I think they have to try pretty hard to mess up an alignment with modern EPS. It masks alignment errors to some extent and road camber.there is nothing special about alignment for tesla vehicles. if you dont live in a capital city you have to go to the same tyre place other plebs have to go to (i.e. jax tires, goodyear etc).
I have never seen them mess up an alignment. when i let go off my steering wheel the car keeps just going straight forever.
My car tracks straight, so when I get jax to fit new tyres, I am not going to touch the alignment. Will likely go with the 235/45 ZR18 (98Y) PILOT SPORT simply because they area a known quantity. You guys have convinced me not to chase acoustic linings. If there is an alternative tyre that is noticeably quieter I will consider it, but there doesn't seem to be one.
