[s-cars] Strange Tire Wear

[Bares, Vittorio]

Subject: 95 S6 Sedan

I've been running the same Gislave 16" tires since I bought the car 3 winters ago - they have worn evenly - with no issue.

I originally had 18" wheels on the car for summer, then moved to 17" and now am going to move back to 18" rims. All my summer tires have worn the extreme inside edge of one of the rears (they seem to alternate). I've had the car aligned - but I still get some level of tram-lining in Highway wagon ruts. Fresh lower arms and tie rods in front.

My suspicion is sub-frame, and trailing arm bushings  - although I'm not sure how to verify they are the culprit. Checking w/a crow-bar, sure they move, but do they move too much? They are supposed to move to some degree, esp w/a big lever on them...

Nothing looks destroyed or broken.

Any help before I put a fresh set of sneakers on her, and inevitably destroy 1 by the end of the summer?
