Nitrogen in tires

[Fkellym3]

Nitrogen in tires is becoming a popular replacement for standard air. Nitrogen is all around us... the air we breathe is 78% nitrogen, 21% oxygen and the rest is small amounts of other gasses. When it comes to tire inflation, nitrogen has many advantages over oxygen. With nitrogen tire inflation, improvements can be noted in a vehicle's handling, fuel efficiency and tire life through better tire pressure retention, improved fuel economy and cooler running tire temperatures.


A colorless, odorless, and tasteless gas , nitrogen could cost you as much as $10 a tire.

Most expensive air filled in my m3 tires..

I paid 40 dollars plus tax at the Fairfax BMW Service..


do any of you have one?

Pure nitrogen (as opposed to 78% nitrogen in air, as you state) will NOT improve handling, with the exception extreme (racing) conditions. Nitrogen is used in racing tires to reduce pressure fluctuations due to potential steam build up at very high temps.

Nitrogen will NOT reduce tread wear, which is the typical reason for tires wearing out. What nitrogen will do is escape from the tire about 50% slower than air (from the studies I've seen). This is not a factor if you check and adjust your air pressures on a reasonable schedule (e.g., once a month). It is purported that nitrogen will not oxidize the inside of the tire as fast as air, but this is such a slow process that physical wear will claim the tire first, and the outside of the tire is subject to more oxidation from the sun and atmosphere.

Nitrogen for street use is just a profit item for dealers.

even some Costco places are putting on Nitro on their tire changes too.
but havent tried it yet

As I stated, it's just a gimmick for street use. It is a superior fill, but tires in street use won't know it from air. Extreme conditions as in hard track use or racing is a different story.

Greg is right. Dont waste your time or money. Unless of course you are filling track tires, then spend the extra money.

I had to replace my rear tires after 4500 miles due to nails. Nitrogen would not have prevented that.

sorry..didnt get back to you guys..


I hear you Greg..

now I feel like I wanna take the nitrogen out of my tires and put in a regular air...

I assume that was tongue in cheek! Certainly no disadvantage to pure nitrogen, other than cost. My ulitimate garage would have a nitrogen generator in it!

I read on another forum that a guy did that for only $200.

You can get a cylinder of nitrogen for that much, but don't think there are generators that inexpensive.

cant see paying $30 a dealer for it either, but if they put it in Pro-Bono I wont mind seeing the difference

I had costco put in Nitrogen, then I did donuts in their parking lot to say "thank you"

lolz KRISPY CREME FOR THE WIN !

lol

EDIT ADD: found out MR. TIRES uses nitrogen too

[ase2dais]

Still think Nitro is better after checking my warm tires yesterday, it creep up by as much as 5psi

I think its definitely worth it, if it keeps the the tire in fairly constant pressure most of the time, but now wondering how much Tire shops charges to put them in for you if you didnt buy the tires there
