Nitrogen In tires

[fjwagner]

air is 78% nitrogen, so do yourself a favor and do not pay extra for a N2 fill when asked by the dealer.

[iluvmyVersa08]

Lol, well my dealership does not have nitrogen on site anyways. But so far I have not had to fill them once.

My local Giant has an air compressor you can use for free at the gas station. I just check it at home and if it needs it, put air in the tires. My giant is close enough by that my tire pressure isn't affected by friction.

[iluvmyVersa08]

Are your tires filled with nitrogen? I don't really understand what you are trying to say.

My dad has a compressor at home as well but we can't use that to fill my tires.

[IMHungry]

Scam. Period.

[iluvmyVersa08]

Lol, really. Did your tires come with nitrogen in them? Mine did. When I asked at Plaza about it they had no idea. One of the girls thought I bought my car somewhere else. I was like, "No I bought the car from you guys". Still to this day, no one there has any idea about nitrogen. I asked them many times if it was okay to mix nitro w/ regular compressed air and they had no clue. My dad said if I have to he'll just add the regular compressed air. I don't want to have to pay for nitrogen. But so far they seem to hold their form and not leak. I haven't lost one bit of nitro from the tires. My dad just checked them today and they were perfect.

still totally unnecessary on a street car.

Mixing nitrogen with compressed air is harmless, as fjwagner mentioned, air is 78% nitrogen anyway. I have no empirical evidence as to whether using n2 is better than compressed air, but I check and top off all four tires on each of my cars every month. I already have a compressor with a great filler/gauge, so it is fast, easy and free.

When I bought my wheels and tires, they came filled with Nitrogen.

I notice no difference

At TireTrends™ we offer free Nitrogen inflation on any purchase of a Tire & Wheel Package. You have invested a significant amount of money and we want you to experience optimum performance and service life.

Why should you choose Nitrogen over regular air inflation?

Better air pressure retention. The single biggest reason for tire failure is lack of maintenance of tire pressure. In fact, 54 percent of all vehicles on the road have low tire pressure. Oxygen in compressed air can permeate the tire wall reducing tire pressure. With nitrogen, diffusion is 30 to 40 percent slower than oxygen. As a result, nitrogen maintains tire pressure longer than ambient air.

Enhanced fuel economy. Maintaining tire pressure can boost fuel economy by as much as 6 percent. Nitrogen disperses heat more quickly than ambient air. By restraining the heat in the tire and reducing rolling resistance, you get better fuel economy.

Longer tread life. With quicker heat dispersion, you get a cooler running tire which helps extend tread life and reduce tire failure. Nitrogen also prevents oxidation which can not only lead to tread separation and belt failure but, when combined with moisture, corrode rims. In fact, moisture can result in rust flakes that can fall into the valve stem, block the valve and cause under-pressurization. It can even cause the valve stem itself to rust.

Slows chemical aging. Filling a tire with nitrogen also significantly slows the chemical aging process of the tire's rubber components. This leads to fewer catastrophic failures like blowouts. Slower aging lengthens tire core life, which yields extra retreads and lower fleet costs.

What is a Nitrogen Generator? Nitrogen Generators employ advanced membrane technology for flawless performance, day in and day out. Nitrogen Generators are comprised of a bundle of hollow-fiber membranes that separate nitrogen from the air. When the compressed air passes through the fibers, oxygen and other trace gases permeate the membrane, due to their smaller molecular size and higher molecular bond strength. Nitrogen, which doesn't permeate the membrane, flows through the outlet port to the application.

I'm saying it's fairly easy to find air compressors around enough to negate any real advantage Nitrogen has.

Our compressor works, I just meant that it does not fill my tires with nitrogen.

[Red Devil]

I know, neither do any of the AIR compressors I use.

[iluvmyVersa08]

Lol, yes I understand that ... If I need to ever fill the tires, I might just mix the nitro w/ the air. Depends if I can get nitrogen free, if not I'll just fill it at home.

[ADOversa]

My car came with it from the dealer.

They have told me that they have added air to the tires before... so I am kinda wondering if they put in air or n2, as I got to the same dealer as iluvmyversa08 and she pointed out they don't have nitrogen there lol.

