Nitrogen in Tires?

[WhatsUpDOHC]

OK - You've seen the news and placards at car dealerships where Nitrogen is being touted as a fuel saver, decreasing tire temperature and minor solution to decreasing tire pressure loss.

Just wonder what the MM.net experts think about nitrogen in tires.

On my '04 Marquis, which I just purchased in May, I have the green valve caps which means there's nitrogen inside.

Car gets the same mileage as my '02 Marquis did with just plain ol' air in it.

Cant say it did sqaut for milage,but tires did seem to hold psi longer

Unless your are driving a mile above the earth, snake oil. Errr, snake air.

Will it make your Marauder float?

Afraid not. Nitrogen is what they put in aircraft tires to keep them from freezing in the upper atmosphere. (It's scientifical stuff, I can't explain it.) But they do not seem to help an airplane stay afloat when they hit the water, so I'm going to go with no, won't help a Marauder float. Unless we can get someone really really drunk and talk them into trying it.......:cool:

Here's what I said several years ago .... I still feel the same. Do a search on "nitrogen" and you will hit several threads going back to 2005.


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 regularly 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.

Save your money.

Others think that Nitrogen will not degrade/oxidize the tire's rubber compounds and would be a long term benefit. Here's what I said to that ..... assuming anyone can get a set of MM tires to last long enough to degrade. :rolleyes:


So what's the point of preserving the inside of the tire ... when the outside is exposed to the elements ?? :dunno: The major benefit of nitrogen is that it is less expansive under heat, therefore better able to regulate critical tire pressures during professional races. The benefit to regular folks is nil. :rolleyes:

This is why I use Hydrogen. Makes the car lighter...

Throw on a couple of those electric superchargers pointing toward the ground and you will have the first Maraudahovercraft.

Believe me, I searched for Nitrogen a couple of times but didn't get any hits.

I was sure that there must have been posts about this.

Thanks!

The biggest difference you'll see with Nitrogen in your tires is the price you'll pay to inflate them when installed after you have a flat.

[boatmangc]

I use nitrogen in my 3/4 ton Sprinter van.
1)holds pressure much longer
2) seems to not go flat nearly as fast when you get a nail in the tire, (larger molecules need more space to leak through, thus slower leakage through puncture).
I like it, 100 miles a day at full payload, every little bit helps.

Nitrogen it actually bad for your tires and will cause them to run hotter.

On every car the tire placard always states the recommended COLD tire pressure. Usually in the owners manual in will also state that if you check the pressure after driving and find it higher than than the spec NOT to bleed off pressure. Many owner's manuals and tire mfgs recommend to add X psi for extended high speed driving.

The reason for higher pressure for high speed driving is to keep the tires cooler. Much of the heat that damages a tire is caused by the internal friction of the tire carcass flexing as it rolls. More pressure means less flexing and a lower tire temp.

The engineers at the tire and auto companies are not stupid, (even if sometimes it seems like they are) they are aware of the laws of physics and how a gas reacts when heated. So they take that into account and the fact that the tire is supposed to be filled with ordinary air when they set that cold tire pressure spec.

The fact that the pressure increases as the temp rises is actually a very good thing. It actually works to keep the tire cooler. The tire heats up from flexing and its pressure rises, which reduces the flexing there by reducing further heat build up.

Then search for "blinker fluid".

Air is mostly nitrogen anyway, >75% I believe... Nitrogen from compressed bottles is usually dry (no moisture) and we use it to fill aircraft tires @ 200-300psi. A standard air compressor output usually contains quite a bit of moisture. For a car this is just fine... nitrogen is a gimmick.

Wouldn't hydrogen take a couple of hundred lbs off the MM? :D And when your tire pressure is low you refill with air?.... :eek: :run:

[whitey]

i heard from the factory that all dtr's tires were filled with mercury vapor/gas....thats why they're slower.....don't kill the messanger.:D

[B.C. Bake]

Nitrogen is just an inert gas and doesn't expand or contract when heated or cooled like oxygen, also doesn't freeze. It's what's in shock absorbers, NASCAR uses it because 3 or 4 psi at high speeds makes a difference. For a every day car, it's a gimmick to charge you IMOA.:rolleyes:
