The rim bead is normally cleaned by the tire installer. Aluminum does build
a small oxide layer, then stops. OP is probably referring to bent rims not
readily apparent to the naked eye. And, yes, its true. Such can leak air
at a very slow rate. If present, replace the offending wheel/rim, not all
of them.

She says "tires" so I doubt that all four are bent. But I could be wrong.

Ford had a problem with porous cast Aluminum wheels. The fix was to paint
the inside with epoxy based paint.

Well you are suppose to check your Air at least monthly! You may have a
leaking RIM, or a leaking tire, but 7 pounds in MONTHS doesn't seem to
really be a problem to me. If your getting new tires soon, and rims are
also a option for you, maybe you want to Upgrade to something better. A
little larger wheel, Larger tire maybe. Aluminum from Steal. Whatever.
Trying to find such a slow leak as that is virtually impossible.

One front, and one back have slow leaks. Also, they seem to stop leaking at
23 pounds. I can fill them back up like I did today, and give it 4-5 weeks
and back down to 23 pounds.

To me it sounds like the rim and tire have either dirt or corrosion at the
bead. When the tire gets down to 23 lbs. pressure there isn't enough
pressure to push air past the poorly seated tire.

air them up to about 50 psi, and dunk them in a water tank to find the
leak and then fix it. talking about it wont fix them.......

"a months time" = 1 month.

My mechanic has checked them, cannot find a leak.

Gee, thanks.

Read your owners manual, mine says check your tire pressure once a month or
more.

I had that happen due to air leaking around the base of the rubber
valve stem.

I help maintain a fleet of vehicles that have more steels wheels than
alloy wheels. The alloy wheels ALWAYS give us more bead leak trouble
than steel wheels. Corrosion is more likely on alloy wheels than rust
on steel wheels concerning the bead. Generaly speaking, this occurs on
vehicles 5 years or older.

Many bead leaks can only be detected once you air them to 50 psi or
more if soap testing or putting the tire/wheel under water.
