The owner of this car for sale says that the car has 17" alloys with new tyres filled with nitrogen.
I was just wondering, do people actually do this, and why? |

Yeah people do it. Its suppose to be better than air because Nitrogen molecules are bigger, so you don't lose pressure as quickly.
The thing is that air is 70-80% nitrogen, so the benefits of paying (i think $70) to get a slightly higher nitrogen content cant be that great.
That being said, I've never done it so I can't tell you if there is actually much difference. |

Hi Dean,
nitrogen is a denser compound than air, so when the tires are stressed (turning corners)the air compresses, making the tyre compress and bend, which increases the ware on your tires. Because nitrogen is denser, the tyres dont bend thus reducing the normal wear and tear of the tyre. Go to bob jane on Nepean highway in Moorabbin. ask for Steve and tell him Dewtch reccomended you. you only pay for the nitrogen once, top ups are free  i have it done on my car |

also, i think, with normal compressed air it changes pressure due to different temperatures, i don't think nitrogen does, it stays at a certain pressure. but, im no scientist, so im not quite sure on this one. |

This is mostly voodoo.
Firstly, Nitrogen molecules are not bigger than Oxygen molecules, they are smaller, with lower density and lower viscosity. That is, Nitrogen will theoretically (but not noticeably in practical tyre use) leak faster. Whoops!
Secondly, Oxygen and Nitrogen lie next to each other on the periodic table and have densities within a few percent. If the difference in density were significant then the atmosphere (which is a mixture) would separate into Oxygen and Nitrogen layers, which it does not.
Thirdly, Oxygen and Nitrogen have nearly identical thermal properties. Compressibility or expansion of pure Nitrogen will be the same as air. This is related to the fact that Nitrogen makes up 78% of air already. Further, how pure do you think your "Nitrogen" in your tyres is? Unless your tyres were wholly evacuated of air then filled in a nitrogen chamber, you have only about a 90%-95% Nitrogen mix anyway; probably less.
There are two differences worth mention. The Nitrogen is dried. To the extent there might be gains from that (another debate) you would make directly equal gains by using dried air, which is cheap to achieve and requires no special manufacture (separation from air) transportation or storage (saving the planet etc).
More significantly, oxygen is a highly reactive element. Inside the tyre, Oxygen reacts with the rubber, slowly oxidising the internal layer, just like rust on iron. Funnily enough though, my tyres wear dramatically faster from the outside. How about yours?
Nitrogen is preferred in certain applications for its lack of flammability and the fact that it is readily available comparatively cheaply as a dried gas.
All of my air top-ups are free, including the first one. |

So, you wonder, why do firms like Bob Jane recommend nitrogen? I have not read their business plan but I can mention two facts and some marketing.
1. They sell you a product for more than they bought it. That is called profit.
2. You go back to them for refills.
3. They gain an aura of greater technical knowledge than some competitive tyre places. How many people read up on the chemistry and thermal properties of air and its components?
4. Having a minor relationship with them, you are therefore more likely to buy tyres there again. That is called profit too. |

Rubber is oxidised by ozone (O3), which is quite common in cities as a result of various types of pollution (foremost being the breakdown of hydrocarbons, like unburnt fuel and vapour loss from tanks). It's also broken down in the medium-long term by exposure to sunlight.
I guess this is why the insides of tyres last longer than the outsides |

David is 100% correct. I'm not sure who made up that claim about nitrogen not expanding with heat. It obeys the old PV=nRT gas law just like plain air does. R is a constant and in a tyre, n is fixed. So if T goes up, PV must as well. So either the pressure rises or the tyre expands. A little of both, and to the same degree as a mixture of gases as for N2. This snake oil needs to be outlawed by the ACCC. It is complete BS advertising.
Where this use of nitrogen has come from is that it is used in aircraft tyres, so people think it is "better". The reason it is used in aircraft tyres is that it is completely dry. Air is about 1% water vapour. Even the air that comes out of a standard compressed air dryer will have a little bit of water in it. That's too much in an aircraft tyre. They see temps well below freezing and many cycles to and from freezing. Little bit of water in there will gradually open up any cracks in the inner surface of the tyre as the ice expands.
Dried air is not good enough for aircraft. Instead they use N2 which is extracted from air in a process which necessarily eliminates ALL water.
I believe nitrogen molecules do have a larger effective diameter, and oxygen will oxidise the inside of tyres.. but both of these are silly reasons to use N2 anyway. Check your tyre pressures for the first one. The only way the second would come into play is if you wore the same tyres for 20 years without driving. In that case, the oxygen has been working on the OUTSIDE anyway.

