    I really would like to know the bolt pattern and offset for the Tesla Model S. Hopefully that information will be released soon. I am a wheel guy and I have a set of Advans that I would love to throw on the Tesla. They are lightweight 20" wheels that have a gorgeous concave face that I think would compliment the S very well.

    Not to mention what's actually measured (and arguably what's actually meaningful) is CdA. A has to be divided out to get Cd, but different people have different ways of defining A.

    Tested some simple disk wheel covers. They're not too pretty but reduce energy consumption about a 6.5% at 60 mph. I was cautious not to use the brakes and over heat the rotors as they have no vents at all. I will need to do some more extensive testing speed vs energy consumption and possibly measure rotor temperatures with & without covers after a stop.

    where did you get the wheel covers and how do they attach to the wheels?

    Very interested in this as if they can be added or removed easily might be something to place in the trunk or frunk for use only on long road trips. Any comments on this possibility would be welcomed.

    Cheers.

    Try painting the covers in very dark matte gray, similar to dusty rubber. They/car may end up looking very wicked :D
    To improve cooling: try adding half-circle holes around the perimeter, an inch in diameter and an inch apart. Paint the wheels in black, to make the holes hard to see.

    Maybe painting the Tesla logo radiating out from the center like spokes? Looks good.

    Great work, I too would like details. Definitely test before adding any holes, you may not need them.

    I'd like to know where you got them as well, and maybe some pictures of the wheel-facing side to see the attachment points.

    Nice work. It would be cool to have them as others mentioned for long distance runs to maximize range. Please keep us informed of your discoveries.

    They are held on by 5 5/16-18 screws. I didn't like drilling into the alloy wheels as this would weaken them and cause a stress riser. They are threaded into fastener mount cable ties which are attached to the 19" rim spokes. The issue with this setup is centering the covers I was very careful in the spacing to center them and prevent imbalance.

    JRP you are right they are 21" pie pans, however 21" pans are not exactly 21" in outside diameter they are about 21.5" which puts them just outside the rim lip, which I had hoped to use to center the covers. A 21" disk would be optimal, I know Mooneyes will custom make them, but they would be a bit more than $15 ea.

    Regarding venting the wheels, I noticed that the car covers sold by Tesla have mesh over the driver side front wheel. Not sure if the passenger side is the same.

    That is such a dope idea. All black would make the car look so awesome. I'm going to have to try this!

    I wonder if you could take the pans to a machine shop or fabricating shop and have them cut down, probably wouldn't cost much. Clever use of the zip ties, I was wondering about using a J bolt that would hook behind the spokes and then tighten it down with a nut on the pan face. Then you wouldn't have to cut the zip ties off each time.
