Stopped by a Tesla store with my family today while on a road trip, and a salesperson I've known for a long time told me that the 21" wheels will have a range cost of around 5% vs. standard 19" wheels. That was news to me. I apologize if this had been said before--I was under the impression from previous discussions here that we would expect the range to be about the same vs. anything but the aero wheels. This means the aero vs. 21" wheel difference is even larger. He also claimed the 21" wheels offer handling benefits. Anyone else heard about this range drawback to 21" wheels? If not, I'll try and confirm with Tesla via email. Trying to make final decisions as it sounds like my order will be coming up very soon: They told me they took the order for SSL #70 a few days ago.
