I've had it confirmed by a tyre guy that its def not wheel spinning/driting/etc. The wear is consistent to the middle tread, nowhere else.
Its only happened on this one wheel, not a single mark on any of the others. They've all done about 6k miles since they were fitted, and I got the wheel/tyre package off a brand new Demo from a dealership, and they'd done barely 500 miles.
My brother drives the car with the respect it deserves, he knows that not only I would, but my 6'6" stocky boyf would come down on him like a tonne of bricks if he didn't.
