Some off roaders carry bottles of CO2 to air up there tires; so simply carry the same size bottle of dry nitrogen, available at any welding supply place.

Some guys do carry nitrogen, but the big difference is capacity. CO2 in a bottle is liquid and offers a lot more fills than nitrogen gas in the same size bottle.

just put a very small pin hole in your tank than the oxygen will leak out leaving the nitrogen behind where would you put the hole on the top or bottom

Found this and it gives a very good overview. Know that some will never use it but more information is a good thing:

Nitrogen Information
We know that you will benefit by using Nitrogen in your tires instead of air. There is a lot of advantages that you should be aware of, and with that in mind we offer this information.


What is Nitrogen?

Nitrogen is a dry, inert gas used to inflate airplane tires, off-road truck tires, military vehicle tires, and race car tires for improved performance, more tire mileage and better fuel economy.

Why use Nitrogen?

•Less inflation pressure loss
•Reduced wheel corrosion
•Prevents inner-liner rubber deterioration by oxidation
•Tires run cooler
•Increases tread life
•Increases fuel mileage
•Helps prevent uneven wear

Oxygen in compressed air permeates through the wall of the tire, thus reducing the tire's inflation pressure. During it's journey through the tire wall, oxygen oxidizes the rubber compounds in the tire, causing under-inflation and deterioration of the rubber . Dry nitrogen will maintain proper inflation pressure and will prevent auto-ignition, will not corrode rims, extends valve core life, and will help the tire to run cooler.

The biggest advantages - improved tire life

Experts in the tire industry indicate that oxidative aging is one of the primary causes of decreased tire life. Oxidative aging is caused by the diffusion of oxygen from the pressurized air cavity of the tire to the outside atmosphere. Tests have shown that if tires are inflated with nitrogen, there is a significant reduction in tire failure.



Why did race cars, military and off-road vehicles switch to Nitrogen?

Air is about 1/5 Oxygen, and oxygen, especially at high pressures and temperatures, is a very reactive element.
When oxygen reacts with things, the process is called oxidation. When oxidation is extremely rapid, it's called "burning.
That's one reason nitrogen is used in off-highway and aircraft tires. These tires run so hot they can actually catch on fire. Nitrogen doesn't support combustion, so nitrogen-filled tires don't add fuel to the flames. And nitrogen helps prevent slower forms of oxidation also.

Nitrogen prevents other types of corrosion as well


Oxygen and moisture corrodes aluminum and steel wheels. Oxygen also reacts with rubber, another type of "corrosion". When this corrosion starts, the small particles break off and form rust and dust, which can clog vavle cores, causing them to leak. The rough surfaces created from the corrosive action on the wheels leads to tire beads that don't seal properly, causing additional leaks .
Oxygen also ages the inner liner, the thin layer of rubber inside the tire whose function is to keep air away from the carcass. As the inner liner ages, more and more air molecules can pass through it, causing more pressure losses. These pressure losses in a truck tire can average 2 psi a month as a result of the air passing through the sidewalls. As it passes through the rubber, the oxygen can also corrode the steel cords, causing them to rust too.


How does Nitrogen help?

While both nitrogen and oxygen can permeate rubber, nitrogen does it much more slowly. It might take 6 months to lose 2 psi with nitrogen, compared to just a month with air. And nitrogen is far less reactive. It doesn't cause rust or corrosion on steel or aluminum, and it doesn't degrade rubber. Wheel surfaces stay smooth and clean, rubber remains supple and resilient.





Nitrogen also will not degrade the rubber seal in the valve core which extends valve core life and helps prevents core leaks.

Small bits of dust and debris as a byproduct of oxidative corrosion to the wheels and alloy rims can lodge in the valve core seat, causing air leaks.





Any other reasons for using Nitrogen?

Water!! The air around us is full of water vapor. Compressing air concentrates the water in it.


Draining the water from your compressor tank daily helps, but unless you have a really efficient air dryer system, chances are that there's a lot of water in your compressed air.
When you compress air, it takes up much less volume, but the percentage of water by
volume is greatly increased.



...and what harm does this moisture cause?


Water vapor in compressed air acts as a catalyst, accelerating rust and corrosion. Water vapor also absorbs and holds heat. And when it changes from liquid to vapor, water expands tremendously in volume.
As a result, tires inflated with wet air tend to run hotter and fluctuate in pressure more. That's one of the reasons why racing tires, where fractions of a psi can radically change the handling characteristics, are inflated with dry nitrogen.
Will my tires have 100% Nitrogen after they are filled?

In reality, no. The Ingersoll-Rand Nitrogen Generator puts out 98% pure Nitrogen. On an uninflated tire, there is still some air present, so after you refill with nitrogen, you'll end up with about 95% nitrogen, which is enough to do the job. That can be increased slightly by filling up the tire with nitrogen without a valve core in the valve stem, and then letting the tire delate. Then install the valve core and refill to normal pressure with the nitrogen. (purging)



For fleets - reduced operating costs

Tires are one of the primary costs of operating a fleet of vehicles. Tire costs include procurement, maintenance and the cost of blowouts.
A typical truck tire with two retreads costs $480.00 and lasts
approximately 270,000 miles. Inflating tires with nitrogen will help to prevent premature casing failure and allow tires to be retread
multiple times, with confidence and reliability.

