about how big a tank do you need to purge/fill your tires?
That's CostCo's tire fitting department that uses Nitrogen (look for green valve caps on local cars - that's their 'trademark' for Nitrogen filled tires.
Leading evidence: 'Fill tires' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Fill including costco' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

"Race teams uses nitrogen because it expands in a more predictable manner (than air), so teams can better determine how tire pressure will increase during the race." Got it from the current C&D mag.
I used to work for an Indy Lights team (driver was Patrick Carpentier) and we used nitrogen for tire fill, as do all teams at that level because it doesn't hold water like air does.

Hmmm...how about a specialty nitrogen tire filling shop called Der Hinderberg?

It's actually the water that causes the tires to get hot (or at least hotter than if there's no water in the the gas used to fill the tires).

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

a neighboor of mine with a 2004 996 cab very similar to mine told me that he got nitrogen put into his tires. he claims it helped handling a great deal.
i never heard of nitrogen in the tires before. does it really help handling without any side effects? anybody else done it here?
Many places use nitrogen fill, including COSTCO. Auto racers use it because nitrogen does not expand/contract like air does, as it get hot from heavy/hard use on the race track.
Costco will tell you this, which seems a bit of a stretch. "Nitrogen is said to prolong tire and wheel life, improve gas mileage and keep tires inflated longer than those with compressed air."
Costco's claim is absolute fantasy for a street-driven car - even a car that is driven hard on the street. I used to work for an Indy Lights team (driver was Patrick Carpentier) and we used nitrogen for tire fill, as do all teams at that level because it doesn't hold water like air does. It's actually the water that causes the tires to get hot (or at least hotter than if there's no water in the the gas used to fill the tires). And it's the increase in temp that causes the pressure to increase, so the dual benefit of nitrogen in the tires is more consistent tire temperature and more consistent tire pressure. You would not realize either of these benefits to any great degree on a street-driven car.

I don't think they'll be selling you a canister to inflate your own tires at home!
Chris.
I think people have been putting nitrogen in their motorcycle tires for years. the stunt riders do it alot cause it will help them get the front tire in the air easier.
You can find out more about Nitogen for tires here
GET NITROGEN
Has a 'find by zip code' feature, and also a 'Nitrogen savings' calculator!
And here's a manufacturer website, that has another 'find by zipcode' feature, to locate dealers that can fill your tires with Nitrogen
PURIGEN98
Chris.
The only thing Nitrogen does over dry air is to lighten your wallet. If you want to do something worth while get a dryer for your compressor, just get rid of the moisture. The only reason racers use Nitrogen is because it's easier to carry a tank of N2 around than a compressor and a dryer. And by the way, it will kill you very quickly using nitrogen in a confined space. You really need that 20% of O2, 10% will get you a face full of dirt.
This Nitrogen thing is just a racket.
The air you breath is 78% nitrogen and the nitrogen you get at Costco or any other tire shop is 95% nitrogen. The filters on the
machines they use
can't produce anything purer.
I agree, we won't see the benefit of nitrogen with a road-car. "Race teams uses nitrogen because it expands in a more predictable manner (than air), so teams can better determine how tire pressure will increase during the race." Got it from the current C&D mag.
The coefficient of expansion of all gasses is about the same, extreme little difference. It all relates, again, to moisture content, not the kind of gas it is. You want dew points of -30 deg C or better. Air at this dew point is just as good or better than the "Nitrogen" they are selling. I don't think the dew point of the commercial offering is at the -30 level. It would be interesting to know what the dew point actually is in the tire store gas. I don't know if it would make any sense to ask what the dew point is, don't think they would know. They could be doing more harm than good if the Nitrogen was wet. Anyone know the specs of the gas they are selling?
Dry ------ Good
Wet ----- Bad
There seems to be a lot of magic attached to this. (Merchandising)
