DUNLOP SP SPORT SIGNATURE SIDEWALL SEPARATION. RISK OF SERIOUS PERSONAL INJURY AND/OR VEHICLE DAMAGE COULD RESULT. THIS APPEARS TO BE A COMMON OCCURRENCE FOR THIS MODEL OF TIRE ON WEB SITES SUCH AS: HTTP://WWW.VEHICLETIRE.COM/COMPLAINT/DUNLOP/SP+SPORT+SIGNATURE. *TR

THE VEHICLE WAS USED UNDER NORMAL DRIVING CONDITIONS. THE TREAD OF THE TIRE BEGAN DE-LAMINATING FROM THE TIRE AFTER 40K MILES. FORTUNATELY THE CAR WAS IN FOR SERVICE AND THE MECHANIC FOUND THE DEFECTIVE TIRES BEFORE THEY CAME APART WHILE DRIVING. ALL 4 TIRES WERE REPLACED, BUT THE OLD TIRES REMAIN IN MY POSSESSION. *TR

NOTICED SIDEWALL CRACKS RANGING FROM ONE TO FIVE INCHES ON THREE OF FOUR TIRES (THE REMAINING ONE TIRE WAS A REPLACEMENT FOR A PREVIOUS TIRE WITH SIDEWALL FAILURE. ONE TIRE HAS CONSISTENTLY BEEN A PROBLEM WITH LOSING AIR. TIRE WAS RESET WITH BEAD SEAL PREVIOUSLY, STILL SEEMED TO BE LOSING AIR, AND THIS IS THE TIRE WITH THE LONGEST SIDEWALL CRACK. *TR

I HAVE PHOTOS AVAILABLE OF THE TIRE IN QUESTION. THERE ARE 3 SEPARATE PIECES: THE COMPLETE (INTACT TREAD), THE INSIDE SIDEWALL AND THE OUTSIDE SIDEWALL. THE TIRE CAME APART WHILE DRIVING BACK FROM VISITING RELATIVES AFTER THE HOLIDAYS. I WAS TRAVELING ABOUT 60 MILES PER HOUR WHEN THE LEFT REAR TIRE EFFECTIVELY CAME APART. THE CAR STARTED FISHTAILING AND I CAME VERY CLOSE TO RUNNING OFF THE ROAD WITH THE POSSIBILITY OF ROLLING OVER. IT WAS A VERY SCARY SITUATION. I FEEL THAT THIS TIRE AND PROBABLY THE OTHER 3 TIRES HAVE A MANUFACTURING DEFECT. GOODYEAR/DUNLOP WANTED THE TIRES TO BE INSPECTED BY ONE OF THEIR DEALERS AND THEN CONFISCATED AND DESTROYED. I BELIEVE THAT THE WAY THE TIRE IN QUESTION EFFECTIVELY DISINTEGRATED CONSTITUTES A SERIOUS MANUFACTURING PROBLEM. I CURRENTLY HAVE ALL FOUR TIRES STORED IN MY GARAGE. IF AT ALL POSSIBLE, I AM ASKING FOR YOU TO INSPECT THESE TIRES SO IT CAN BE DETERMINED ACCURATELY WHETHER OR NOT THEY PRESENT AN ONGOING SAFETY PROBLEM. I WOULD NOT WANT ANYONE ELSE EXPERIENCE THE TRAUMATIC EXPERIENCE I HAD TO ENDURE. PLEASE LET ME KNOW IF YOU CAN HELP ME WITH THIS MATTER. *TR

TREAD HAS SEPARATED FROM TIRE CARCASS ON ONE TIRE, IMMINENT ON OTHER THREE TIRES ACCORDING TO DEALER. SUSPECT DEFECTIVE ADHESIVE OR APPLICATION DURING MANUFACTURE OF THE TIRE. *TR
