Nitrogen in tires

x2 this...but I'm not paying for it yet )

 

On road driven cars, there really isn't much of an advantage with nitrogen. The only area where I've seen specific gas mixes work in tires is in motor sport, especially those that require all teams to use the same tire. Depending on how you tweak the gas mix, the spring rate of the tire will change but you can use the same pressures to better manage and predict the contact patch size, sidewall deformation, scrub and other qualities in the tire.

Tire data...it be crazy, yo.

 

This link is not an accurate test. He's comparing surface temperature of a bottle to gas pressure inside it- metal and rubber transfer heat entirely different and therefor his assessment can't be valid.

Just because nitrogen and air expand similarly in a test cylinder when put in a freezer and then put in direct sunlight does not mean that they would expand similarly in a friction-heated rubber car tire.



As far is N2 molecules being larger than regular air molecules, how can that even be possible, as air is a more complex molecule?

 

sorry i meant mpg not mph

 

I gained 4 mpg by switching to nitrogen

 

If they're talking about the O2 molecule, then it is a completely irrelevant statement that makes no practical sense, obviously because you wouldn't be putting straight O2 into your tires as established earlier.

...And the medium DOES matter, the heat transfer to the nitrogen through rubber and through cast iron are entirely different, therefor the nitrogen would be at an entirely different temperature in one container than the other at the same outer surface temperature. Also the fact that he was heating the surface of the cylinder and when your tires heat up, the entire density of the rubber is heated, it would make a difference.

I think the science for the use of nitrogen is valid on a broad sense. I think his experiment is irrelevant and invalid. HOWEVER, am am inclined to also believe, on the contrary, that the whole damn thing is a scheme and a racket to charge you more to fill up your tires, but that's BESIDE the point!

 

ITS JUST A SALES GIMMICK.

Makes you feel special - "oh I got nitrogen in my tires"

Do you really think dealers are paying to have pure nitrogen tanks delivered weekly
just to fill tires with them????????

 

I guarantee you, that no one on this board will notice a difference, in the trucks. In industries where seconds/ one or two percent count (i.e. racing or any high performance application), sure there is a difference, but not anything worth it on these trucks.

 

There is no "air" molecule, air is a mixture of nitrogen, oxygen, and trace amounts of other gases...

 

no water

 

We use it at work...there is a special compressor for it. It's just a dryer form of air. It does what it's supposed to: keep the pressure consistent.


Old people love Nitrous, Nitro and Nitros BTW.

 

nitrogen is good in ur tires. they had a thing about it on the speed channel on truck tv and they said that it is way better than air because it holds a truer pressure and doesn't fluxuate which helps with wear on tires. and where air condensates in the tire, the nitrogen stays cool which keeps condensation out of the tire. and with the tire holding truer pressure it helps mpg a little cause we all know properly inflated tires are better on gas!!!

 

silly observation...but air has about 85% nitrogen in it to begin with. And if aluminium is porris and loses air, slowly, but it does, would'nt we be left with nitrogen in our tires anyways??? I'm guessing oxegin, hydrogen, and what what ever else is in air, is smaller then nitrogen, and passes threw the rims easier. I'm guessing that because if nitrogen was smaller, why would we want to spend 45 dollars to constinally fill our tires.?.?.?.

 

I put nitrous oxide in my tires and my quarter mile time is down to 13 flat...

 

Use a little common sense.. The letter 'G' is next to the letter 'H' on a keyboard.

 

If I fart near my compressor and fill my tires, will my truck run like crap?

 

Nitrogen is an 'inert' or 'non-reactive' gas.
So filling your tires with nitrogen should maintain a continuously reliable/steady pressure longer, & also aid in prevention of the deterioration of the interior of the tire.
Both of these may be a critical advantage to a NASCAR driver, but I have yet to see any advantage for 'normal' operation...

the 'Tweel' from Michelin is a very interesting concept.. perhaps even the future of things....
