At 55K the "shoulder wear" (post #11) in the picture seems normal and unavoidable.
Your rotations kept things even-Steven but the scrubbing off of rubber during turning is what I think is in that picture.
I rotate too all my old tires looked like that as they neared the end of their lives.
I read that alignments (and balancing) hold longer than people think.
Sure, inspect for worn parts but otherwise...if it ain't broke.
