Wow, it just keeps getting more ridiculous all of the time. However, I
guess if you buy tires at a store like Costco, then you are pretty
gullible to start with and will believe most anything.

I like your logic and use much the same logic. I tend to run my tires
at 35 psi and check them every month or two. I rarely lose more than a
pound a month and that just isn't consequential. And the more times I
add air to my tires, the more pure the nitrogen inside is getting as the
oxygen "leaks" out!

Who said that I bought my tires there? I never bought tires at Costco, the
little shop where I go always have unbeatable prices on tires. Anyway, I had
it for free (Nitrogen inflated tires), so where is the problem?

False. As you add new air, you add 21% of oxygen and 1% of other gases, wich
I don't know what gas it is. So when you add air to you tires, you
contaminate the Nitrogen in it. That's my logic. So you wil always have 78%
of Nitrogen.

How so does this make you gullible? They sell dam good tires there, and
reasonably cheaper than anywhere else. I'll be getting my next set there,
Michelin Energy MX4's. On the other hand, I don't buy into that nitrogen
story either.

False.
If you start out with 78% nitrogen, leak out some oxygen, then replace say,
5% of the total volume with air, the nitrogen is still increasing, albeit by
a smaller amount than adding pure nitrogen. Only 20% of the 5% is oxygen
wile 78% of the 5% is nitrogen.

It isn't the tires, it is the installation. Most places like Costco,
Wally World, etc., don't properly torque the tires and often don't get
them balanced all that well. I use a tire store that advertises that
they use a torque wrench to properly torque the lug nuts and they do as
I've watched them to be sure.

You need to study your physics. If you start out with 80% nitrogen and
20% oxygen (rounding to simply the numbers) and all of the oxygen leaks
out, you have now 100% nitrogen, but your pressure is down by about 20%.
If I now add air to bring the pressure back up to where I started, I
have 80% nitrogen, plus 80% of the 20% air that I just added is
nitrogen, so I now have 96% nitrogen and 4% oxygen am at my normal
pressure again. If all of the oxygen leaks out again, I'm not down only
4% in pressure. So, I add enough air to bring me back to normal
pressure. I now have 96% nitrogen, plus 80% of the 4% air that I added,
which gives me 99.2% nitrogen. I will asymptotically approach 100%
nitrogen, however, even after one cycle I have as pure a nitrogen fill
as the Ford article claims was adequate.

Ed, I think this is a lost cause. Folks that get their tire information

Costco does the same thing. 80 lbs on my 2006 Sonata V6 when they rotate the
wheels.

And what if I didn't even bought my tires there? My tires doesn't come from
Costco, and they charged me a big 0$ So the price of their tires doesn't
affect me. I never bought tires from them, and I think never will.

Maybe should go back to school to study me physics, as you said...

A rarity (and a keeper). Most tire jockeys have no idea what a torque wrench
is.

I have to agree here with Edwin. At least in my area, you can't find a
shop that doesn't use an impact wrench to put the lugs back on. And I am
talking all the way from the "best" tire store, right down to Costco. The
last time I had tires done for me (I usually do them myself at work now if
the auto shop guy gives me permission) I had to demand a torque wrench be
used. I think they only agreed because the prior visit to them resulted in
two broken studs on one of my Elantra's. One of the mechanics had to drive
across the street to Sears to BUY a torque wrench. Can you believe they
didn't even HAVE one! The even funnier thing is that I went with a friend
recently to Sam's Club (like Costco) and while I was waiting for him to
shop, I was watching the tire installation department....they were actually
using a torque wrench...go figure.
