Tires filled with nitrogen boosts mileage. Is it worth filling @ $20?

If you are an individual that checks your tire air pressure regularly I can't see the value in nitrogen in tires. Personally, I feel its another gimmick but if a company such as Costco will initially fill new tires purchased and then "top off" as required, fix and refill tires after flats, and not out in any way out of your normal daily drive then what the heck- go for it.

BORSHT asks: How much of an increase in ecconomy should one expect?
____
Nitrogen provides no benefit against a properly inflated tire with air. The advantages of nitrogen include the ability of the tire to maintain pressure which means more convenience, avoidance of the potential corrosive effects on the tube with oxygen, and less radical changes in pressure due to temperature.

If you always keep your tire pressures checked, nitrogen is of little value. If, like many, they are checked during every blue moon, nitrogen can save on gas and treadwear as a function of underinflation.

One poster writes: Wherever you buy your tires should re-inflate them with Nitrogen for nothing if they use Nitrogen. Otherwise I am not sure it will be that much of an impact and certainly not enough to offset the $20 you mention above.
______
Too often, people look at the immediate cost of something and make a decision on that one factor. In this case I think it's a mistake. A set of radial tires can last 40-60K miles these days. That's several years for most drivers and in that time they will have to check and possibly add air to those tires at least once a month if they want to keep the tires at the proper PSI. If nitrogen cuts the frequency by half, that certainly seems worth $20 to me.

Also, while COSTCO may provide nitrogen free of charge, others may feel the need to charge something since the nitrogen machine does cost money to purchase and maintain.

When one buys tires @ COSTCO they automatically fill w/nitro.

Houckster nailed the situation exactly. I never believed in this magic gas myself but reading the postings here, doing a bit of research on leakage rates, and finally admitting to myself that I rarely check my tire pressures, I've concluded that Nitrogen has a very positive effect for the "average" car owner.

Of course, I haven't installed N2 yet, but admitting the reality is the first, and biggest, step.

Sorry. This kind of air-headed thinking is one of the biggest problems in our country. The reality: If you're accustomed to regularly checking your tire pressure, nitrogen won't provide much value BUT since most people don't check their tire pressures often AND because when they do, they inflate to the OEM recommendation which is really the minimum safe inflation most people are driving on underinflated tires. The value of tires that retain their pressure more effectively and the gas not lost from underinflated tires is not to be overlooked.

If you are driving an industrial mining dump truck, then you need to fill the tires with nitrogen to prevent them from starting on fice and exploding. Otherwise, you are wasting your money.

I think Houckster has nailed this argument right through the eye.

Nitrogen does nothing over standard air IF you keep your tires inflated. For those who ignore their tires for months at a time, Nitrogen will maintain pressures a bit better.

If you pay attention to what your car/truck needs and wants, nitrogen is a time and, if you pay for the stuff, a money waster.

Now you have to decide if you pay attention to your tires and keep them very happy or if you will ignore your tires and let Nitrogen cover off a bit of your laziness.

Actually it does. Most people inflate their tires to the OEM recommendation and then forget about them for months. Consequently most people are driving on underinflated tires.

Nitrogen, in a properly mounted tire, will not seep quickly through the tube so people will drive on tires much closer to proper inflation much more of the time and that will save gas.

No... Nitrogen does nothing for fuel economy... It is used in military vehicles since it will not explode when in contact with flames.

I'm not sure they are worth the extra money. I have Lo-Profile tires & I have about 90k miles on them & still have good tread. I have the tires for life program with Chev. dealership in Virginia & can't them worn down enough to replace. I now live in FL. & they do not transfer the deal for the car. So, I either have to go back to Hampton, VA for a visit or buy my own tires.

I believe it was early summer when the tires in question were mounted on my vehicle. I really thought the slight deflation was caused by the new valve stems installed,don't really know although I did tighten the core valves on each wheel and capped them after trying the soapy moisture test,the wheels are oem alloy.

No problems since on still the same wheels/tires nearing 75,ooo miles with plenty of tread and no scuffs.I simply reair when needed by a my garage compressor,it has a moisture trap filter.

This sounds a bit strange. Nitrogen should not bleed through the tube as quickly as with air. If the tires lost enough pressure to require refilling, then it seems very likely that the tires were not properly mounted in that there was a defective seal between the tire and the rim. That the tires are holding air now seems to indicate that something more than just adding air occurred when the tires were brought up to proper temperature.

Just a one time event with me,when a new set of tires were mounted,two months later had to add regular air because two of those tires became low inflated.No problems since with reg air added. Mileage wise I haven't noticed any change,but keep track of tire pressure at least monthly.

I have never dismounted a tire in the past that had any moisture inside problems or steel wheel rust,only a small congelled ball of rubber residue rolled up inside by tire motion(debris)sometimes found.

Often I changed only my own tires in the past never found any moisture problems on any runnable wheels,ones that set for long periods of time on undrivable vehicles yes moisture/rust was sometimes seen inside.

Older alloy wheels can corrode/oxidise,causing a sealing problem,slow leaks near rim and bead areas,cleaning/buffing metal often corrects this.

I would say any minor moisture trapped inside a tire gets dissapated threw the tire walls as vapor same as the reg air does over a short time. Any fuel savings I attribute to is due to correct pressure monitoring on a reg basis till tires tread wears out...That's just me....

Anyone used a compressed air drier for tire fill air supply to reduce water content?

Found a simple setup at:

http://www.ecompressedair.com/air-dryers/point-of-use/ds20-point-of-use.aspx

Seems to me that getting the water out of normal air would provide some benefits but haven't heard of it being done.

OMG who charges $20 to fill with Nitro??

I can get a repair and nitro filled for $20 thats including taxes!

I have nitro cause the car came with it, but :

Nitro was mainly used in racing ...helps keep the tires at a more reg.
temp. and because of the stress load more contact patch to the road.

Air is 80% nitro anyways ....if you do go nitro it only works if you can purge the tire 100%

If you ever add air to that tire the benefit is gone again.

(Some) other benefits of nitro are:

-Bigger molecule, less likely to leak.
-Doesn't expand and contract like O2 so in cold/hot weather it's less likely to change tire pressure (over 200km this would change about 2 -3 psi with air)
-Less corrosive (air has more moisture)
-Non combustible