I don't care about all the argument for Nitrogen or not, but when I had new tyres last year I was offered Nitrogen for just $10 more so I took it.
Notice no difference EXCEPT I haven't had the need to pump up my tyres in the past 12 months.
So for that alone it was worth it. |

ok.. so if I add nitrogen into my tyres, the only benefit that i can see is that the inside of my tyres will last longer.... ok, that might be good if i ever intend on letting my car sit for 30 years... but hang on. won't there be air on the outside, decaying it???
no reason to use it.. i own an air compressor.. if they charge you $70 to nitrogen fill your tyres, come and see me! i'll fill your tyres with my "compressed air" from MY "compressor" and i'll give it you at 10% their cost!! Bargin!! |

We use it because it doesn't fluctuate in pressure as temp changes. Great for race track conditions where you are constantly changing pressures due to track temps rising and falling.

Jan
Where do I even start. How about learning some science before you open yours?
Tyre temp has nothing to do with the gas inside. It is the amount of friction between that tyre and the road. This is routinely different between tyres, depending on its position on the car. This is why race cars run staggered pressures. If you like I can explain this further. The heat capacity of the rubber is so much greater than the gas inside that any effect that the gas could possibly be having is negligible.
People.
Go learn some physics.
Seriously.
THERE IS NO POSSIBLE WAY YOU CAN CHANGE A GAS'S TEMPERATURE WITHOUT CHANGING ITS PRESSURE, IF THE AMOUNT OF GAS IS KEPT CONSTANT, AND THE VOLUME IT IS CONTAINED IN VARIES SO LITTLE AS IT DOES WITH A CAR TYRE.
Use normal, dry, shop air. |

I had it in mine for about a week. After skating around bends at 30km/hr I decided to remove it again. Never had the problem again.
I think on afterthought that it was probably because the tyres were new and not scrubbed in but it happened after a 300km drive. Go figure.
I personally think it's a bit of a wank. As Dave and Miles said, pure profit.
If indeed it makes your tyres run colder then that is another reason for me NOT to put it in. |

With regards to the water content.
Mass of air in an average low profile tyre will be about 12 grams by my calculation. 1% of 12g is about 0.12mL of water. That's about 1 raindrop.
Now my compressor has a decent dryer on it, and the air that comes out the end is good enough to paint with. So let's say 90% of the water is gone (I'd say it's much higher than that, but anyway). Each time I use my compressor, I drain the tank of a few mL of water. I only ever need to drain the dryer every month. So we can assume that most of the 90% of the raindrop of water condenses against the side of the compressor. More still on the walls of the hose.
So even if you don't have a dryer on your compressor, you might get 20% of one rain drop in each tyre. And this is what people are scared of expanding so much?
Last time I checked, guys running street cars pretty hard at the track were seeing tyre temps around 160F or 70C. Let's say ambient is 20C.
Vol @ 20C = 0.024 mL
Vol @ 70C = 0.0245 mL
So we are talking about 0.0005 mL change in volume for the water skewing the hell out of our tyre pressures??
Please.
Now the gases that make up the air will perform like an ideal gas, just like the pure nitrogen. They will obey PV=nRT. The specific heat capacity of nitrogen is higher than that of oxygen, so it can absorb a little more kinetic energy before its temperature goes up. But by "a little", I am talking about maybe one or two joules?? This is far outweighed by the heat capacity of the rubber tyre, the steel belts in it, and the metal rim.
If you'd like to feel one or two joules.. well, you can't. It's probably about the amount of heat that a standard hard disc LED on the front of your PC puts out in 20 seconds. Wow.. burning. |

Now, if we look at water vs the ideal gas law.. water actually expands LESS with a rise in temperature than a gas.
So water is actually BETTER for this "no change in pressure with rise in temp" theory. |

If you are one of the 85% of Americans who
doesn't regularly check tire pressure,
you need nitrogen.
We take in nitrogen with every breath. Air is composed of:
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.
Because of their large size, nitrogen molecules are the least permeable and stay in your tire longer.
It's not about the nitrogen. It's about reducing oxygen, water vapor and other gases.
By reducing the percentage of oxygen, water vapor and other gases in your tires from 22% to 7% or lower, your tires will maintain proper pressure longer than if you use “plain old air.” For example, with 95% nitrogen in your tires, they retain optimal pressure three to four times longer. |

ok, so it lasts 4 times longer. what is the average cost to fill all 4 tyres with nitrogen?
lets say, $20 for all 4. filling with compressed air is free..
you get a flat from a puncture, costs money to fill it once its repaired with nitrogen.. filling with compressed air is once again free..
top ups. I'd imagine it would cost something to do the regular check and refill with nitrogen. compressed air is still free..
to add to this, if you don't check your tyres at least once every 2 or 3 months, you're either plain lazy, or asking for trouble.
I'll agree with miles. its just another gimmick.. compressed air is free... and i'm still adding my tyre with 78% nitrogen for nothing.... |

Claptrap.
The water vapour being negligible, this effectively asserts that all pressure loss is owing solely to oxygen loss. What nescient nonsense.
Facts: Nitrogen is not "thicker" than air or oxygen. It has a lower viscosity and lower density than Oxygen and a lower molar weight.

