i was at Canadian tire today visiting my buddy and i saw this huge sign for nitergon filling for your tires. it claimed that you would get better handling,tire life, and gas mileage. i know nitergion is lighter then air but would this really work? it sound kinda dangerous to me.
what do you guys think of this, is it good or bad.

The theory of nitrogen in tires is great. Nitrogen molecules are larger than oxygen molecules thefore will not leak as easily (most tires/rims will loose air over time). Also, oxygen corrodes aluminum and causes rust on the bead areas of steel rims and causes rubber to rot, nitrogen won't. Nitogen is also less suceptible to pressure change with temperature(great for racing).
Sound good so far? Well here's what you really need to know about nitrogen in tires. All of the above info is based on using pure or very nearly pure nitrogen. Yes, nitrogen tire inflation machines are starting to appear here and there. But say, for example, you get a small hole in your tire or have a leaky valve stem. You stop at the gas station to top up the tire with regular old air. Even the smallest amount of oxygen in the tire negates ALL of the benefits of using nitrogen. You also don't have the option of finding pure nitrogen at every service station.
There are the facts you, be the judge. Hope this helps.
it is what we use in the AH-64D Apache tires in the AMRY
oh and there is nothing dangerous about it at all...nitrogen is an inert gas, and is what composes about 75% of the air we breathe

i know at my work, the nitrogen filtration machine is calibrated for about 98.5% pure nitrogen. for the effects to be noticed, it has to be 97 or 95% nitrogen in your tires.
im surprized canadian tire would even spring for one of those systems, i didnt think they could afford it.
Injection is nice but id rather be BLOWN!
I hear that nitrogen in the future will more than likely be replacing air, and instead of using PSI, we will use either kPa or Bar.

that Nitrogen in tires is pure CRAP, the air is 80% nitrogen already, so what is another 20% gonna do, NOTHING! i just see it as a money making scam by Dunn TIre and other places of the like. This may make a difference in high powered cars like in NASCAR and in the NHRA, but not in any street car.
Ill make a sig someday
ive used nitrogen in my tires for the past 2 years. I paid $30 for the first delflate/inflate job then i get free Delivered nitro fills anywhere i am.

Same with our F-16's in the USAF, roughly 300psi..

we'll use kpa or bar when america goes metric. pounds per sqare inch will be meaningless when we go metric

Hey Everyone
I just got nirogen into my new tires yesterday and i got 99.4% nitrogen gas into my tires and it ride different then oxygen air they suck at it. NITROGEN R THE BEST AND U COULDN'T BELIEVE IT !
OMG ! It wouldn't matter if you filled them with helium they will still ride the same. Geeez ! Thats like saying Exxon gas makes the car feel so much more powerful then Shell gas does, It doesn't make any sence at all !
Besides even if they replace 99.9% with nitrogen all it takes is that .1% to convert the nitrogen back into oxygen so unless they're filling these tires in the void of space your still getting oxygen
Semper Fi SAINT. May you rest in peace.
^^^^Agreed!

the main benefit to nitrogen in your tires is they do not fluctuate the pressure due to friction and heat build up AS MUCH as air.
less fluctuation means less expansion of the tire. the less the tire expands, the closer to cold tire pressure you are which equals less rolling resistance.
personally, i havent noticed any drive difference except for the fact that the pressure holds better. i have to check it less frequently and the tires dont expand so much when they are hot, so theres no huge benefit, but its free and better than air.
as for it being a money making scam, my work does not charge for putting in nitrogen into tires. it is a free service. it is plummed into our machines as it is, so it goes in while we install the tires.
it is more of a safety thing. we all know that 90% of the people on the road DO NOT check their tire pressure regulairly. it is them that the nitrogen will mostly benefit. i have been driving with nitrogen in my tires for about a year and a half to two years now. i dont even remember what it is like to drive on normal air now.
my boss recently installed air shocks into his truck. he emptied out the air and replaced it with nitrogen because the pressure with the air was higher than what he wanted once the shocks got warm.
i rotate my tire about every 2 or 3 months. when i check my pressure, it is only off by about 2 psi.
as for everyone using kPa instead of PSI? well who knows. it depends what exactly you are talking about. the gauges at my work show PSI, BARs, and kPa's. some vehicle manufacturers, mostly VW list there pressure in KPA and BAR. if you look on your spare, it should be listed in KPA and then (PSI). Canada is already metric and we are still using PSI.
anyways, thats my little rant.

The reason is that the pressure is not suppose to change when the temp in the tires change. That is what I read about it at Discount Tire.

The bottom line here is that there are advantages to using nitrogen, but none worth paying money for. So if you get it for free, then there's no harm in using it but you're not going to get your money's worth if you have to spend actual money on it.
As for BAR vs. PSI... they're two different measurements of the exact same thing. It's like inches vs. cm. Using nitrogen doesn't have anything to do with changing the way you measure your pressure.
