Hold those horses, fellas.
The center bore on those Niche Wheels is incorrect for the Model S. The Niche wheels center bore is listed as 72.54 mm in the picture (72.60 mm on the web site). The Model S uses a center bore of 64.1 mm.
To use these wheels on a Model S will require a metal (structural) hub centering ring. NOT plastic. 72.54 mm outer diameter, 64.1 mm inner diameter.
The Model S transfers the weight of the car through the wheel hubs, through the hub bore, and to the wheel. If your wheel center bore doesn't match the hub, then the weight transfers through the lug studs instead. The lug studs are not designed to bear the weight of the Model S in the transverse (shear) direction, they are only designed to carry tension forces from the lug nuts. Thus, if your wheel center bore doesn't match the Model S hub, you need a hub centering ring, and it has to be metal to transfer the weight of the car.
Do NOT mount these wheels on a Model S without a metal hub centering ring. It's dangerous and can cause hub deformation or loss of the wheel while driving.
You can have aluminum centering rings made here:

Another issue is to make sure that the back mounting surface of these wheels has clearance for the hub attachment screw on the Tesla's wheel hub. The hub attachment screw head is not flush with the hub mounting surface on the Model S, so the wheel has to have a "pocket" for clearance on the mounting surface. I cannot find any pictures of the mounting surface of the Essen M146 wheel, so I can't tell for sure if the pocket exists.
If the pocket doesn't exist, you cannot mount these wheels on the Model S, as the wheel will not sit flush on the hub.
