I have problems getting my Stern ST-1s balanced correctly. They seem to be remarkably difficult to balance. It took two different places and 5 tries to get them acceptable... and then last week I rotated my tires and told them to go ahead and balance them, and sure enough now there's a shimmy again.
The weird thing is I even stood there and watched them balance them, and the machine said they were good (at least as far as I could tell, I am by no means checked out on a wheel balancer). Guess I should have left well enough alone
