No one seemed interested. Here are the unpainted ones:


I've painted them with flat-black to match the tires. But this led to another challenge at night:



A 1/16" shallow cup drilled in the stud ends filled with clear epoxy and phosphorescent powder. This makes changing a black tire and cover at night possible.

The modified pizza pans are held to the wheels with black, plastic, zip ties.

As for aerodynamics and videos, my next interest is cleaning up the front bumper:
  • Confirmal surface to left and right of cooling air inlet.
  • Conformal cover for left and right cheek inlets.

In the future, I may investigate:
  • Inside wheel covers
  • Fully reclining passenger seat (aka., hotel Tesla)
  • Thermal insulating bottom of battery pack
  • Vortex generators vs rear spoiler
  • Underbody 'air dams', front and side
  • Removable, exterior mirrors and/or aero tricks
  • Rear wheel well covers
