary, slowly disappeared when I explained it to him in detail and a showroom full of people stopped to listen. I have a feeling that they lost a good bit of "found money" that afternoon.
If nitrogen is saving folks topping their tires off, then that's a big deal. I'll keep a watch on mine to see how they fare. I'm happy I read the entire thread.

This should answer most of the questions about nitro in tires:
