I had this on my M3P and did not address it quickly enough so probably knocked many thousands of kms off the life of my tyres. They still lasted almost 50000km but I had kevlar and steel sticking out the inside edge of all four tyres.
It seems that Teslas can end up with significant significant negative camber which leads to this uneven wear patterns. While regular wheel alignments are critical to tyre life and energy efficiency for any vehicle, perhaps this is more critical for Teslas. So, even though they are more expensive than alignments on ICE vehicles because of all the covers that have to be removed and replaced, it is worth doing it every 10000km or so, with rotations every 5000km or so (which can easily be done at home) making sure to keep a close eye on the tread and jumping on any sign of uneven wear.
As to replacing your tyres, it looks like the Michelin e-Primacy is probably the best option out there. Low resistance, quiet, decent life, good handling. Not cheap though.
