Looking forward to some real numbers.
I see the TESLA/EPA tests posted all over. Too bad so many actually buy this crap as a solid aerodynamics test for us. As said in the Electrik article "Some of the tests were performed on a dyno machine and at 50 mph (80 km/h). In real-world conditions and at higher highway speeds, other factors like wind resistance set in and reduce the importance of the rolling resistance, which is what is accounted for in those tests." The EPA tests on a dyno. Wheel size vs rolling resistance should be relevant, but wheel aerodynamics is not tested like real life.
Not sure how many of you drive on dynos or at 50 mph, but I don't. Getting off the dyno changes the aerodynamics as you now have air moving around the car and can totally negate wheel aerodynamics. I want my range to be the best at 80 MPH.
I asked a streamliner bike owner running Speed Week one time about wheels and he said "doesn't matter, the air never hits them." He ran spoked rims at 180 MPH.
If you care, here is more info.
