I use
Big O Tires, they have a six month warranty, so you can reschedule for free,
something to consider if you do a lot of driving, or if one day you hit a big pothole and worry about it.
They give me a copy of the Tesla recommended procedure documents, which mention to put the car in Neutral.
At the time there was no Car Wash mode, so one of the technique was to buckle up before seatting the driver seat belt,
put in Neutral, and exit by the passenger door. You could aslo use the Towing mode, but this stops after 20 minutes.
Recommended also is to put some weight on the front seats, but they didn't do it.
In fact my car alignment only needed to adjust the Toe-In who were just over the limit.
