Nitrogen filled tires

[bgilbert]

What's the story on nitrogen filled tires? I can get unlimited nitrogen cylinders at work. Boss told me he's been filling his with it for the past few years. Says tire shops charge extra for this? Nascar uses it? Thought I'd throw it out here, too lazy to google it .

Airplanes use nitrogen in tires because of the altitude factor, I didn't know anyone used them in normal tires. I would assume it has something to do with heat, but thats just a guess.

It's supposed to leak out slower. Something else too, but I can't remember what.

we use nitro in alot of our tires, the main purpuse is the dont change with weather like air does, our low pro tires would go flat if they didnt have nitro just because of the pressure drop

dealer charges a one time charge of 40 bucks and you get free unlimeted refills, even if you change a tire, get a flat, ext ext

FYI ~ air is 70% (+/-) nitrogen.

[cummins king]

are you sure its that much i thought it was 30%

[cummins king]

sorry my bad Air is made up of 80% nitrogen and 18% oxigen, and the rest is made up of my tail pipe,

For normal purposes, paying for Nitrogen to be put in tires is a big joke.

There might be some slight advantages to use it in highly sensitive applications, but the advantages would be so little that they would have to be scientifically calculated, kind of like buying the water-heater that gives you a .06% savings in electricity.


If you can get Nitrogen for free, and can't find any better use for it, then go ahead and use it; but, if it is gonna cost money, then just use plain old FREE air and keep the money in your pocket.

i would happen to disagree, we have a benz with low pro and a van with low pro and if they dont have nirto in it in the winter they will go really low, to low to drive

The only thing it will cost me is a regulator. I have one on my oxygen cylinder but rather not switch them around when needed. I have an extra 25ft air hose and 25ft coiled air hose I could use. I have 5 Dodge trucks and I'm always checking/setting tire pressures. If I can come up with a cheap regulator I might try it.

Why bother? You can only drive 1 at a time!

The main reason you see race teams use nitrogen is because it does not expand with heat. You start with 32 PSI on a cold tire it will end up around 35 to 40 PSI after it warms up. Using nitrogen it doesn't climb on pressure.

[PToombs]

Yeah! That was the other reason! Thanks Philip!

Try buying some new tires now and again, and you wont have that problem, Bill. The junkyard isnt the best place to get 235/85-16 tires. Those little bars between the tread arent added traction- they mean the tire is worn out.

I laugh at a guy at work who swears he gained some fuel mileage with nitrogen in his tires. I told him I have 78% nitrogen in my tires. He asked how, and I told him plain air. He aint the brightest bulb in the chandolier.
