Aero vs sport wheels

[CarterStC]

If you are basing your 10% efficiency loss claim on the Car & Driver article, they reported the 10% difference between 15" & 19" wheels, attributed mostly to weight. The difference between 18" & 19" wheels will be much less and the efficiency differential might not even be measurable by the average driver.

Effects of Upsized Wheels and Tires Tested

I removed the Aero wheels as soon as the delivery guy left my premise. I hate the Aero wheels!! Got the break calipers painted, looks amazing!

Curious, where did you get your calipers painted?

Yeah, that was not a great test. Although, I think as a percentage of total loss, the Model 3 loses more to wheels/tires than most cars because it's so efficient otherwise.
Also, the lost is measured by the EPA, and estimated here:
Tesla Model S/X/3 range at 55/60/65/70/75/80 mph

I have a P3D- that I recently upgraded from 18" to 19" wheels (swapped with a friend). 295 Wh/mile on the 18" (avg over 2500 miles), 330 Wh/mile (avg over 300 miles) so far on the 19". Obviously my numbers are higher because I use all the torques, but that's what I've seen so far. YMMV

Which tires on each set of wheels? Seems like the tires may make more of a difference than the wheels. (Sticky/grippy = less efficient)

I wanted 18" wheels, but hated the black aero covers, and didn't want to spend the extra for 19".
Another less expensive way to change the look is to dip the covers for about $50 (DIY).

AAAHHHH! I got scared for a minute, i'm ok now

I have a set of the sport 19” on, replacing the Aeros. Factory Continentals instead of the factory Michelin’s. Interestingly I find that the sports ride as well or better than the Aeros, likely because of the softer tread wear rating for Contis combined with a lower recommended tire pressure. I’ll keep the Aeros for winter.