Inflating tires with nitrogen to eliminate oxidative aging can extend tire life by up to 25%.

Increasing tire life to 337,500 miles would save $120 per tire.

A fleet with 50 trucks and 900 wheel positions would save over $100,000 in tire cost by inflating with nitrogen.

The primary cost of maintaining tires is the cost of labor to check tire
pressures and top off tires with compressed air on a periodic basis.
Tire pressure must be checked and the tires topped off due to the
diffusion of air through the tire. Tires filled with nitrogen will not
experience this diffusion and resulting loss of pressure. Tires
filled with nitrogen maintain pressure for a much longer period
of time than tires filled with air. If a truck fleet conducts preventative
maintenance on 5 trucks per day and presently spends 30 minutes
per truck topping off tires, they could realize savings of $31,250
per year based on a labor rate of $50 per hour and 250 work days
per year, by inflating tires with nitrogen.


A recent article from the Wall Street Journal states:

“One thing government and tire-industry officials agree on is the
importance of keeping tires properly inflated. The risks of
underinflation, which stresses tires by causing their sidewalls to flex more and the air temperature inside to rise, were highlighted during congressional hearings two years ago into the Firestone tire problems. Underinflation was identified as a factor in the failure of Firestone tires.”

Wall Street Journal, September 25, 2002.




Frequently asked questions.

Is Nitrogen explosive?
No, in fact, nitrogen is very inert and safe. Nitrogen is the most commonly used chemical in the USA. It is used for storing and packaging of snack foods, coffee, and other food items.


Will Nitrogen affect the tire pressure monitoring system on my vehicle?
Yes. Nitrogen will help maintain proper inflation in your tires and reduce the number of faults detected by the TPMS.

Do I still need to check tire pressure?
Yes. But, you will find the tire pressure to be much more consistent.

What about my spare tire?
You should certainly inflate your spare with nitrogen to help maintain proper inflation when it comes time you need to use it. Because of the slower air pressure loss of nitrogen through the sidewalls, your spare is more likely to be at proper pressure over a long time than if it was filled with regular air.

Will Nitrogen affect my ceramic Dyna Beads?
No, in fact, you couldn't find a better operating environment for this tire balancing product than a tire filled with nitrogen.

What do I do if I have to add air?
No problem at all. The small amount of air you may add at some point will still be a very small percentage of the total mixture of air/nitrogen in the tire.

Are you a Dealer, Fleet Owner, or Tire Shop interested in owning a Nitrogen Generator?
Need more information?

First, see a 2006-2007 study on the money you will save below:
Supplier News Parker posts results of nitrogen tire inflation trial
By CCJ Staff

Drexan Corp. recently conducted a double blind study measuring the effects of nitrogen tire inflation on tire life and fuel efficiency in a long-haul trucking fleet. Performance of nitrogen-filled tires was measured against performance of air-filled tires with and without a maintenance program.

Parker Hannifin, based in Haverhill, Mass., provided the nitrogen generator used during this study. The results of this analysis, according to Parker, recently were presented at the Clemson Tire Conference:


•When compared to historical data, nitrogen tire inflation provides a 6.1 percent improvement in fuel efficiency when compared to a fleet with no tire pressure maintenance program;


•When compared to historical data and an in-trial control, nitrogen tire inflation provides a 3.3 percent improvement in fuel efficiency when compared to a fleet using air inflation and a tire pressure maintenance program; and


•When compared to the in-trial air control, nitrogen-filled tires provided an average tread life improvement of 86 percent when compared to a fleet using air inflation and a tire pressure maintenance program.

The study, Parker says, infers that casing life improves, increasing retreadability, and tire failures decrease. The economic implications of nitrogen tire inflation also were impressive, according to the company:


•Saved 110,000 gallons of diesel and U.S. $285,000 over the nine-month period;


•The value of the extended tire life was not monetized, but could be calculated easily for any fleet that knows their cost/mile for tires; and


•Greenhouse gas emissions were reduced, allowing them to be exchanged for revenue on carbon trading sites.

Parker says the study was conducted over a nine-month period in 2006 using a fleet comprising 70 long-haul tractors and 117 trailers, providing 1988 wheel positions. It consisted of 6.1 million tractor miles and 110 million tread miles, and it covered the coldest and hottest months of the year to minimize climate variances, according to the company; the analysis isolated inflation gas as the primary basis for any change in the mean.




The easiest way to obtain Nitrogen:

1. For Motorcycle Dealers, Off Road shops or for personal use, we offer our tank-mounted system.


The advantage to this system is low cost (leasing usually $57 - $75 yearly) and higher purity (99.99%) than a Nitrogen Generator. This is a Nitrogen rated regulator and hose, available on the Products/Pricing page.




