Not my car. Found a wheel company claiming to fit an 11" in the rear. ADV.1 Gallery | Tesla Model S ADV10TSSL
It looks like what they consider fitting isn't that at all. Maybe its the angle, but i'm pretty sure it hangs out a bit.
When I had the wheel manufacture measure the wheel well depth, he told me it was not possible to put 11" due to rear clearance. I am pretty sure if you look closer at the car the rims would stick out .25-.5"
Fitment is all about what you want in the look. While that wheel fits notice that the rear tires are stretched on the wheels and there is a bit of wheel "poke" where the lip of the wheel sticks out from the fender. My guess is that they are running a 265/35 or 30 in the rear streatched on a 11" wide wheel. Looks damn good to me but not a super practical fitment.
