Have a front tire on my 2002 Nissan Altima, fill up the air to 30psi, drive
it for several days, no problem. But on the weekend if I don't drive it and
just leave it, by Sunday afternoon the tire will be deflated to about 12psi.
I fill it to 30psi again, drive it for another week, no significant pressure
loss, and then leave it for another day, goes to 10psi. Obviously it's some
kind of slow leak? Took it to Tire Kingdom, Good Year, Firestones and none
of them were able to locate any leaks, Good Year told me they put it under
water and saw no bubbles.

Any idea, this is like the forth week in a row it did this. There has to be
some reason the tire deflates on weekends only.

It's driving me nuts.

id take it somewhere and ask them to remount the tire and clean the rim edge
while there at it, ive had several tires in the past doing what you say is
happening and remounting it fixed it

Do you park it somewhere different at the weekends? If so, is it on a slope
or camber putting more weight on the leaky tyre?

No change of location on weekends.

ay sound obvious, but since it happens only on the weekends, and the
Goodyear shop checked the tire and found no problem, is there a chance that
someone is "pranking" you? A kid in the area may be letting the air out of
that tire as a prank...

If you check it frequently over the weekend, to see if the loss is gradual
or sudden, this should help to narrow it down. If there is a sidewall,
valve or bead leak, the loss will be gradual. If the loss is sudden, it
indicates something else.

I had a similar experience once...during the week, the side mirrors on my
car would stay where I would set them. but if the car sat during the
weekend, the mirrors would be off...
It drove me crazy until I started closely watching the vehicle, and found
that the person who parks next to me had two kids, and on the weekend they
would mess with the mirrors when getting in or out of their van. After
speaking with the parents, the problem stopped.

I don't think this is likely. When I do drive it on weekends, it does not
deflat. It seems to do it overnight.

Could it be a neighbor kid playing a trick?
