Either you posted the wrong front tire size or that guy has wrong front tire fitment on the fronts.

Front tires should be 275/40/20. Style 214 is an E70 style so I'm guessing they would fit the E70 no problems, E53's probably need a hub centric ring to go from 74.1 - 72.56 center bore.

Take a pic of the letterings on the inside of the spokes, that will tell you whether OE or replicas. However, like others have said, price is way low for an OE set.
