Thank you. Where did you get the photos?
The key word here is "might". Someone elsewhere posted a photoshop of these guys in a dark color. They didn't look too bad, but as they are now, I think they are pretty hideous.
Given the sheer beauty of this car, these 19's really detract from that. Can I "live" with them? Certainly. Will I be frustrated every time I look at them? Probably. I will probably get identical sized and prettier wheels for daily use, move the stock tires to those, then put winter tires on these originals. I should be getting my new MSLR just prior to ski season anyway.
I think they are coming soon. Many people with 19's were given EDDs of August, though it seems almost everyone went blank today. Given that it is a Sunday, I would hold off for a couple of days before making any assumptions. At the same time, assumptions is what we do best here, especially since we here nothing from Tesla. My guess is that 19's are just on order and awaiting arrival. Probably a delay in their vendor. It would be no big deal if they would just say that.
