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.

One of the common areas to leak is the valve stem. Leave the tire
on the car, inflate to normal pressure. Then put a little bit of
spit in your mouth and wipe it over the head of the valve stem. If
a bubble forms, you will need to tighten the stem.
If you don't see one, take the tire to a tire shop and have them
check it. They will know how to check for leaks properly, and they
will have a tire tank to check it in. When I worked in a gas station,
back in the days when they were truly full service, I checked many tires,
and found some that were leaking at the stem, or at the bead, even though
the tire itself looked good. And those leaks were hard to see without
the tank.

Had the same problem on my 96 ex Accord 5sp coupe. Leak was impossible to
find, but it lost air (10 lbs every 2 weeks). Took the car to NTW, they said
it was a known problem with the OEM Michelins and put some sealant goop on
the alloy rims. This helped, losses went down to 5 lbs every 2 months. When
I replaced the OEMs with Dunlop SP40s the problem went away permenantly,
they don't lose even 1 lb in 3 months. Also, car rides and handles better
though the tires are a bit noiser at slow speed (Under 30mph).

the tire shop i go to puts 50 lbs of air in the tire so when they try to

Tibur,
Others have suggested valve stem, poor bead seal, and a hidden puncture. All
are good possibilities but allow me to suggest still another. Have you ever
run the tire with low air pressure (such as the first time it happened)? If
so, you may have destroyed the inner liner of the tire. All tires are made
from synthetic rubber compounds with different formulae but all have one
characteristic in common - they are all porus. Air will leak out through the
rubber of the tire because it is not airtight. This is over come by spraying
a thin film of hypalon based compound (usually) inside the tire. This
compound seals the tire. The only problem with this compound is that it is
not very flexible. Under severe flex situation, such as running the tire
seriously underinflated, will cause that lining to break up into small
pieces, detach itself from the inner walls of the tire, and the tire will
leak. Suggestion: dismount the tire and see if it is full of rubber debris.
If so, that is the problem and the only solution is to replace the tire.
Replace the valve stem and reseal the bead when doing this (if the inside of
the tire is clean) and your problem should be solved...
