I remember one person posted the lug nut holes were mis-drilled on a wheel causing an out of round situation that a wheel balancer will not detect since it is using the center hole on the wheel to mount to the machine. I don't remember if the issue was aftermarket or stock wheel.I am not sure I understand what you are saying.
They put the wheels themselves on the machine to check for balance and any run out. Then the tires were mounted onto the wheels and balanced. Then they did the road force balancing. All turned out well. How would you find a bad wheel/rim otherwise?
The vibration hasn't changed one bit through 3 sets of tires.
