If you have after market wheel ,do you have hub centric rings ?

 

Mostly sorted out now as stated earlier. Wheel place sanded the wheel mount and it improved considerably. I then took it back for the FOURTH wheel balance and the tire shop (national chain) said their machine must have been out of calibration because wheels were still unbalanced. Now it's almost back to normal; can finally cruise over 75 without feeling like a wheel is about to roll off the car.

DNE: Wheels are OEM 19" from an M.

Thanks for yalls help.

 

Another bad tire would be my guess. I had it happen years ago and it took half a dozen trips to the shop before they replaced the entire set. Problem solved.
