I read it is common problem, and I had issues every time balancing.The Russian-made Hakka R2 SUV tires on wife's Q5 seem to be doing just fine and didn't require any gimmicks to get them balanced. Maybe I just got lucky?
This is my second set of Nokian's in total, and I am done, never again. Not only that they are not easy to balance, but their performance envelope is very narrow.
