Those tires are toast and they could be the reason for everything. I've had warranty requests denied for this kind of wear. Yes, this is an unusual pattern but I've had issues on other cars that are similar. I'd be interested in checking a few things within a few hundred miles of getting new rubber: Tire roundness and wheel truing should be proven good first. Since I had a full self-service tire shop on a military base I learned that shops just balance a wheel ONCE, apply weights as directed, and send it out the door. Turns out, balancing is more of an art. I'd balance, apply weights, shift the wheel on the chuck and balance again until it read 0 grams consistently. It can be done.
Then you have choices. Unloaded runout measurement at the hubs (calipers and disks removed) I've clamped a ball-socket test dial-indicator to the struts or caliper mounts for this. Or you can video record the wheel at speed, turning, braking, accel, looking for hop/shift that you are not feeling. A triple suction cup mount and a good action cam is all you need for that.
Could be anything from upper shock/strut mounts to half-shafts. There's always a reason.
