Is it possible the trim ring is touching the sidewall of tire and the rotation is causing the ring to move? Also possible the clips on the back of the trim rings have seen better days?
I don't think I would strike any arc on the wheel itself until you figure out what is causing the movement. Maybe a bead of epoxy or silicone on the wheel instead.
Maybe these posts need to go some place else to avoid hijacking this thread.
