Explain this tire wear, please.

This is a photo of my rear right tired looking from the back.



The left edge is completely worn and you can see the fibers. Oddly enough the left treat still has a good amount left. The center is almost bald and the right side (outside) again has some left.

I can't wrap my brain around how this can even happen. This tire was always on the rear right (no tire rotation). How does that even happen? I did make sure that the tire pressure was exactly at 45 psi which is the official pressure for my car (Model S).

If anyone has an explanation, please share!

 

Camber angle isn't adjustable on Model S and tires pressure was always at the recommended level.

I also had an alignment done (by Tesla) shortly after these tires were put on.

I'm well aware of the negative camber causing inside of the tires getting worn out more. This is my 6th or 7th set of tires, I see it every time. What's so odd this time is that the inside of the tire shows less wear yet the edge, that isn't even touching the road, has so much wear that inner fabric shows. How does that even happen?

I'm thinking these tires had some issues. I got them used from a dealer.

 

The other thing that confuses me is the inner wear. I kept the tires at exactly 45 the entire time. Now maybe that might be too much. Let's assume that's too much. Wouldn't the tires show the bulging in center? It actually shows the opposite. The center is less high than the sides.

So my next guess is maybe when driving fast the center is sort of pulled out due to the fast rotation of the tire?

 

I just had new tires put on. I was able to get a better look at the tires. The non adjustable negotiate camber on the rear is definitely a major cause. It's so annoying that Tesla made it non adjustable. I also have slight torque steering (car steers to one side under hard acceleration) so I made an appointment with Tesla to have that looked at.