2. For Tire Dealers, Fleet Operators, Automobile and Truck Dealerships, we advise a self contained Nitrogen Filling Station.



Our sincere thanks to Bridgestone/Firestone and Parker Hannifin Corp.

wonder who we is in we offer our tank-mounted system I would like to see what the cost of different options for the farm and do my own tires it is important to have the same psi in the tires of all equipment every year the digger type equipment tires are way low and sounds like would definitely help in tire deterioration.

Just came back from the shop. And Bird, I also paid for a new set of Gorilla Glass glovebox bearings. Ok, that part wasn't true.

This is a great thread! :waytogo: There's nothing like the nitrogen vs. oxygen discussion to kill hours and hours on a completely useless topic :peace:

image.axd


Filling tires with nitrogen involves filling and purging several times in succession, serially diluting the concentration of oxygen in the tire. This will also remove any water.

It's certainly simple, although time-consuming, for a tire technician to fill and bleed tires. But most shops use a machine that not only generates almost pure nitrogen by straining the oxygen out of shop-compressed air, but will also automatically go through several purge cycles unattended. Some shops have been charging as much as $30 per tire for this service. I think that's too much. If you're buying a new tire, it should be far less. Still, the nitrogen generator, filling system and technician's time aren't free—the dealer is entitled to some return for that.

So, to answer your specific questions: With nitrogen, your tire pressures will remain more constant, saving you a small amount in fuel and tire-maintenance costs. There will be less moisture inside your tires, meaning less corrosion on your wheels. You will not be able to feel any difference in the ride or handling or braking, unless your tire pressures were seriously out of spec and changing to nitrogen brought them back to the proper numbers.

Nitrogen%20Man%20Logo%20-%20Receipt_full.jpg

Consumer Reports wanted to find out if nitrogen is worth the price, so we purchased a Nitrogen Inflation System and checked out how well the inflation held up over a one year period. We evaluated pairs of 31 tire models of H- and V-speed rated, all-season tires used in our tread wear test from 2006. We filled one tire per model with air and the other with nitrogen. The test was quite simple: fill and set the inflation pressure at room temperature to 30 psi (pounds per square inch); set the tire outdoors for one year; and then recheck the inflation pressure at room temperature after a one year period.

The tires were filled and deflated three times with nitrogen to purge the air out of the tire cavity. We also used an oxygen analyzer to be sure we had 95-percent nitrogen purity in the tire--the claimed purity limit of our nitrogen system, which generates nitrogen gas from ambient air.

The test started on September 20, 2006 and the final measurements were taken on September 20, 2007. The results show nitrogen does reduce pressure loss over time, but the reduction is only a 1.3 psi difference from air-filled tires. The average loss of air-filled tires was just 3.5 psi from the initial 30 pressure setting. Nitrogen-filled tires lost an average of 2.2 psi from the initial 30 psi setting. More important, all tires lost air pressure regardless of the inflation medium, so consumers should check their tires' air pressure routinely. No evaluation was done to assess the aging claim

Bottom line: Overall, consumers can use nitrogen and might enjoy the slight improvement in air retention provided, but it's not a substitute for regular inflation checks..



Tires - Nitrogen air loss study

---------- Post added at 04:42 PM ---------- Previous post was at 04:40 PM ----------

Another claim I've seen is that since nitrogen is slightly lighter than air, you'll save weight and get better performance. However, we're talking about a weight difference of less than 4 percent of the gas in the tire - in other words, a difference of less than an ounce for most vehicles. A possibly more realistic benefit is that nitrogen is largely inert chemically at low (i.e., normal) temperatures, so it won't attack the rubber in your tires like oxygen does. Oxygen attack is something both the National Highway Traffic Safety Administration and Ford Research have studied, and can be a problem for tires used for a long time or in rough conditions.

More important, nitrogen doesn't support combustion, which is one reason aircraft and the space shuttle use nitrogen in their tires. The wisdom of this precaution was brought home by the crash of Mexicana Airlines flight 940 on March 31, 1986. Shortly after the Boeing 727 took off from Mexico City en route to Puerto Vallarta, an overheated landing-gear brake caused a tire improperly filled with air instead of nitrogen to overheat as well and explode, rupturing fuel and hydraulic lines. The ensuing fire and crash killed 167 passengers and crew. However, unless your driving habits are of the X-treme variety, the chances of your tires catching fire anytime soon are slim.

Overall, filling up with nitrogen won't hurt and may provide some minimal benefit. Is it worth it? If you go to some place like Costco that does it for free with new tires, sure, why not? Elsewhere, though, I've seen prices quoted as high as $10 per tire, which is way more than I'd pay. Rather than shell out for nitrogen, you'd be better off just checking and adjusting your tire pressure regularly, something the NHTSA says less than 60 percent of U.S. motorists actually do.

The Straight Dope: Is it better to fill your tires with nitrogen instead of air?
