Stick on weights are notorious for this, especially when being used on the outside of the rims. The machine does not account for the extra weight beyond the point where you are sticking on the weights when calculating the "required" amount. 75% of the time, less weight is required than the machine states to balance the tire, and adding the exact amount the machine states leads you into a vicious cycle.
I have used some basic and Advanced balancing machine and I have sent back and rejected GoodYear, BF G, Continental, and other brands as defects. Sure I can get the machine to read Zero-Zero but that won't make the steering wheel not oscillate or the tire NOT bounce.
Where I work now we have a Road Force Variance machine that will allow for the weight locations (even behind wheel spokes for hidden weights allowing for split weighting but not counter balanced) and is pretty dang close if you do your job setting it up. When I worked at Sears with a basic Coats balancer it was a guessing/intuition learning curve on using sticky weight that I got darn good at.
But Zero-Zero weights does not mean it will work properly. If it is egg shaped or has excess lateral runout your done.
Recently sent back a set of $800 GoodYears for an Expedition that had either excessive lateral or radial runout on ALL 4 Tires and it was some of their new stuff. The guy insisted that is what he wanted so we got a second set that was OK.
