Nitrogen in tires?

anyone do this or have an opinion of this

thinkin about doing this to my grandfathers 1969 Ranchero when I get it to that point. Maybe even the Rauder.

Some claim it works... others don't see any difference. Most likely it wouldn't hurt anything cept your wallet.

BS. Noticed that my Ford dealer had attached a flyer for nitorgen tire filling to my service ticket last time. I saved forty bucks by ignoreing it.

Normal air is about 78 percent Nitrogen, so you are almost there already. ;)

all the tires we put on the migs and what not all get filled with nitrogen. not sure why though

[larryo340]

It really does not make sense to use nitrogen when you have a 4X4 and air down on the beach. I have a friend that got new tires for his truck from Costco and they filled them with nitrogen. One trip to the beach bye bye nitrogen.:rolleyes:

It is worth it just to get the little green valve caps !! :rolleyes:

Actually, the advantage of nitrogen filled tires for the average driver who checks and maintains proper tire pressure is negligible. IMHO it is just not worth the price and fits more into a "Fad" category rather than any real functional benefit.

Now if you were a race driver doing 150 MPH plus where heat variations affect tire pressures by 1/2 pound or so and seriously impact vehicle handling, then it might be worth considering. How often will your grandfather be taking the Ranchero to the track and laying into those high speed turns ? ;)

Save your money.

I was thinkin about it more along the lines of keeping the tires from rotting out and such. I'm a stickler about tire pressure so i wouldn't dare do it to a DD but something that I want to keep in good running condition that doesn't see the road very often I could possibly see it being beneficial in the long run.

IMO nitrogen is much better than air. It is not effected by changes in temperature, is better for tires and improves the handling qualities of the tires. Costco has been using Nitrogen for a couple of years at no extra charge.:D

All the big jets use it for a reason.

I have had nitrogen in my tires for over a year and no drop in pressure:)

[offroadkarter]

why not use helium? Your car would be lighter then :D

[jim geary]

Tires seem to stay inflated longer.

[jabird56]

Have KDW2s on the MM nitrogen filled now for 2 years, have NOT had ANY drop in tire pressure in that time. Also, nitrogen filled tires run cooler and help keep the rubber from becoming brittle,...they last longer.

But..........what about simple seasonal changes in pressure (beyond 4-wheeling on the beach). You have to add air into the tire as the weather cools down and then you have to let it out again as the weather warms up. I do this every year so that I keep my tires at the right pressure year round. What good is it unless you have a home N2 system to air up in the fall and winter. I don't get it.

i happen to have nitrogen around but im prolly the only one lol

I have NEVER adjusted my air pressure. Air will "bleed" out over time. Nitrogen does not, tires stay even.

That's true the nitrogen is not affected by temperature change.

[Aren Jay]

So I guess it is the other 22% of gases, in normal air that bleeds out?

Mainly oxygen CO2 and whatever crap we have in our air.

I do wonder what the earth would be like if all the nitrogen in the air was actually Oxygen.

A happy Earth, until all the plants died.

Sorry, all gases follow thermodynamic laws. If the volume remains constant and temperature is reduced, pressure must reduce. That's the physics. So air in a tire will go up and down about a pound for each 10*F change. It may be less for pure nitrogen but it cannot stay the same.

pV = nRT where p is pressure, V is volume, n is number of moles of gas, R is the Universal gas constant, and T is the temperature. See http://en.wikipedia.org/wiki/Ideal_gas_law.
