I wrote that the aerodynamic properties play a massive role, and they do, they are the dominant factor.
I did not say anything about the magnitude of actual range change.
between weight, open design, and width, open design is the biggest reason you will see a change to range.
How much change? Just look at your Tesla’s settings menu and change from 18 with aero cover to 18 without, then realize that the new design in question of the aftermarket wheels is probably somewhat more extreme so it will be a somewhat bigger loss.
it is most definitely not 50% or massive, and I never claimed it to be.
