Diagnosing rear tire cupping Issues

[Jaggs]

My rear tires have some apparent feathering or cupping, and I have been trying to know what is causing it. When I bounce the car while it is parked, it does not bounce too much, and it takes bumps quite fine when driving. I also grabbed and shook the suspension parts without the wheels on to make sure they were tight and sturdy.....Despite all this, the tire wear pattern is still there!!!

Does anyone have suggestions on what could be causing this?

Did you have it aligned?

I haven't had it aligned yet, but that’s something I’m considering. I’ll look into getting an alignment check to see if that could be the issue.
