Anyone use nitrogen in their tires instead of air? It's supposed to hold tire pressure much longer than air and give a better ride. At least that's what the guy on the news said. Opinions? They said that it’s safe to mix the air and nitrogen if you ever need to fill the tire in an emergency.

 

Isn't air 80% nitrogen anyways? I think this is just another way to squeeze you for a few bucks.

Edit Sorry it's 78%:

 

Been doing it for 2 years now. I was nervous at first but now I love. For 6 months I havent had to add any air/Nitro to my tires at all. If they do get a little low (rare), you can add air to them.

They've been doing this in Nascar for awhile.

 

where and how?

 

what about helium?

 

im pretty sure COSTCO is filling all of the air with nitrogen~

 

it's very common in race cars, because the temps dont' fluctuate as much

 

Is the only benefit that you don't have to refill/check pressure as often?

What other benefits are there?

 

Aircraft tires are filled with nitrogen. It does not allow the moisture in the air to condense inside the tires. That moisture can settle into one area of the tire at high altitude and freeze and cause a severe out of balance condition upon landing.

 

Screw that... All the cool kids use hydrogen.

 

Oh, and another thing. It doesn't expand and contract as much either. So the pressure stays more constant with changes in temperature.

 

My CL is great and all, but I'm not so worried about this happening with air in my tires.

So, this means...? Is it a measurable/material difference in mpg or something? I assume it would help with tire wear a little, but not sure how much.

 

Nitrogen is complete overkill for 99.9% of people.

 

Nitrogen is somewhat less able to escape through rubber than some of the other gases in compressed air. So there is a bit more stablity.

It is a bit less sensitive to temperature, but within the normal operating range of street tire temps that's unlikely to be an issue.

Aircraft tires use nitrogen because it is guaranteed 100% dry, so the issue of condensation at very low temperatures experienced at altitude disappears with nitrogen. In truth, any completely dry gas would achieve the same result, but nitrogen is used because it is relatively cheap and also inert.

 

hmm, first i've heard of that. i might give it a shot, see where it takes me.

I think it may be a bit over-kill. They also say that it will increase your gas milage by reducing road resistance.

Yea that's what I heard. It's the newest thing. Makes the ride less bumpy.

 

Does it add HP?

 

It might add 5 more hp than my type-r sticker

 

i believe its

If it were easily available, and cheap, I'd fill all my tires, and the tires of my parents, sister, girlfriend, etc with it.

Why? Because they never check their pressures, and the only time it is checked is when I do it every so often, only after noticing a severely deflated tire.

On my 19's if it does leak less, Id use it just to make sure I am always up to the proper PSI which would make me less prone to bends.

So the $100 question is, where do you find Nitrogen gas that can be used to fill your tires?

 

Keep reading, you missed the 2nd half of that statement. The Nitrogen leaks less than regular air which means your tires will stay properly inflated. Properly inflated tires decrease rolling resistance, not the gas inside them.

 

I only fill my tires with air directly from the supple, pink lungs of a baby panda bear aged 6 months or less. And not one of those ghetto captive/zoo pandas, either.

 

what about no air at all

Retard. EVERYONE knows it's 78%.

80% hahah ur lame.

 

I try to be accurate but sometimes I slip up.

 

That's the last time I believe something Dan Martin posts. :shakehead

 

 

 

 

I just check my tires a couple of times a month. Besides, tire pressure changes as climatal conditions do, so you still need to deflate or inflate the tires to the proper pressure. Sounds like a bunch of hype and waste of time and money to me.

 

Dude, you guys are idiots. In order to have 99.99999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999 99999999999999999999999999999999999999999999999999 9999999999999999999999999999999976 % of people you must have a minimum of 10^150 people. There has never been so many people in the history of the universe and nor will there ever be (heck, this number is larger than the number of atoms in the universe).

 

 

Unless you cut them into little pieces....

 

the million dollar question is not where do you get N2, but how do you fill your tire to 100% Nitrogen??

 

You don't. Most of the machines at dealers, shops, etc fill to around 92% N2. The dealer I worked for (where I get my car serviced) has a machine that does it to 97%. I've been using it for a couple months now. Haven't had even a 1/10th psi variance. I'm completely ok with having consistent tire pressure (especially with all the miles I put on the car), less temperature variation, and less hassle. I do think that you do pay a bit for doing it. After some time, it will cost nothing to do. Places just have to pay off the machine.

 

It's very common in race cars, most use nitrogen. Doesn't escape as easily and doesn't fluctuate as much when the tires are warm. Most of the guys I detail cars for swear by it

 

BTW, many tire shops are starting to carry it, I think all costcos carry it

 

I just watched this video:

http://www.n2revolution.com/

and in there they state that if you are a costco member you can go there and fill up your tires for free with nitrogen even if you haven't bought tires from them.
