I picked up a set of used 19" OEM wheels for my Model 3, which I'm going to use with summer tires (and keep winter tires on my original 18" wheels). The Tesla 19" wheels come with star shaped center caps (which I didn't get) but also accept the flat replacement center caps for the 18" wheels. Question: Do the star shaped center caps contribute to aerodynamic efficiency or are they shaped that way for purely stylistic purposes?

Do the 19" wheel center caps improve aero efficiency?

Purely aesthetic. I have both the 18s and the 19s, and both styles of caps—having tried both types on the 19s I can honestly write that I noticed no difference. The aero caps on the 18s however do make a difference, so I install them for road trips but use the smaller center caps and individual lug nut covers for daily duty. Good luck.
