Nitrogen in tires, where to fill up?
 

Hey guys,

i was coming home from washing my car today and my low tire pressure light came on. I checked the tires and the lowest one is sitting at around 30PSI which i imagine is causing the warning.

I'm from Southern ontario, where can i get Nitrogen from? I've called around to a bunch of gas stations and most people don't even know what i'm talking about. It would seem that the only place you can get it is the dealer. Does that make sense, to have a tire that can only be filled up at a place thats only open 9-5? What happens if i just add air?

Thanks,

I'm actually having the same problem, temps dropping and my warning light keeps going off. As far as Nitrogen goes your only bet would be the dealer. I think they charge a one time fee of 30$ or so for a lifetime fill up of Nitrogen anytime.

Considering air is something like 75% N2 using it in your tires is not a problem.

costco in the area? all costcos use nitrogen and nothing else. as stated, the air we breathe is 78% nitrogen. its not neccassary to keep nitrogen in them. in "theory", nitrogen has many benefits but none of them work consistently on all vehicles. In my opinion, its over analyzed sometimes but whatever.

So i can add air, i do not have to remove all the nitrogen prior to doing so?

Yes nothing will happen. Your only adding 3PSI, no big deal.

correct

Air is 78% nitrogen. Besides the fact it's a scam. There are no benefits to a road car.

just filled up with air all at 35 PSI light still on, reset tire maintenance, light still on, WTF?

Nitrogen is not a scam. First year chemistry students can tell you that. Pure nitrogen does not fluctuate as much in presure compared to straight "air". It also doesn't contain the moisture of air, thereby reducing the chance for corrosion of the TPMS, etc.
I have personally tested the differences in pressure fluctuation and it is actually quite drastic.
Pure nitrogen also leaks much slower than air. Saying that air is 78% nitrogen is a bogus argument. It's 22% other components. It's those components that are the problem. That's like saying water is part Oxygen, so go ahead and breathe it.

dont worry it will go off within about 10 miles or so i believe, i remember getting a warning a while back and filled the tires back up to spec and took a while for the warning to go away...as far as that tire maintenance you are mentioning that is just a reminder for rotating your tires which is kinda silly cause its not really needed on our Z's

:owned:

i agree, its not a scam bh any means but its nothing people should be charging for.there are people who refuse to out anything but nitrogen and its a little extreme. if yiu have access to it, then yes, its worth putting in over normal compressed air but nothing to worry about paying for IMO. Most of its benefits like the pressure fluctuation isnt a big deal if you just check your pressure once a month like recommended....

I think its still a scam even though the theory is sound. Taking this measure is totally unnecessary for the average driver yet, dealerships hype it up like they are doing you some huge favor.

Paranoia alert:
I actually don't think they even fill them up with nitrogen in the first place. I think a lot of dealerships just put those little green caps on the valve stems and call it a day. At the very least, I can almost guarantee that when they check tire pressure and fill as necessary, they use an air compressor and not nitrogen.

Um... No, it's NOT a scam:shakes head:
:iagree:Thanks for the more correct info.


Honestly, the big issue with the argument of air is 78% nitrogen is BS, the biggest thing with PSI fluctuation is probably the water inside the compressed air...
Have you ever noticed water coming out when taking air out of your tires?


You COULD fill with a pump that has a drier (The chemical lab I work for has driers in the lines and after the compressor to remove water, and holy crap there is a LOT of water)



My advice, if there is a Costco near you, become chummy with the tire guys, they use nitrogen, either they'll top you off with Nitrogen for free or they might deflate all your tires on the rack and refill them with Nitrogen for free :tup::tiphat:
