Make sure the info is correct for the vehicle you have, This should all be in the DT database and usually what happens is they just insert the wrong vehicle info. Firstly, make sure that's corrected. Secondly if you have a setup like this, tell the person and confirm. I've run fleet vehicles and changed more tires than someone could imagine from 8" all the way up to 24.5" looking at a 1/2" width difference isn't easy. but DT uses Hunter Engineering balancers, who I've worked for, and those usually require the width of tire to be checked with the machine and the tech should have figured it out then. What probably happened was they saw one was 9 or 9.5 and they assumed the others were and didn't change the settings.
However, on all those notes, it could have happened to anyone. Tesla obviously knows that because the techs were specifically trained on it. DT and any other shop has to be able to service every vehicle ever made.
The was a DT where a guy took his Ford GT to, it was the same tech that did his tires every time because he taught the guy to do it and the guy knew. If someone doesn't know and the data doesn't say otherwise, they don't know to ask.
