Brought my Ford Focus in for tire service due to unusual tire wear at
32,000 miles.  Got tires warranteed for 60K.  I replaced standard
205-R50/16 tires that came with care with Bridgestones of the same size.
When tires were removed, tech noticed wear on the inside of the tire
due to interference , apparently, with the rear suspension.  The tech
also owned a 2002 Focus which displayed similar issues with tires.  Any
expereince out there in solving the problem?  Is it mis-alignment of
tires, improper design, and placement of the strut, wobble of the tire,
a loose strut or something else.  

Car has been mostly problem free for the last year (since pruchsed new)
except for sqeaky brakes in the wet, and a coming dealer visit for a
non-operational Cruise Control.  Looking for some leads I can follow to
identify this problem quickly.  Do not want the wear problem repeated
with the new tires.  

I checked around the tires in the resting state and did not fell any
obvious interference problems.  There appeas to be about 1 1/2 inches
clearance at the point of strut contact to the axel and wheel.  At the
top, there appears to be about 3/4 of an inch from the edge of the tire
to the edge of the shielded strut.  Do things move around down there
that would cause contact when a car is turning?
