Would you rock solid/flat/smooth wheels for more range?

Hell No even if it gave me an extra 100 miles of range. I also think these also look terrible.

Actually? I thought these wheels were beautiful. I misread the intent of this thread at first. No, I wouldn't go with pizza pie hubcaps or Volkswagen/Porsche domed wheel covers. But no, I also wouldn't go for extreme low resistance with incredibly narrow 165 tires inflated to 60 PSI and worn down to bald spots with no tread either.

Does anyone have real world numbers on the effect on range?

I do. I had custom made solid disks on my Model for about 5000 miles. They make a significant difference. The effect is entire aerodynamic, so the faster you go, the more the positive effectiveness. On a road trip from Los Angeles to Minneapolis it gave me about 8-9% better range/lower energy consumption and thus saved me time on charging as well. In city driving (at lower speeds) the effect is much less.

I actually got a lot of positive feedback from people about the look. I really wish Tesla would offer simple attachable disks or true disk rims for those who want it. It's funny for people are so concerns about range loss and are willing to pay a lot of money for a slightly larger battery, but this solution would give you more range for a very small cost.

8-9% is huge considering a newer model with a range of 300+ miles that's an additional 24 miles. For me that's an entire one way trip to work.

3% I might pass on but 8-9% and now you have my attention.

I love the looks of your car.
IIRC you mentioned the biggest problem was noise from disks vibrating?

I was able to get that under control with some foam, but not completely. The attachment of the disk itself is a problem in many ways that's why I ended up taking them off. But the concept works really well. Someone just needs to make it a real product, ideally a true closed (or almost closed) disk rim.
 
Too bad they don't make moonie hubcaps in 19 inch. All I could find is 17 inch and smaller.

Smaller wheels would increase range as well. I do so hope that Model 3 and Y have much smaller calipers so I can run smaller wheels. I'd run 15" if I could but I know that 17" or 18" will be more likely.

I actually had 15" Honda EV wheels machined so the center bore would fit on a Leaf. Switching from heavier 16" wheels to lighter 15" wheels with closed face increased the range a ton (think double digit percentage) because of lighter wheels, lighter tires, narrower tires, better aero and so on.

The lack of common aero wheel options and the insanely large calipers are one of the biggest reasons I'll avoid getting a CPO S instead of a 3 or Y. Though AP2 HW and the HEPA filter are up there on my nice to have list.
