How to identify between Genuine and Replica wheels?

[Ings-net]

Hello there, does anyone knows how to identify between a wheel (e.g. Rays, SSR...etc) is either Genuine or Replica ? cause sometimes some dealer might trying to cheat the customers who unable to identify it is either Real or Fake. And sometimes wheels bid from internet might be fake as well. I'm pretty worry bout these issues while i'm planning to buy wheels. Hope u guys can give me some hints, suggestion about this ^.^ thanks you
