For a joke I told the boys at the tire barn

Geo-TH,In · Oct 5, 2022

For the past 20+ years, I buy my car and truck tires at the Tire Barn. Every 6000 miles they rotate and balance my tires for FREE.
For a joke I told the boys at the tire barn I need my tires rotated, balanced and to replace the air in my tires with winter air.

Dang if they didn't replace the air, nitrogen.
When they finished my car. I told the guys replacing the air in my tires was a joke..

Guess the joke was on me.

I never told them to replace the air again..

Does nitrogen expand and contract less due to heat and cold?

What per centage of air is nitrogen?

Steve@Advance · Oct 5, 2022

Less expansion and contraction is one of the advantages, used for racing where low pressures are used and track adhesion is critical. Another theory is the nitrogen molecules are larger and tend to not seep out as much as other elements of atmospheric air.

But for everyday street driving it is not a considerable factor.

What I don't understand is how do you inflate a tire with nitrogen and get the moisture and mixed air out that are already in there? You can't vacuum it, the tire will pull off the bead, no way to purge it all out. So even the racers are not really accomplishing anything!

78% nitrogen, 21% oxygen. The other 1% is what the world seems to worry about!

ere's an interesting article from consumer reports that covers the subject well: https://www.consumerreports.org/tire-buying-maintenance/should-you-use-nitrogen-in-car-tires-a6260003694/

If I have 32 psi in my tires at 22 degrees I can see an increase of 1 psi every 10 degree increase.
Yes there is a lot of nitrogen in the air.
Drain your air comp tank and you will see air is full of moisture.
New cars have tire pressure sensors that you might not want to get wet.

Nitrogen expands at a linear rate in my tires.
In winter 33 degrees and 33psi
42 deg 34 psi. 52 35 psi.....
At 92 degrees 39 psi.
I look at my tire pressure and can tell what the temperature is.

Nascar uses nitrogen.

The part they freak out about is about .04% not 4 hundreths but 4 parts per 10,000.

We were bicycling across the Rockies many years ago, and we told one of the girls that she had to stop on top of the Continental Divide and change air in her tires, from west-coast air to east-coast air. Haw haw. We all took off, and several hours later, we came across the gal, trying to pump her tires back up, with the newer east-coast air!!! True story.

We had new tires put on our car recently at Costco, and they put nitrogen in them. I can tell the difference, the pressure doesn't change as much. Tires seem to run very quiet, and are supposed to be very good on wet pavement, Michelin CrossClimate2. They look like tractor tires!
