Yea the replacement policy is OK I guess but they balance with 1 ounce weights not good for the high speed tires. I had to take my baby to the dealer to get rid of the shaking in the front end. They did repalce the defective tire they put on the front. But they had a really hard time finding the spare on my AMG. The also mounted the wrong tire when the replacement came in. They are fine for my Honda Passport but will never see my SLK again!
