The dealer wants $50 to nitrofill 4 tires.

Too much shop around I spent $20 to get my Vette done.

I personally do not believe in the nitrogen fill. With 78% of our air being nitrogen and I just don't think that it is worth the cost.
Even with nitrogen and tpms you still should use a good tire gauge and check the cold tire pressure .

Ya know lots of people who have never tried it call it a scam. Let me enlighten you.

Nitrogen does not have moisture in it which was the reason I used it my Chrome rims on my Vette were bubbling (corroding ) at the bead causing leaks.

Nitrogen does not expand and contract like air as I said the difference between summer here (100deg) and winter (below 32 deg) is 1 - 2 lbs vs 3-5lbs for air

Nitrogen does not seep through the rubber (or around the bead) like oxygen. That is the main reason tires hold pressure for longer periods with Nitrogen. I have lost 1 lb in 8 months. This is because Nitrogen molecules are larger than O2.

The expansion after tire warm up is less causing the tire to actually wear better and increase gas milage.

Say what you will but NASCAR uses it for more than 1 reason.

Just thinking about the argument of the Oxygen molecule versus the Nitrogen molecule seeping through the rubber...Well, if we start out with 20% Oxygen and 80% Nitrogen, eventually the small Oxygen molecule will sneak out of the tire and all we will have left is fat-a$$ Nitrogen Molecules getting us to where we want to be - and it will be for free ! Granted, it will take awhile, and we'll never get to 100% Nitrogen because we keep topping off with 20% skinny Oxygen Molecules, but we'll get pretty close...eventually !

I tried nitro fill only because I bought tires from a dealer that used it. I can say with 100% confidence that I saw no advantage over air. They still had to be topped off like standard air. this was a newer car with wheels that were in great shape.

I would never pay extra to switch to a nitro fill. All marketing hype IMO.

Those weren't myths but pretty much confirmed what I said It is better than air. All air has humidity in it it leaks out faster and needs checking more often etc etc....
it is only better by a small percentage[size=10pt][size=10pt] IF [/size][/size]all the requirements are met. the main benifit is less air filling. LOL who cares? i have a compressor in my garage and an up to date TPM. why pay? save the $$ and buy an air compressor.

Nitrogen is good in some applications. Race cars use it mostly for pressure stability. Moist plain old air expands with heat, nitrogen does not. I used it when I was drag racing my Harley Sportster. Not so much in the tires, but for the air shifter. It kept the shifter parts cleaner. Would I use it in car tires? Only if it was free.

:thumb: Yep...if your store offers it as a free service...go for it.

I think where most people are getting thrown off - is the actual process of Nitro filling itself.
Mochaman is correct - the trouble is that some retailers may not be following the proper procedure. The tire has to be under extreme vacuum first then filled.
In my local area one retailer charges $5, its cheap because after questioning, they weren't following procedure nor had the right equipment to do so.
So, if done correctly, its a major improvment with multiple benefits as mentioned in this thread.

incorrect. minor benefits. the only real one is not having to inflate your tires more than 4x a year. seams hardly worth it especially if its $5 each wheel x4 x3 a year. Read my pdf.

the 1 benefit is they don't go down in pressure as quickly as regular air filled tires and you fill them less times a year. however we all have TPM on our wheels so who cares? When its low the TPM tells you and you add air which negates the reason of filling them with Nitrogen ie slow leaks. So the one benefit you would see is your tire pressures not increasing like regular air.

I worked in the Air Force as an aircraft mechanic as a wheel/tire specialist for the B-52 bomber (700lbs for each wheel/tire combination!!). All military aircraft tires are nitrogen filled. As some other posts stated, there are some applications where it makes a difference, such as military aircraft and NASCAR. Commuter vehicles see such a small (if any) benefit, that it's not worth the money. Put it this way, even if you find a deal for nitro at $20 you could buy your own baby compressor for slightly more and always have perfectly filled tires.

Personal experience: I have driven my cars from CA to MI to LA to WA several times and didn't have to adjust tire pressure at all. Think about the humidity differences between those states during summertime. Nitrogen is not necessary, but having your own compressor is fantastic.

I think the issue for pressure differences/air loss is because of temperature changes, not humidity differences.

Well both actually, DeKnurla is just making a reference to humidity instead of directly applying temperature into the equation I think.
As temperature and humidity are directly related to each other.
Simply put,
Warm air is usually more humid than cold air, so the higher the humidity - the warmer the air, hence higher ambiant pressures.
With lower humidity - brings lower temps. hence lower ambiant pressures.

Now you can apply;
With lower temps. brings lower air pressure in the tire,
With higher temps. brings higher pressure in the tire.

Just my thoughts[/color]