[iluvmyVersa08]

Lol really? Hmm ... well the last time I asked them was before my road trip around August 2008. I haven't asked them since so maybe they did get nitrogen in. Did your tires valve caps indicate nitrogen on them? Does your front windshield have a nitrogen sticker that says "this car rides on nitrogen"?I bought my car at Plaza but it was brought in from somewhere else as they didn't have a red one w/ the sport/tech package available there.That is weird because they told me that you cannot mix nitrogen with air and from what you are saying it sounds as if they did. Hmm ... I guess if I ever need to fill them I'll just add air at home. I'm surprised though that if you have nitrogen filled tires you would already need the tires to be filled. I checked my tires the other day and the pressure was perfect so we haven't had to fill them since I bought the car.

[ADOversa]

Yeah I've got the window sticker and the valve caps. Maybe they did get Nitrogen in? Maybe IMhungry can chime in here?

I can't see a problem with mixing nitrogen and air... because as was mentioned probably 10 times already, air is mostly nitrogen anyways.

[iluvmyVersa08]

Ya I think it wouldn't harm anything to mix it. It's just weird that you have had to fill them already. Mine still have the same pressure as when I bought the car.Did they charge you to fill your tires (if it was in fact nitrogen they put in). If they did mix air into them then they are contradicting what they told me. They told me last summer that I couldn't mix the two. So if they did for your tires then I will in the future for mine!

[ADOversa]

They didn't charge me anything for it, I beleive it is covered under the road hazard warranty. They found a tire to be slightly underinflated so they topped it up, and another tire had a nail in it so they replaced the tire free under the road hazard warranty. I never asked what the filled it with though... kinda makes me wonder.

I will repeat this for the third time. Air is 78% Nitrogen so how could mixing the two be a problem. People, this is a racket to make money. N2 is not some magic tire fill at at all. Fred

O RLY???

[fjwagner]

O RLY???

... and what do you mean by that?

[ADOversa]

Just a little joke man. No offense intended.

I think her point was that the dealership told her one thing when it looks like they may have done the opposite in my car, not that she beleives that.

[fjwagner]

No problem. Was not sure where you were coming from. I just do not want to see people ripped off.

[ADOversa]

Cool beans. I totally agree with you that it is just a scam, I would never actually pay to have Nitrogen inflated tires. I'm just kind of wondering if it would throw off the handling having a tire inflated with air instead of nitrogen if the other tires all had nitrogen. My car does have a pull to it, so maybe that could be the reason? Although I kind of doubt it, air really isn't much heavier than nitrogen (spec. gravity of air = 1 spec. gravity of nitrogen is 0.8 I beleive) but who knows... I will probably just fill them up with air.

Yes I understand what you are saying and ADOVERSA thanks for backing me up. I was trying to say that the dealer told me one thing and it seems as though they did the opposite to your car which is weird. I too don't want to pay for nitrogen to fill up my tires.

What has IMHUNGRY said? Does he know if PLAZA has N2 on site now?

[ADOversa]

No worries, probably just a misunderstanding, we are all friends here right?

No IMhungry hasn't said anything yet. I don't really care if there is air or nitrogen in my tires, but I am a little curious now lol.

He did comment earlier in this thread that it is just a scam though. And if anyone would know, I would think he would lol.

Lol, yes I would like to think everyone is friends here. We all do drive the same car! haha!Yes IMHUNGRY would know I guess, he works there. We'll have to see what he says!And I agree w/ you, if I can't get nitrogen free, then I'll just be adding air to the tires when I need to. Thanks for your help!

[ADOversa]

Guess he hasn't checked here in awhile... I'm sure there is a reasonable explaination though, as they have been pretty honest with me in the past. I'm still curious though lol. Have to take my car in for an oil change this week so I will ask then.

[cyberpyr8]

I will repeat. Air is 78% nitrogen!!!!

So I should only pay to fill 22% of my tires with nitrogen?

Unless you are seriously racing, nitrogen in consumer tires is a scam. Just another way for shops and car dealers to get more money from you. I had nitrogen in my tires of the Jeep we bought and it didn't seem to make any difference in gas mileage. They are now using regular air and doing just fine.
