2008 BMW 5 SERIES Tires Problems

TL* THE CONTACT OWNS A 2008 BMW 535I WITH MICHELIN PILOT SPORT PS2 RUN FLAT TIRES, SIZE 275/35/R18. THE CONTACT STATED THAT THE CENTER OF BOTH REAR TIRES WAS WORN TO THE POINT WHERE THE CHORD WAS VISIBLE. THERE WERE NO FAILURES WITH THE FRONT TIRES. THE ALIGNMENT WAS TESTED BUT NO FAILURES WERE FOUND. THERE WERE NO REPAIRS TO THE VEHICLE. THE DOT NUMBER WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 45,000.

I HAD PURCHASED A NEW BMW WITH DUNLOP TIRES ON. MY TIRES ARE USED LESS THAN 1 YEAR AND USED ONLY FOR 34,000 KM (21,200 MILES) BUT THERE ARE NO THREADS LEFT ON THE TIRES. I HAVE CONTACTED DUNLOPS CUSTOMER SERVICE IN AMERICA AND CONTACTED THEIR OFFICE IN TURKEY AND THEY HAVE SENT AN EXPERT TO CHECK THE TIRES. THEY CLAIM THAT THE AIR PRESSURE WAS LOW SO THE TIRES WERE WORN QUICKLY. THAT IS RIDICULOUS BECAUSE MY CAR IS NEW AND IT WAS CHECKED BY AUTHORIZED BMW SERVICE FOR ROUTINE CHECKS SEVERAL TIMES AND I HAVE A REPORT FROM AUTHORIZED BMW SERVICE THAT TIRE PRESSURE WAS NORMAL. ON THE OTHER HAND THIS CAR HAS TIRE PRESSURE SENSORS AND THERE WERE NEVER LOW PRESSURE WARNING. I HAVE MADE A RESEARCH ON THE WEB AND FOUND OUT THAT DUNLOP TIRES HAD SO MANY CUSTOMER COMPLAINTS SIMILAR TO MINE AND HIGH COURT...
