Harry, it's best to have wheels balanced at a MB dealer ... the Service Department uses 2-piece MB balance weights ... at least on the wheels for our 1991 and 1992 300CE's and our 1998 E320. Newer wheels with the smooth edges may require stick-on weights, but I would expect the dealer techs to clean the wheel, as required, so the balance weights stay on under normal driving conditions. The MB dealer may charge a bit more than the local tire store, but the job will be done correctly ... and the balance weights will be appropriate for a MB wheel. It's the little details that distinguish a MB enthusiast from a person who merely drives a MB.
