2004 BMW 5 SERIES User Comment / Complaint

I have dunlop sp sport tires (run flat) on my 2004 bmw 530i with 16,000 miles. the inside tread is worn beyond the tread to the point where tire threads are clearly visible throughout the inside of the tire, while the outside is almost good as new. the rear tires are completely exhausted while the front tires clearly show excess and uneven wear on the inside. the service manager states that dunlop has been replacing these tires and has not had a single refusal yet. how many thousands of defects are out there, and must a family be killed before a recall happens? the service manager stated that with another client he could poke his fingers through the tire, and that car had 6000 miles on it! i had filed a previous compiant on my 2004 bmw 530i regarding this same issue. today the service manager states that he has seen this at least 25 times, and that the issue is with the dunlop tires i have, nad not the car. i hope someone investigates this issue. please email me with any questions at: mavramidis@cox.net. i would be happy to share photos.