On the proposition that Oxygen escapes 3-4 times faster than Nitrogen, by refilling your tyres with mere air every time they drop a couple of psi from, say, 36 psi, you can achieve a 99% pure nitrogen content in roughly half a dozen air refills 
I think my tyres are manufacturing excess nitrogen right now. 
For those that do not get it immediately, the supposed excessive loss of oxygen produces a higher ratio of nitrogen to oxygen in the remaining volume & pressure. Adding air introduces 21% oxygen only in the 2psi added, having negligible effect on the already improved nitrogen proportion in the other 34psi. The added oxygen then dissipates rapidly by this magical theory, and the ratio of nitrogen to oxygen further improves. Then we do the cycle again.
I could model this accurately for you but why bother? |

It's silly of me you allways know best. But here are some arguments against you. I suppose they don't know what they are doing.
Who Else Is Using Nitrogen?
NASCAR - NASCAR teams use nitrogen because it allows them to more accurately predict tire pressure fluctuation. Nitrogen fluctuates with temperature change, but it does so less than when water vapor is present. In addition, higher nitrogen levels eliminate the explosive properties of oxygen (oxygen loses its explosive properties at around 9% or less) NASCAR uses bottled nitrogen for portability. The bottles are delivered to the track by Praxair.
Commercial Airlines – The Federal Aviation Administration requires nitrogen in aircraft tires because it reduces the potential for water vapor freezing at high altitudes. In addition, airlines such as Boeing use nitrogen membranes or “OBIGGS” on-board inert gas generation systems (OBIGGS) to layer fuel tanks with inert nitrogen. Again, this reduces the potential for explosions. Just imagine if the Pinto had incorporated this technology 30 years ago, we'd still be driving them. Maybe…?
U.S. Government – NASA and the U.S. military use nitrogen for many of the same reasons it used in commercial aircraft.
Food Processors and Packagers – Oxygen hastens both the chemical breakdown and microbial spoilage of many foods. Think meat, potato chips, cookies, etc. To help preserve foods longer, processors and packagers often use modified atmosphere packaging (MAP) and controlled atmosphere packaging (CAP) that replaces some or all of the oxygen in the air inside the package with nitrogen. |

Jan I think I have proved with numbers that liquid water in fact does not vary your pressure as much as any gas. So that argument is out. Also, if tyres were so permeable to water, why don't they fill up with it? And surely it would creep back in due to osmosis? No? Strange.
Unless you are repeatedly freezing your car or launching it into space, the next 2 are out.
And do you keep food inside your tyres?
Also I notice no response to my reply to your smart arsed comment. Still not sure how you figure a little extra nitrogen in your sealed tyre is going to magically cool it. But gee I guess I haven't done such a scientific test as filling two different tyres on different wheels on a car going round a race track, so maybe I should keep my mouth shut.

David's perfectly right too.
Fill tyres with air.
Wait. Oxygen is now gone and tyres are 78% full of pure nitrogen.
Fill tyres with air. Tyres are now 95% nitrogen.
Hey, why not just overfill them 1psi at the second time, and they will leak back down to pure nitrogen? And surely they would never leak again. |

Jan, you implicitly accept all the logic of my previous post in that you make no argument against it but instead raise irrelevant examples of cases where nitrogen is used other than in road car tyres.
Yes, Oxygen reacts strongly chemically. I said so previously, and so did Mike Triggs who has learned a thing or two about atmospheres in his time. So what?
Yes, NASCAR uses nitrogen. Better still, so do F1 cars, not to mention Rob Hayden  (see his post). An F1 car is exceptionally sensitive to pressure variations because pressure affects its take-up and release of heat, where the tyre has a very narrow optimal grip range. Nitrogen is readily available, dried and pure so a few potential variables are simply eliminated. This has the same relevance to road cars as does doing a ten lap "fuel burn" before driving to the supermarket for milk. Any infinitesimal theoretical impact is drowned in other variables.
For the packaging of potato chips and use by airlines, NASA the CIA and the president's poodle, Miles has more than answered.
The main point I attacked was the notion that oxygen leaks from the tyre 3 or 4 times faster than nitrogen and is thus almost entirely responsible for pressure loss. No, it does not and is not.
Edit: F1 tyres need to hold their pressure for a few minutes to an hour, not weeks or months. Pressure loss is basically uninteresting to them in terms of notable problems to solve. They are worried about heat management and car balance which are related to pressures selected for the tyres. The heat sink remains the rubber and metal interfaces to air, not the tyre contents. |

There are so many bullshit snakeoil products on the market.
This reminds me of when they outlawed lead content in petrol - every garage out there was flogging off magnetic fuel enhancers that suposedly reduced upper cylinder wear and improved gas efficiency by "aligning the molecules" of the petrol or some such crap. What it really was was a $200 piece of pipe that did nothing. |

Because Nitrogen leaks out of the hoses faster than oxygen, reducing the pressure and therefore power available at the tool head. Also, nitrogen absorbs all the heat keeping the tool much cooler for the user, which is an important industrial safety issue.
How is my plausibility rating?
