Rear tire separation, IMO.

If tires have been checked and balanced, google "scuttle shake" sometimes called "cowl shake" related to rag top autos. (Possible!)

Internal tire plys are, well seperated. Tire out of round, worse at higher speed. We just offering a best guess, it's all we can do online! Now , if we could take it for a test drive, that's a different story! So that may be what you need to do is have a mechanic drive it.
