2004 BMW X5 Wheels Problems

I BOUGHT 4 RUN-FLAT BRIDGESTONE TIRES FROM A BMW DEALERSHIP: DUELER H/L 400 [36110427162] ON JUNE 21, 2017 WITH MY SUV MILEAGE OF 169,318. YESTERDAY, 1/15/2018, I FOUND OUT MY TWO REAR TIRES WERE ALMOST BALD AFTER DRIVEN 10,384 MILES DUE TO SUMMER ROAD TRIP. SEVERAL TIMES THESE PAST FEW DAYS I FELT THE SUV WAS SLIPPING AND SLIDING EVEN THOUGHT NO ICE AROUND. THE TWO REAR TIRES HAVE MARKINGS OF DOT H491 DJE0716 AND DOT H491 DJE0216]. THE FRONT TWO TIRES [DOT H491 DJE4015 AND DOT H491 DJE3160] LOOK NEW COMPARED TO REAR - PLEASE SEE IMAGES.

THE VEHICLE STARTED SMOKING FROM UNDER THE HOOD WHILE DRIVING IN TOWN TO THE POST OFFICE. UPON PARKING THE VEHICLE AT THE POST OFFICE, IT CAUGHT FIRE UNDER THE HOOD AND THE FIRE DEPT. HAD TO BE CALLED TO FORCE OPEN THE HOOD TO PUT OUT THE FIRE. THE ENTIRE FRONT OF THE VEHICLE WAS DAMAGED IN FRONT OF THE FIRE WALL. THE USPS MOVED EMPLOYEES/CUSTOMERS TO THE REAR OF THE BUILDING FOR PRECAUTION OF EXPLOSION AND SMOKE INHALATION OF THE BURNING PLASTIC, RUBBER AND RELATED PARTS. IT WAS FORTUNATE I COULD QUICKLY PARK RATHER THAN BEING ON THE HIGHWAY.
