What the big deal with Nitrogen Filled tires? Does it do anything for the ride? Are there any real advantages to it? All i've heard was that they keep tires from rotting from the inside out since theres no cooling of the compressed air and with that no moisture???

Any ideas??....Comments? Is it worth $12 at Costco?

 

i would like to know more about this too

 

nitrogen doesn't expand/contract as much as air does due to temperature changes.

 

...therefore you have a consistant pressure throughout the day/year. Consistant pressure means consistant handling. The car will corner and make the same road noise during the cold, early morning drive to work as it will during the warmer afternoon drive home. Personally I wouldn't bother unless I had expensive rubber on my car.

 

good to know...

 

What happens if it leaks by a flame. Nitrogen burns quiet easily... I know the odds aren't great of happening but still...

 

We sell it at work, I'm not sold on it. I put it in my tires and they fluctuate as much if not more than air did. They claim it improves mpg by lowering operating temps and maintaining consistent pressure even at higher temps. Larger molecules than oxygen, it supposedly is less suceptible to escaping the tire if punctured slightly or through pores in the tire. There has been supposed conclusive evidence proven by long term testing in trucking companies etc. Clemson did some in depth study on this.

 

Did you do it the correct way? Our machine at work takes about 15-20min to do the job. If you're just letting all the air out of the tires and then filling it with nitrogen I believe there is only about 70% nitrogen in the tires.

I have it in my tires but I can't honestly say I can tell a difference although when I put the nitrogen in it was on a new set of tires.

If any one in the Austin area wants nitrogen their tires (free) and will post back with their opinion shoot me a PM.

 

You sure you aren't mistaking it with hydrogen? nitrogen isn't flammable that I know of... most of our atmosphere is nitrogen. Pretty sure remembering in school that nitrogen is an inert gas.

 

There are a couple places I just noticed recently that have signs advertising it.

 

Marketing gimick...just do a quick Google search and see what air mostly contains.

 

Did you fail chemistry?

 

LOL

Nitrogen is the opposite of very flammable.

 

I thought the bottled nitrogen has no water vapor in it, so the pressure stays a little more constant as opposed to regular compressed air that does contain water vapor.

Nitrogen should expand and contract with temps similarly to dry air. Air is like 70%+ nitrogen anyway.

 

From what I have read with our machine and when done correctly the tires will have 98% nitrogen.

 

If no one takes me up on my offer and if I have time tomorrow I will deflate my tires and put just air in the tires and drive around for a few days and report back.

 

I had mine done recently and they took the tire to a machine that (not sure if it pumps or not) takes air out and replaces it with nitrogen. I have only had it for a few weeks, but from what i can tell the tires feel like they are full all the time day or night. Usually my tires would loose a little psi depending on temp. Is it a marketing thing could be, but if i had to do it again i would. (they do free refills for the life of the tire)

 

Yes, I did it right. The machine does it all, it's a cycling process. The air you breathe is 79% N2, our machine ends up making your tires have 95% N2. I've seen some local tire shops do some that come through and theirs only have 91%. I'm just not sold on it for cold weather. It may also be affected by the brand and size of tire. We got it to try to alleviate us getting beat up by all the moron customers who drive in with their low tire pressure light on like it's a warranty problem and what an inconvience. It's like checking their air is not their responsibility.

 

my friend put it in for free for me once, but then i went to the track and wanted to drop the pressure. so i ended up filling it up with regular later. didnt seem a whole lot different, and not really worth the hassle. with normal air u can fill up anywhere.

 

I hope no one lights a match or we're all screwed.
