Nitrogen filled tires

Out here (and I think Canada wide) tires filled with Nitrogen are re-capped with a green valve stem cap. But then again, there's nothing stopping someone from putting on a green cap, or vice versa.

My winter tires are filled with nitrogen (it was included with the cost, so I'm not complaining), and they explained that it expands and contracts less than regular air, which is good for -40 degrees celcius.

I don't know how accurate the info is, but who am I to doubt their judgement

 

If your water was 78% pure would you drink it?
For all of you obsessed with the 78%, that is still very different from 100%

The pros and cons of nitrogen tires are out there, but honestly, 22% is a statistically significant number

 

Important question here...

WTF does migitate mean!?!?

 

In Ben's defense, I have been to Beech Creek and the air did seem a bit low in Nitrogen.

 

Have you seen the water in PA?

 

i wouldn't say "migrate" I'd say the air seeps through the tires over time

 

Race teams also use nitrogen that has been processed by a filter (because that's all nitrogen is, filtered air) that can be sufficiently dried. My dealership has a small nitrogen "machine" (we call it) that does the same thing, in smaller quantities. However, I don't believe that our little nitro machine can't appropriately dry the air. Some of my coworkers swear by it, but when I did it to my truck, my tire pressures changed even more dramatically with changing temperatures. So, I did my little test three times over the course of two years. Very similar results each time, the second attempt being the one that kept the tire pressures closest to what I set them.

You will never ever get 100% nitrogen in your tires unless they are manufactured, shipped and then installed on your rims in a 100% nitrogen environment. When nitrogen is put in your tires, the air in them is vented into the atmosphere and then they are filled with nitro. Rinse and repeat that procedure, and you get to ~95% (+/- 1%) which is sufficient to reduce changing tire pressures to a nearly insignificant amount, maybe 1 psi every couple months and instead of 1 psi per 10 degrees F change, it is more approximate to 1psi per 30 degrees. And I believe that most places that offer nitro filling in your tires have a tester that measures the amount of nitrogen in the tires. We use ours periodically to make sure the machine we have is still working properly, or those customers who want proof we did it.

IF you can get nitrogen that is dried properly (usually available from a welding supplier, I hear) then it's worth every penny to set your pressures and run your tires off your truck. But I know that I won't be investing money into it.

EDIT: Sorry, that was really long winded, but I felt that it was pertinent information.

 

hahaha yes nitrogen is inert, we use it to flush out explosive gases in the industrial boilers at work.

 

I like my air like my women.....dirty and wet.

 

Nitrogen is not inert. There are plenty of compounds that contain elemental nitrogen. In fact there is an entire class of compounds called nitrates.

That being said, the compound found in air, N2, is relatively stable.

 

Parker nitrogen separator wand. Hooks up to any air compressor.

From Wikipedia, the free encyclopedia

Nitrogen ( /ˈnaɪtrɵdʒɪn/ NYE-tro-jin) is a chemical element that has the symbol N, atomic number of 7 and atomic mass 14.00674 u. Elemental nitrogen is a colorless, odorless, tasteless and mostly inertdiatomic gas at standard conditions, constituting 78.08% by volume of Earth's atmosphere.

 

Seems like everything is going up nowadays.

 

I think where the confusion is between nitrogen (the element) a nitrogen (the compound, N2).

N2 is not an element, it is a compound, consisting of two nitrogen molecules with a very strong bond, which makes it diffulcult (but not impoossible) for it react with other compounds (hence the "mostly inert" comment above).

Nitrogen, the element, is not inert. It is common in nitrates, which are compounds that contain NO3-.



Also from wikipedia, the only truly inert gasses are listed below. These gasses have no free electrons, so they by definition cannot bond with other elements, which makes them inert.

78.08%

xD

 

x2 on that one, its still early here. Let me have my sleepy logic

 

I think you have your atoms, compounds and molecules confused.

Someone else said, but unless you have TWO valves on your wheel, you can only add nitrogen to the mix that's already in there when the tire was put on the wheel. Unless the tire was put on the wheel in pure nitrogen environment...

 

From my understanding, the best reason to use nitrogen in tires is that there is no moisture in the tire when it has nitrogen in it. I have a buddy that is an airplane mechanic and they will only use nitrogen in their airplane tires as he says they never have a problem with any kind of moisture/corrosion on the inside of the wheel. He did say that all the mechanics use nitrogen in their personal vehicles and they say this: the ride is a little stiffer, they haven't noticed a significant increase in MPG, and they say it's not a great idea to mix air with nitrogen as this will defeat the purpose of running nitrogen in the first place. Most of them have switched back to plain old air. I guess the jury's still out on running nitrogen on passenger/truck tires but there are applications where the benefits would be worth it. Just my .02
