I have a P85+ with 730 miles now. Delivery two weeks ago. Decided to go to Firestone and get alignment checked given the variability in tire wear reports. My rear toe was out of spec a little. Range is 0.10 to 0.30. Mine was 0.46 Left and 0.08 Right. Total Toe was in spec 0.53 (range is 0.20-0.60), but the mechanic explained that it means my car was crabbing down the road a little when I was going straight (rear tires parallel to each other, but not pointed straight forward with the fronts), and that scrubs the tires a little. He easily got everything perfect. 0.22 L, 0.21 R, 0.44 Total
I called the Service Center in Denver to ask if alignment is included in the Annual service, and he said NO. Tire rotation is included, alignment is not. Therefore I got the LifeTime alignment at Firestone for less than the cost of one tire (under $200). I can take it in every 6 months and have them recheck it. I think it is well worth it and something everyone should do with tires that can wear this fast.
He did need this information to figure out how to do the alignment on the rear, given to me by Lolachampcar:
One hint would be to let any non-Tesla shop know that toe can be done in the rear without removing any floor panels. A ratchet, extension and socket allows for loosening and tightening the toe adjuster nut while a simple end wrench allows you to hold the bolt from rotating on the other side(a bit of a PITA). The ratchet handle will be just aft of the rear of the lower a-arm where there is room to get your hand on it.
Now that I think about it, I wish I had taken a picture of the bolt they have to turn....
