Nitrogen for Tires [Merged]

[mey0r]

How could Nitrogen be larger than Oxygen when its atomic Weight and Number are lower? .

Yes its larger with respect to permeation. Your tires hold pressure better because nitrogen doesn't permeate as quickly through the rubber as compressed air.

O2 "permeates" approximately 3-4 times faster than does N2 through a typical rubber, as is used in tires, primarily because O2 has a slightly smaller effective molecular size than does N2.

Read the mechanics of the flexing of the tire walls.

I've been saying this unless you are racing in the tracks, walang kwenta itong nitrogen sa tires...

[woohoo]

+1! Pautot lang yan at pampayaman! Di ba air is already composed of 78% of Nitrogen na? :hammer:

Look at the claims on this site: http://www.getnitrogen.org/why/index.php :

First it says:

• 1% Water Vapor and Other Gases – Escapes up to 250 times faster than Nitrogen
• 21% Oxygen – Escapes 3-4 times faster than Nitrogen
• 78% Nitrogen – The largest molecule in
  air, dry, non-flammable.

It also says:

Oxygen reacts and damages inner tire liners and belt packages; nitrogen does not.

Yeah, right. But then, even if that's true, how much can oxygen eat out of your tires in a year's time? That's negligible. I'm sure the wear on the outside is always greater than the inner wear from HUNGRY OXYGEN MOLECULES at any give time. :hammer: (I'm speaking from experience)

The www.getnitrogen.org site would even LIE and distort science right in front of your face....

Sabi daw:

78% Nitrogen – The largest molecule in air.

Nitrogen (Atomic number 7) molecule is smaller than Oxygen, Argon and CO2 and H2O vapor.

That's FRAUD right there and then.


Dati, nung na-uso yung nitrogen filling. Nitrogen fillers sprouted like mushrooms (or Shawarma) in almost every neighborhood. And the dealers would charge 200 per tire. Nowadays, a lot of people wised-up and found no real advantage to doing this-- imagine having to shell out 100 bucks or more every time you tap up your tires.

A lot of the nitrogen fillers lowered their price drastically (some down to just P25) and many just stopped selling because of poor demand.

Now, there is even a seperate thread asking where one could find a nitrogen filler.

Ang ganda ng debate ninyo ha parang "May Dyos ba o wala?"

Kung ano ang gustong isaksak sa gulong yun na lang po.

Pwede nga hydrogen kung gusto ng may-ari ng kotse. O kaya tubig.

If Nitrogen works for you, stick with it. If it's air, then that's it.

[tidus1203]

The only advantage I see with nitrogen is its higher resistance to heat so mas matagal bago bumaba ang tire pressure. If given free I would take it, but to pay for it NAH! Regular air is fine, maskin maubos libre naman sa gas station...

if may nitro na gulong pede ba lagyan ng hangin? la ba side effects? thanks!

[woohoo]

if may nitro na gulong pede ba lagyan ng hangin? la ba side effects? thanks!

Wala, after all, (and I reiterate) air is 78% nitrogen.

[woohoo]

Haven't you noticed the prices of nitrogen refilling stations as stated here? The highest has been Php200/tire and the lowest (recent months) is Php25/tire. :shocked2:

We're only trying to convince other tsikoteers because we care. Now, if after we present our ideas/opinions/arguments, they still want to spend unnecessarily for nitrogen refilling, that's their call. <shrug>

At least we did something about it. http://akomismo.org comes to mind.

Like Edmund Burke said, "All that is necessary for the triumph of evil is that good men do nothing."

And, like welscua's signature says, "Sharing is caring."

:peace:

[woohoo]

I'm skeptical.

IANAC (I am not a chemist) But then, it has been stated that having a smaller ATOM doesn't necessarily mean having a smaller MOLECULE, the way oxygen and nitrogen molecules are formed.

http://74.125.155.132/search?q=cache...ient=firefox-a

says that:

It is often mistakenly assumed that "molecular size" correlates directly with "molecular weight". O2 does have a greater
molecular weight (32) than N2 (28), but O2 is actually smaller in size. Thus, O2 fits through the relatively tight passage
ways between polymer chains in the rubber more easily than does N2. The difference is size between O2 and N2 is
very small, only about 0.3 times 10 to the -10th meters (0.00000000003 meters)

Hmmm... that's 1 decimal place inconsistency with the info on http://www.bbc.co.uk/dna/h2g2/A791246 :

Van der Waal's radii

Measuring the length of the bonds is not enough to determine the effective length of a molecule. This length is equivalent to the distance between atomic nuclei. However, the nuclei are surrounded by electrons, which will act as a sort of bumper, by repelling the electron-bumpers from other molecules that come close. To obtain the effective length of a molecule one must therefore also add the corresponding Van der Waal's radius, which is the effective radius of those bumpers, to both ends of the line. The bumpers are not strictly rigid like snooker balls; they have some flexibility, like balloons. For this reason the length obtained is generally the upper length limit for those molecules, they can however be shorter by some ten or 50 pm. In some cases, for example if they are compressed in a solid material, the entire molecular geometry can deform; in that case the molecule can become significantly shorter.

Selected Van der Waal's radii

* H:120 pm
* CH3:200 pm
* N: 155 pm
* O: 152 pm
* S: 180 pm
* F: 147 pm
* Cl: 175 pm
* Br: 185 pm

155pm-152pm=3pm

(pm = picometer/s)

3 x 10^-1 = 0.3 meters = 3 decimeters
3 x 10^-2 = 0.03 meters = 3 centimeters
3 x 10^-3 = 0.003 meters = 3 millimeters
3 x 10^-6 = 0.000003 meters = 3 micrometers
3 x 10^-9 = 0.000000003 meters = 3 nanometers
0.3 x 10^-10 = 3 x 10^-11 = 0.00000000003 meters = 30 picometers (yes, 30 picometers, not 3picometers)

I wonder who's right...

What say you?
