Here's what i am thinking.
You fill up your tires with nitrogen for FREE NOW. Next time you need to refill your tires, you got 2 options:
1) Go back to Costco to refill with nitrogen and most probably, they will charge you by that time.
2) You go to a local gas station, fill in regular air, most probably you mess up your tires (tires blowing etc...), some of you go to Costo to purchase new set of tires.
Either case, Costco wins in the long run, RIGHT ? |

Nope. Neither scenario. As long as you have a Costco card, you can fill for free with Nitrogen at any participating Costco for any time in the unforeseeable future.
And, no, mixing air with the Nitrogen (if needed) will do absolutely nothing to your tires if you're withing a few psi either way.
But, yes, Costco wins regardless of what you do. Costco is that da*n good!!!!!  |

Race tires are not perfect from the factory, we need to eliminate as many variables as possible.
Dunno why Costco would advertise Nitrogen, it's not free or cheap.

Well, there are several problems with what you're saying. Any gas expands as it heats, some less than others. Nitrogen is not completely inert either, it can tend to attract heavy metals (and who knows what is found in your set of belted radials). I suppose for the purposes of sitting in your tires, it is 'inert.' Any pure gas contains no moisture (read: water). As someone else pointed out, air is already mostly nitrogen and I highly doubt that Costco is giving you pure N2, which is very expensive for just filling tires. And once you have N2 in your tires, what happens when you try to fill them at the gas station? Therefore, I can't see any realy redeeming value in putting N2 into your tires. I certainly wouldn't pay anything for it.
The redeeming value, if you had bothered to look it up on google is lower temps, air pressure consistency, better mileage, and longer tire wear. This is nothing new, it has been proven over decades. Many big rigs use Nitrogen in their tires you bunch of idiots! |

Uhhh, filling your tires with Nitrogen is actually very smart. Why? When you fill your tires with air, the current humidity (amount of water in the air) goes into the tire. This means your tire pressure will fluctuate a lot more than you want it to depending on the weather. Nitrogen reduces the variation in tire pressure, increasing tire life and keeping your miles per gallon high. |

I wouldn't bother with the hassle. At the speed we're driving, it's not THAT critical if pressure fluctuated while driving.
It's different in racing because they are running at much higher speeds and that every fraction of a second counts. |

I think we covered this before. If they're giving 100% unadulterated N2 gas, this is true. But chances are they're not. Any good gas station should be giving you 'air' with very low humidity to avoid precisely the problems you describe. Again, there's not much difference between 89% N2 and 99%, as long as most of that other 11% or 1% is O2 and CO2 and not H20. |

Alternative gases for tire inflation:
CH4 - Methane - You can tell your tire is leaking because of the cow toot smell
H2S - Hydrogen Sulfide - How do you want your eggs? Sunny side up, scrambled, or ROTTEN!
O2 - Oxygen - Get stoned legally.
C3H8 - Propane - "Burn"-outs are the real thing!
H2 - Hydrogen - "Oh, the humanity!!!"
Ne - Neon - With clear tires and high voltage, they glow!
CO2 - Carbon Dioxide - Help the environment by containing green-house gases.
CCl2F2 - Freon - Even if your tires are bald, cupped, and falling apart, they are still "cool".

xcdhridr said:i want helium.
don't laugh. Most of my tires have a good amount of helium or argon in them! I do a lot of deep SCUBA diving (200+ feet) and use trimix (helium, ozygen, and nitrogen) for the breathing mixture. When my tires need to be topped off, I'll just grab whatever scuba bottle is handy and fill them, usually trimix or argon. I'd just as soon use normal air, but since I rarely dive using air, I just use whatever is left over. Next time I get a tank of nitrogen for cleaning my bottles, I might just use anything left over for my tires...just for kicks and giggles. <G> |

Only Ford Pintos with Firestone tires are allowed to fill up with Hydrogen. |

Apparently you've never had a blowout. You know those people you see on the side of the freeway? It's usually because their tire is flat, and it's usually because the heat of driving (or ambient heat on hot days) expanded the moisture inside the tires, causing it to burst. |

We were actually talking about coffins, hence the bad joke about dying. |

You have got to be kidding. Basic science: the "heat" of any tire at highway speeds cannot blow a tire! Look at a steam table. From 5 deg C to 60 deg C at 100% rel humid only causes a Max of 8% increase in presure.
Even over-inflating by 20% cannot blow a modern tire. |

Nitrogen is used to inflate aircraft tires as well. If you have hot brakes, and then of course hot tires, you don't want a big explosion. And, yes the heat of an underinflated tire sure can cause a tire to fail. You can easily get tread separation and have a blow out. You can generate enough heat to cause a bead deformation at the rim too. |

where do you go in the costco to get this done? the customer service part or the tire installation place outside? |

It is not true that N2 does not expand or expands less than air.
