Hi,
Just wondered what if topping up with ordinary air to a nitrogn filled
tires. What would happen? Good, bad or any harm?

not a problem. the question is, why did you bother with nitrogen in the
first place?

Hi,
Wife had new tires put on at Costco and they only use nitrogen.
When I took the car to a lube joint for oil change they are not gonna
bother with tire pressure check because of nitrogen(green valve cap).

just do it yourself and fill at the next gas station.

there's a small advantage to nitrogen related to partial pressures, but
that only works on initial fill. after that, you may as well just
maintain pressure with free/cheaper air. you'll certainly never know
any difference driving around.

Since air is mostly nitrogen anyway, you will just end up with less
nitrogen in the mix, which was probably not 100% nitrogen to begin with,
because the tires would have had some air in them before inflation.

Indeed.

Of what advantage is 85% nitrogen over the 78% in regular air?

Google "atmosphere composition"

it wastes the oney you spent to get a nitrogen fill.

less O2 for the tires to absorb?
(internal pressure forcing more absorbtion that outside air.)

that's why you shouldn't waste your money in the first place!

tires "absorb" [diffuse] oxygen from atmosphere anyway. if the tire is
100% nitrogen, oxygen will still diffuse in - partial pressures.

the only technical advantage to nitrogen is on the extreme performance
end of the spectrum where you may want to minimize oxygen for fire
protection, or water vapor [always present in air] for icing. like
aerospace.

if you allow any of the nitrogen to escape, thousands could be killed.
