Thumbs up Bad rear tires wear need info

I noticed uneven wear on my rear tires
Had the allignment checked and they said everything is ok
I run 285 35 r18 on 10 inch wheels, I wonder if normal adjustments should be used?
Here is a picture of the wear pattern

The alignment spec is a very broad range, what were the actual measurements? If you are at or near max camber (better for handling btw), you will get some asymmetric wear. If you are at or near max spec toe (bad for everything IMO), wear rate will be greatly accelerated.

Within stock specs, I generally recommend maximum camber and minimum toe. This gives decent tire life and good handling. If you're willing to sacrifice handling, going with minimal camber (negative ~0.5degrees) will get you ~10-15% greater tire life vs. max camber (generally negative ~1.3 front, ~2.2 rear).

Too much rear toe is my guess...they probably maxed it out. Dealership alignment?

How low is your car? Got a side shot? How many miles are we talking also? I didn't think the wear was that bad, but my alignments are typically on the out of spec side of things.

Standard height,
About 10,000 miles
The diagonal inside erosion is the thing I don't like
