Wheel bearing or...stone behind disk?

[Dis86]

High pitched squeal. Can hear it on passenger side only. Doesn't start initially but builds after driving for a short while. Disappears when turning left.
'pulses' at lower speeds.

Bmw i3s.

I've had a stone between them before. Probably not the best idea, but I just launched it forward and in reverse, worked.

Or I think it was a stone, because it stopped after this.

Just keep turning left then.

Most likely a stone if it's high pitched squeal

Your brake pads aren't low are they? Could be the wear indicator rubbing on the disc?
