nitrogen tire inflation

[Suede]

The local Costco is now offering nitrogen tire inflation.

Do I need this?

Since when is "air" not good enough?

Does everyone else already have nitrogen filled tires, and I'm the last to know?

I dont but I found this for you....Nitrogen Instead of Air
Most of the teams remove the air from the tires and replace it with nitrogen. Compressed nitrogen contains less moisture than compressed air. When the tire heats up, moisture in the tire vaporizes and expands, causing the pressure inside the tire to increase. Even small changes in tire pressure can noticeably affect the handling of the car. By using nitrogen instead of air, the teams have more control over how much the pressure will increase when the tires heat up.

i got a shop supply book and there was one by the tire machines and **** it's expensive, "big money maker" for who them, said three months between pressure checks

all the ferrari 360 challenge cars run nitrogen
it doesn't heat up and its lighter than air i think
he (the ferrari mech) told me its to prevent
expansion and blowing up tires lol...i run air. =]

Just remember that air is composed of 80% nitrogen. So is that extra 20% really worth it (if it is in fact pure)?

I'm not running N2 yet until I get a fresh set of tires...

They make a big diff in ride comfort AFAIK... since pressure change is only very slight even after long runs.

N2 loading here costs about US$2/tire will lifetime top-ups

hmm...something conspirical, I like.

You gotta be kidding right? Geez, it sounds like the time when you could buy NASGAS (103 Octane) at Unocal. Everybody was putting it into their cars and swearing that it created horsepower.

Truth was that it Didn't make a damned bit of difference unless your engine was built for it (high compression, serious advance) and for $3.43 a gallon (ten years ago!) it just didn't make sense.

Can you feel the difference with Nitrogen? I sincerely doubt it......

if it's good enough for them Nascar boys to put in their tars, its got to be good 'nuff for dem BMW's...right?
Seriously I don't think it would do much for street cars but would it help a wee bit for those of you who track your e-34's?
