This is the point that never gets across. The manufacturers made no attempt to balance drums and hubs for many years. Show me the drillings in your drums.
I have been balancing my tire, wheel and hub assemblies for many years. I can static balance them in my tool & die shop, or spin balance them on the trailer with my Alemite Electronic Wheel Balancer.
The point that I failed to make was that an unbalanced tire can be better or worse depending on how its mounted relative to the heavy spots.
If you can't find the drill marks, I guess I'm still on for dinner?
