Went to my local Les Schwab yesterday regarding tire noise on the rear.
They tell me the pass. side rear tire is cupping on the inside edge. I
asked what could cause this and the answer was "bad strut". I was
wondering if this is true and if under inflation or something else could
cause this? The other tires seem to be OK. The tires are Falken Bias
Ply which I think may have been a mistake; but, they seem to have good
tread wear.
If the rear struts need replaced can it be done just removing the strut
shaft nut, or does the plate holding the strut shaft also have to be
removed? The rear of the car is full of stereo gear so I can't get the
side panels off easily; but, I could cut an access hole to get the strut
shaft nut off.

You have bad alignment. A bad strut, spring, or tie rod end could
easily cause this bad alignment. If you still have the original struts
or outer tie rod ends, replace them, and then get new tires and an
alignment.

Hmmmmm....
Had an alignment when the tires were installed. Tie rods on the rear
wheels of a front wheel drive? Haven't heard of that, guess I'll have
to check. I do remember the tire on that side of the car was under
inflated by ~10psi. I didn't discover it until after I had driven
several hundered miles, I went on a long trip the day after they were
installed, but, that was several thousands of miles ago.

FWIW... bad alignment will not cup a tire..... A bad shock or strut, out of
balance or a tire just plain gone bad CAN cup a tire.
I do have a concern with the original poster saying his tires are bias
ply.... While there *may* be some suppliers for reproduction type tires, I
doubt that any of the "newer" players in tire supply bother with a bias ply
construction and I seriously doub that any tire shop would have such a tire
in an appropriate size in stock (since a bias ply would be something like a
6.50 - 15 or maybe even a G78 - 14).
Under or over inflation will have it's own particular wear
characteristics.... but, an underinflated tire might also have suffered
internal damage from overheating.
What we do know..... if we replace all the parts, at least one of them will
be the faulty one.
If we are to give advice, we should consider it's content carefully.

Thanks Jim,
I thought I heard the installer say the tires were bias ply when I asked
if they were steel belted radials and he said "no". Maybe he said nylon
belted? How do I check? I know they are the modern size ratings.

Thanks for the link Joe. I notice the pictures show a cupped tire with
cups across the center. My tire place says mine is cupped on the inside
edge only. Is this possible?

Yup, entirely possible,
In the realm of vehicles virtually everything is possible, one learns
this as time passes (6 defective brand new cruise control modules in
a row for the same car taught me that).
As did the Caravan who's rubber rad supports would soften when hot
allowing the rad to drop onto the ignition wire causing a hot running
stall out, but disappearing during 90% of the driving.
Have your suspension and alignment checked, buy some good new tires.
Or... if it's an older beater, say "wow, neat" keep driving, then put
some other cheapies on when these wear out. :-)
