RE: bearings or bad tire?
Not sure if this is the same problem, but when I had new tires
installed on my urQ I had to go back 3 times to get them balanced
properly. It turns out the car is extremely sensitive to balance
they had to set their machine to its most sensitive position.

I have the same symptoms on my 85 q Coupe. I had it with the previous
wheels, too. Still couldn't cure it and would be greatful if anyone
suggest a good move.
