I agree with Seloco. I don't believe they are the result of a normal turn / pushback. It's even gouged the tarmac!
Mind you, on a second look if the tug had got to 90° for a "tight" push , then it's not inconcievable that the bogey on the inside of the turn would scuff. That is what it looks like on the first picture which appear to show the inner (turn) bogey pictured from the front.
I hope someone hasn't made a monumental 8all5 up at the design stage.

Edited after second look at pics.
