nitrogen in tires or not?

[camaroincarolina]

Me, too.....I have 14K on mine and they are still in good condition.....

[alcal1084]

what do the tires come with stock?

IMO nitrogen is a big rip off. Air you put in regularly is already over 70% nitrogen

Nitrogen hands down. Not many places have it so make sure that it won't be a hassle if you do need a few more pounds in your tires. Costco is the only place in Salem, OR with nitrogen, but it's right on my way to work. I've only had to stop there one to get some added nitrogen after buying the car but they had it done in less than 5 mins. No hassle at all to take care of my baby.

I have 6500 miles on my tires. The front tires are in excellent condition. The back tires need a good bit of help

[BackinBlackSS/RS]

Been driving for years. Got along just fine without nitrogen. Never had any tire issues.
I think I'll pass.

So, you're just using regular air, huh!! Smarta$$!! LOL

That being said, you have to have at least 95% Nitrogen in your tires for there to be any benefit. It usually takes at least 3 times purging out the air and filling with pure Nitrogen to achieve 95%.

Why Inflate with NitroFill™?
Compressed air is your tire’s worst enemy. Air is about 78% nitrogen, 21% oxygen, and 1% other. Nitrogen is inert, non combustible and non corrosive. Oxygen, on the other hand, is immensely destructive to rubber and other tire materials. As soon as a tire is manufactured and exposed to air, the effects of “oxidation” begin to deteriorate the rubber. Over time it loses its elasticity and strength, just like an old rubber band you’ve probably found around your home. This same process occurs in tires inflated with air as the oxygen attacks the rubber molecules, working from the inside out, until the oxygen, and its destructive properties, permeates the tire structure and ultimately the tread.

Is All Nitrogen Gas Equal?
No, the purity of nitrogen available from nitrogen generators generally ranges from 95% (low purity) to 99.9% (high purity). NitroFill™ generators can produce nitrogen in excess of 99.9% purity and provide the procedures to guarantee a minimum of 95% purity in the serviced tire, which is the minimum allowable purity that must be maintained in the tire to enjoy the benefits that nitrogen provides. Few generator manufacturers currently discuss this mandatory 95% threshold, as few are able to consistently provide the required purity to achieve it. But, as the market matures, your customer WILL learn –so don’t take chances with their safety or your reputation- fill them with NitroFill™ !

My Tires are Low! Now What?
Low tire pressure is generally due to one of the following three conditions:

1. A leak. Most tire leaks are the result of a hole or puncture, faulty valve, or a porous or corroded wheel.
2. Permeation. Permeation is the normal process by which the air in a tire bleeds through the tire’s body or carcass. It is typical for an "air" filled tire to lose 1-2 psi of pressure every month through normal permeation whereas it can take several months for a NitroFilled tire to lose a single pound of pressure.
3. Temperature Change. All gases expand and contract with temperature. If you live in an area that experiences dramatic temperature changes, you will have to adjust your tire pressure accordingly. Typically you will only have to adjust your tire pressure "up", adding pressure as ambient temperatures decrease. Count on losing about 2% of your total tire pressure for every 10 degrees in temperature reduction.

But the big thing about Nitorgen is unlike regular air Nitrogen has two advantages. Besides keeping a constant tire pressure Pure Nitrogen also has less moisture content than regular air. What does this mean? As the tire gets warmer the moisture in the tire is vaporized causing expansion and an increase in pressure. In a Nitrogen inflated tire the lesser moisture content of the nitrogen makes it less likely to change pressure as the temperature changes which is important because even a slight change or variation of pressure can affect the cars handling. In addition the use of Nitrogen can also help avoid the oxidation of the the inner tire liner and the wheel which can occur with oxygen. However nitrogen is not cheap so some thought about how much money you'll spend should be a consideration before using nitrogen permanently

The dealership where I bought my car does it for $5 a tire. When I get the Camaro back out I'll probably have it put in.

Would you be intrested in a bridge?

I always find this debate funny. There is one reason that race teams use nitrogen. Consistency. Air is not a consistent mix of gases. What that means is that air expands and contracts at different rates when heated and cooled.

In a race car they measure PSI in 1/4 increments and small changes in pressure can mean the difference between a well handling race car and one in the wall. Knowing how much the pressure increases when heating the gas in the tire 10 degrees is a must. (And the rate of expansion of pure nitrogen is very easy to figure out. It is cheap, common and inert so that is why they use it.)

So.... unless you are measuring the gas in your tire to the 1/4 pound while you are driving on the very edge of the cars capability and that last .01 of a second means the difference between a million dollar payday and losing a race. Nitrogen is not needed.... but if it makes you feel better put it in and spend the extra $$.

Me I will stick with free air just like GM spec'd for the car.

[jtzako]

"Air" is already something ilke 78% Nitrogen. Why would you need/want to pay more to get an extra 22%?
I just dont think it would make a big enough difference in any way to justify the cost unless you get it for free.

Nitrogen at 98%-99% levels has several benefits. The biggest of which is being a larger molecule than oxygen. Air loss in a tire can be up to 10% a month. The larger nitrogen molecule has a much harder time leaking out through the rubber tire membrane. Example, helium is a very small molecule and leaks from a balloon much quicker than air, we've all seen that. At a 10% leak down if you don't top off your tire pressure at the very least monthly then you will experience wear caused by under inflation. Nitrogen is more stable in tempature changes, and is moisture displacing which can prevent rust on chrome or steel wheels. It's not for everyone but does have advantages.
We ran a test on my mini cooper last year when we purchased a nitrogen generator at my store. We put 36 pounds in all four tires March 1st. Four months to the day later we checked the pressures for the first time and it was 35 psi in each. Not bad losing only 1 pound in 4 months. Nitrogen is not a substitute for checking your pressure regularly. Nitrogen is also used in airplane tires and struts for the very same reasons. It is a pain when you need a top off.
