I read this on one of the other forums I monitor. This sounds very sweet.

For those of us that went all 4 on the Eagle GS F1-D3, this sounds very sweet. I might just give it a shot.

=========
Just replaced 2 of my tires @ Costco and they handed me a flyer: "We take tire safety to the next level with... NITROGEN Tire Inflation"

Basicly, they will inflate your tires with dry Nitrogen!

More info on Nitrogen tire inflation

PLUS: at the bottom of the flyer, it stated "In fact, we'll inflate any Costco member's tire with NITROGEN, no matter where the tires were purchased"

Edited: They changed my valve caps from the old black one to the green (alien green stuff), has a N on it! Cool but it look weird on my alloy wheel with black tire! Take your valve caps off if you don't want to loose it!

What good does nitrogen do in a tire as opposed to plain ole air?

So what's unsafe about regular ole plain free air

Normal "free" air is 78% nitrogen. I guess it is that 21% oxygen we don't want.

I heard that Costco will fill any customers bonnet with bees if you bring it in

I can hear it now- "Dude, you wanna race, I got naws in my car. I've got the new setup that goes in the tires, look, here's the green cap that proves it!!"

I am thinking helium might be better, you can reduce your unsprung weight, must be good for .1 to .2 in the 1/4

You guys are harsh!

It will reduce corrosion of your alloy wheels. I bet somebody has a computer.....look it up.

The primary reason to go with pure nitrogen is that it does not experience the same level of pressure change when heated. As most are aware (and you can witness this on your D.I.C.'s), the static pressure in your tires elevate from the heat / friction generated while driving. And the harder you drive, the greater the pressure increase (up to a point). So you could argue that setting the optimum pressure with nitrogen and having it stay consistent could be viewed as a "safety enhancement". The whole deal with filling the tires w/ nitrogen (for cars and bikes, anyway) comes from the race track, where its properties are more fully appreciated.

this is true
I doubt that the average guy would notice any difference though

Well my friend who is the Assistant MGR. of Costco up here has no idea about this, he even call (2) California stores and (1) Washington store and they didn’t know anything!

According to Butler Tire Company here in Atlanta, nitrogen will prevent corrosion of alloy or steel wheels. It will also maintain a more stable air pressure (doesn't go up and down as much because of tempreture).

Personally, I think it's a gimmick, but if you can get it for free, go for it.

First caskets, now nitrogen in the tires. Costco is really going all out, huh!

CO Lightfoot

Uh, no. It is true that tire pressure increases as temperature increases. This is Gay-Lussac's Law. But, under the mild temp/press conditions in a tire, the effect is the same for ANY gas. N2, air, doesn't matter. Ask any chemistry teacher.

Possibly, I can see using DRY air in a car tire. One cubic meter of saturated HUMID air holds about 50 grams (same weight as 10 nickels) of water at 100 degrees F. I estimate a typical car tire has enough air to hold maybe 10 grams water. If that condenses and freezes in winter, might it be enough to make a cold tire out-of-balance?

But use nitrogen in a street tire? Sounds like a marketing ploy to me.

Dark-Knight

Just when you think you've heard everything...

wrustywrench

I have heard of this before,, wont do any harm,,,if its free , go for it,,,you can always add regular air,,,,,why not put halonatron in yor tires, then if your car or sumthin catches on fire, puncture a runflat and put it out,,,,and drive home after wards.....(I know, stop me before I hurt myself),,,,,,,

RCK1999

I bet SAM'S CLUBS will soon be offering free air-change for tires. Everyone needs to have the summer air changed to winter air so that it doesn't freeze!

Dan_the_C5_Man

My comments were based on real-world conversations w/ race tire representatives at race tracks across this country. But it's possible that they are "all wet", but you have to wonder why they would bother; I don't have any personal experience with monitoring the pressure change difference from Nitrogen vs. O2.
