I took delivery on Tuesday evening. It is a Performance Sig equipped with 21" tires. I live in the Northeast and needed a 19" option for winter tires, but I want to maintain the look of the 21" wheels. I think I have come up with a pretty good solution that I wanted to share with the group.
Below are pictures of 19" Rial Lugano wheels I acquired through Tunershop.com. The wheels are 19" Rial Lugano 5x120ET32 and cost $1388 for a set of 4. Shipping is free. I had them shipped to the local Tesla service center, which installed TPMS and mounted the Pirelli winter tires. Note that Tesla cannot deliver your car with anything but OEM parts, so I am going to have a local tire shop mount them, probably this weekend.
If we can find someone to supply a Tesla center cap, they will be virtually indistinguishable from the factory wheels.
I think they are a really good match, let me know what you think.
I will post more pictures after they are on the car.
