Who runs Nitrogen in their tires??

[skeeters65]

Title says it all...



Do you see any benefit?? Pros/Cons

My tires are already mounted but the local GM dealership said they can evacuate the air and re-fill with Nitrogen for $49.00..
Is it worth it??


Thanks

$3-$4 per wheel is standard, $49 is absurd. I use it to maintain accurate pressure since my cars a rarely driven. Also have it in my dialy driver (Cadillac DTS) It's worth $15 - $20 bucks but not half a "Ben"

$49 is absurd. It is not that expensive. Nitrogen has lots of benefits. It does not change density with temperature changes so your tire pressure remains constant, and can increase fuel economy by maintaining the correct psi. By maintaining the proper psi will also prolong tire life. It does not absorb moisture either. I had a few other positives but they escape me.

Lots of benefits, but not worth it for a street car.

They also said for the $49.00 you get free Nitrogen for the life of the tires.. Even evacuate them if you need to add air in a pinch..

Thanks

Then you would need to evacuate them about 4 times to make it a good deal. Call your local Wal-Mart or go to a "quickie" oil change place and get it done for $12-$16, at the oil change place they will appreciate your business and more than likely replenish you with air for free if ever needed.

my wife's new tires on her G-6 were filled up with Nitrogen at Big "O" tires. no extra charge.

That about sums it up.

Costco has nitrogen also. We drain and refill for free at my store but some locations may charge a small fee. It varies by area.

People with way to much money and those with access to free nitrogen... Oh and those in real cold climates.

lets see, nitrogen makes up what percentage of the air we breathe? quite a bit if memory serves. we all have it already just not 100%.

I run nitrogen in my Mustang's tires. I don't really notice any difference. It's annoying as i can't air up my tires from the compressor at home. Most tire shops should be able to do it for a better price.

Air is composed of about 80% nitrogen, 19% oxygen and 1% trace gases. No need to quibble over a percent or two of gas composition.

My understanding is the advantage of nitrogen is it's commercially dry, vs air which carries water vapor. The water vapor or humidity in the tire air is where I understand the big variation in pressure vs temp occurs.

Thanks great info!

Thanks great info!

x2 Thanks!

Ok big trick is when tires are mounted the tire is then deflated and refilled with pure nitrogen, the minor amout of air is negligible but the reason for nitrogen is the molecules are larger not allowing them to pass out of tire like oxygen.
So the more nitrogen in the tire the less likely to have low tire issues. Also if you do have to air a nitrogen filled tire, fill it as your not going to mess anything up by topping the tire with home compressor.
Another benefit is the lack of expansion/contraction over plain air, and yes it is much drier.
Honestly I feel the tire stores should use air driers in thier system anyway.
As for 50 bucks pass.

Edit: the 49 dollars is for labor not the nitrogen, as the bottle can be rented from local welding shop for cheap and regualtors are cheap. If I ever open my own shop I may offer it but wont super charge for it.

I have a question? I sometimes run a pair of MT Drag radials on the rearother times I run the Toyo R888 Track day tyres. If I set my tyre pressure and then burnout. Will the pressure remain constant if they are nitrogen filled?

[Samckitt]

Tire Barn says they put it in the tires on my truck when I got new ones. Can't say that I noticed anything different, I think it is snake oil. For a race car, where they get extremely hot, then yeah maybe it makes a difference.

Normal air that we breathe contains: (rounded to the nearest %)
Nitrogen 78%
Oxygen 21%
Argon 1%
And a bunch of other traces.

So 22% of the air in out tires are not nitrogen anyway.

Commercially dry nitrogen is orders of magnitude drier than you can get with an air drier. Air is pump up to high pressure, allowed to cool, and run through an orfice dopping pressure (and temperature). Stuff like water and high complex gases condense out first, nitrogen will condense out at about -300F. By that time there is very little water left in the mix

Thats what I want to know??
