Nitrogen in tires

[projctWraith]

So is there any real advantage or hindrance from using nitrogen to inflate tires on a daily driven car?

compressed air is free at almost every gas station?

I believe he is inquiring because nitrogen is not affected by heat as much.

It would cost more, but it's an inert gas, hell, like 70% of the atmosphere is N.

Nitrogen is, as stated before not affected by heat as much. Nor will it permeate through the tire as fast. It contains no moisture so the internal wheel surfaces will not corrode. As far as I know, it is used to inflate all aircraft tires. At least all the Army aircraft.

Argueably 78-79% of our atmosphere is Nitrogen.

Remember leet, affected is not effected. Sorry man, couldn't help myself.

Holy hell, I'm an ass, sorry Mike. I don't know what the hell got into me last night, other than the "hiccup" alcohol.

On a daily driven car with street tires I see no advantage to using nitrogen. You have to buy it and you can't get it at every gas station. The advantage is on the track using race tires on a race car when tire pressures are critical to performance.

I heard it has some thing to do with expantion and you dont have to fill up your tires as much as you do with air

Usage Note: Affect and effect have no senses in common. As a verb affect is most commonly used in the sense of “to influence” (how smoking affects health). Effect means “to bring about or execute”: layoffs designed to effect savings. Thus the sentence These measures may affect savings could imply that the measures may reduce savings that have already been realized, whereas These measures may effect savings implies that the measures will cause new savings to come about.

Main Entry: 2af·fect
Pronunciation: &-'fekt, a-
Function: transitive verb
: to produce an effect upon; especially : to produce a material influence upon or alteration in "paralysis affected his limbs"

How much would it cost to fill up a tire with nitrogen?

Well I was asking because I actually use it at work and the cylinders usually get rotated before they are completely emptied. As it was stated that military aircraft use nitrogen in their tires; thats exactly what I use it for at work(check my profile). None of our technical manuals mention anything about compression characteristics of pure nitrogen. So I decided to try it out. I filled up my tires with nitrogen today and drove to lunch and later drove home. Somethings diffrent but I'm not sure what. As our atmosphere is roughly 21% oxygen and 1% other gasses. I suspect that the compression characteristics of pure nitrogen are more consistant than regular atmosphere. I believe nitrogen is what is used in our strut assemblies also; thus reducing another variable. Can anyone find anything on compression characteristics of nitrogen?

The deal with filling tires with Nitrogen is mostly that there's no moisture in the "dry nitrogen" that's used. As tires heat up, the moisture in them expands and causes a slight pressure increase in the tire. Would most of us ever notice? No. Unless you're a pro (or you can get the dry nitrogen for free) I'd say go with compressed air.

Ya, I had a bit to drink too, don't worry about it

Like mentioned above, nitrogen is dry..so there's no moisture, which can cause corrosion. The tire loses pressure a lot slower than air too, since the molecules are larger. It also disperses heat more quickly than compressed air, resulting in cooler running tires..so they last longer.

I don't know if places like Big Brand Tires charge to fill the tires with Nitrogen as opposed to air, though.

It's all in your mind. You won't feel any difference between nitrogen & air.

If you buy your tires from Costco they will fill your tires with Nitrogen for free.
