Got it. And youre right it looks like only the toe can be adjusted for Teslas in general.You're on the right track, but I will say the negative camber, unless it's really aggressive (-2 degrees or more) won't wear the inside edge of the tire. If you tried to pull the camber out (which I don't even know if the model 3 suspension has the adjustability to do) you're going to hurt how the car handles in turns. The toe is likely the issue. For example, I have a modified 911 Turbo with about 1.5 degrees of negative camber dialed in and I don't have any inner edge wear at all. but I also added adjustable toe arms to pull the toe out as camber is added.
Thanks again!
