I saw a photo in the last few months of a car tyre with very similar 'all around the side wall' damage. Memory suggests that it was extremely similar. Where I saw it I know not (may come back). More likely (agh) Facebook than not. I suggested that it appeared to be from 'enemy action' and others were asserting it's likely being due to happenstance. I think being driven flat was one suggestion - whether based on any knowledge I know not.
