2007~2015 CX-9 Rear passenger tire wearing and noise

Hello, I am having a tire noise problem on my passenger rear tire. It sounds like bearing or tire. I checked alignment and changed bearing. I can see an uneven wear on that tire. I swapped tire from front. But still the same wearing problem.

What could it be? Please help, thanks.
"Cupped" tires can making a roaring sound that sounds similar to a worn bearing.

Typically once a tire is cupped it needs to be replaced (or you can tolerate the roaring).

Thank you for the reply.
Today I went to a shop and they found AWD is not working. They said it could be that because after swapping the tire, the noise is still there. Tomorrow I'm going to Mazda to inspect it. I will update after that.
