I don't have an answer just questions that may help you.

I hope they are torquing lug nuts to spec.

What air pressure are you keeping the tires at?

Could it be a bushing, body mount, engine or transmission mount that needs to be replaced? I had to replace a poly transmission mount because as it aged the vibration got worse.

Could the vibration be coming from the body due to stiffness, I have heard of newer GM trucks do this because the body's are so stiff.

Could it still be a tire problem and worth a shot asking if you could switch to a different brand? And or take your wheels completly off the car and install wheels from another challenger on the lot and take for a test drive?
