The fact that you don't have stickers doesn't mean that they are fake. On the other hand having them doesn't mean they are real. The wheels could have been replaced, repainted and / or repaired. If the car was sold by a dealer most probably it is CPO and most probably wheels are BMW, not neccessaraly originals. It's really tough to say if those were the original wheels of the car, even though the car is spec with ZCP wheels.
