Had independent shop align it (twice - they messed up the first time)
Happened to me too. Did a rotation at home at 10K and noted the uneven wear (inside edge). Took it to a local shop who checked it and said everything was fine (and didn't charge me). Wear continued and replaced tires at 20K and immediately had a different independent shop who specializes in Teslas do an alignment. They found a number of settings out of spec that had caused the premature and uneven wear. The new tires and the corrected alignment also resulted in significantly improved ride and handling. Lesson learned--next time I will rotate at 5K and immediately address any uneven wear with a shop who knows Teslas.
