A cheapie Harbor Freight wire wheel when first fitted gave excessive vibration. Checked it on a simple device made originally for model propeller balancing and found very significant out-of-balance. Made some additional bore slugs for hub to allow use of balancer and after some checking and adding couple of sheet metal screws to wheel outermost hub metal, achieved a near balance - result? - pretty smooth running. Certainly worth checking any wire wheel I think and balancing not too difficult. Remember eye protection in use, as sheet metal screw fitting can loosen a few bristles.
