I don't think there is anything wrong with the wheels themselves. They just grabbed the wrong ones from the parts bin for the application.
I don't know the specifics on the wheels. At the time of production of my Scat Pack the 9.5"x20 wheels were the largest wheel available for a Scat Pack/Hellcat Challenger or Charger. The wide body produced later has a 11"x20 wheel but those wheels wouldn't physically fit on a non Widebody car.
