One of my tire deflates from 32 to 9-psi mysteriously every two
weeks. The other three tires are fine, they hold charge pretty well.
They're all the same brand. The tire in question have good threads
and never been punctured, other than being aged from the sun.

I remove the wheel from the car and inflate it to 40-psi. I
submerge the tire into a pool of water. No air bubbles! I pump it
to 44-psi. No air bubbles! I install it onto the car and it begins its
slow leak. I have another Honda that does this. I just give up and
buy a new tire. Would you have pump it to 50-psi? How would
you have done it differently?

TIA, Tibur Honda Accord `92 130K, Toyota Tercel 140K mi.

This used to happen on my 89 Prelude.
The tyre wasn't sealed to the rim properly.
The gap only let out air when the weight of
the car was compressing the wheel and
tyre, so the leak couldn't be replicated in
a workshop, just like you describe. The
problem was solved by refitting the tyre.

Use dish soap in water and a rag and wipe it down good. Use enough soap that
it will foam up good. Even a slow leak will cause bubbles to grow and they
will be easy to see. Wipe the soapy water everywhere (include the bead area as
other poster said, the rim itself, around the valve stem and the valve stem
itself). You will probably find something stuck in the tread you that closed
over or a leak at the bead. Could be the valve stem or even a bad casting if
these are Aluminum rims (heard of this but never seen it).

I've seen this due to two factors:
1) A puncture
2) Rim leak.

1) Sometimes the puncture is inflicted just so, so that the puncture needs
to be close to the ground, in the distorted portion of the tread that is
close to where the tread actually touches the road. If the puncture lies in
that flexed portion, the hole is forced open, causing a leak. Next time you
stop, if the puncture happens to be in a portion of the tire AWAY from the
road, there is no distortion, and therefore no leak.

2) Same thing as above can happen with a rim leak. Rim leaks can also be
affected by temperature. Colder day, lower pressure, more flexing, more
leak.

Solutions:
1) Remove tire from rim. Inspect INTERIOR for puncture. Repair if found.
2) Remove tire from rim. Sand off rust on wheel/tire mounting surface.
Clean flakes of rust off tire bead. Apply tire sealant to bead of tire or
rim. Reseat on rim.

That is a rim leak you are describing.

Try testing it in water with only 10 or 15 psi in it. Adding all that
air seals the leak up. Then putting the vehicle weight back on it works
the leak loose again.

Same thing just happened to our Cherokee with it's aluminum rims. I
took the tire into the shop and they said it isn't leaking. I had to
argue with the fool to get him to take my money for a rim leak fix he
figured I didn't need.

It hasn't leaked since.
