MY WIFE AND I BOTH OWN 2007 PONTIAC GRAND PRIX GXP. I EXPERIENCED A RIGHT REAR FLAT WHILE DRIVING. I PULLED OVER AND NOTICED THE WHOLE TIRE WAS SERIOUSLY RIPPED. THE OTHER REAR TIRE WAS BALD ON THE INSIDE. WHEN THIS HAPPENED THE VEHICLE ONLY HAD 17000 MILES ON IT. A MONTH LATER MY WIFE'S VEHICLE STARTED HAVING THE SAME PROBLEMS AT 20000 MILES (INSIDE WEAR ON BOTH REAR TIRES. THE DEALERSHIP STATED THAT THESE CARS ARE BAD ABOUT THAT, YOU NEED TO HAVE YOUR TIRES ALIGNED REGULARLY. REPLACED REAR TIRES ON BOTH VEHICLES. *TR

PURCHASED 2007 PONTIAC GRAND PRIX GXP NEW, WITH 98 MILES ON ODOMETER, IN MARCH, 2007. BRIDGESTONE POTENZA TIRES ON ALL FOUR WHEELS AS OEM. TIRES LOSE AIR (CHECKED WITH PROFESSIONAL TIRE GAUGE EVERY WEEK), DOWN TO 24 PSI IN ALL 4 TIRES, AT SAME AMBIENT TEMP, COLD TIRES. WHEN TIRES ARE COLD, THEY RUN AS IF THEY ARE SQUARE. BUMPING ALONG, STEERING WHEEL SHUDDERING SIDE TO SIDE. TAKEN TO DEALER. THEY FORCE-VARIANCE BALANCED ALL WHEELS/TIRES AND ALIGNED VEHICLE, INCLUDING ENGINE CRADLE. CAR STILL HAD SLIGHT STEERING SHUDDER, BECAME WORSE OVER THE NEXT FEW HUNDRED MILES. TAKEN BACK TO DEALER. THEY STATE TIRES "OUT OF ROUND" BUT DID NOT DO ANYTHING TO CORRECT THE SITUATION EXCEPT TO ADD AIR, AND TELL ME THAT ONE TIRE THREW A BALANCING WEIGHT. OVERALL, EVEN WITH PROPER INFLATION, PROPER ALIGNMENT OF ALL COMPONENTS (STEERING AND ENGINE CRADLE), INCLUDING PROPER FORCE-VARIANCE BALANCING, THE TIRES CAUSE THE VEHICLE TO PULL VIOLENTLY LEFT OR RIGHT, DEPENDING ON THE ANGLE OR CROWN OF THE ROAD. ALSO, PULL SO HARD GOING OVER ROAD IMPERFECTIONS, THAT STEERING WHEEL COMES OUT OF MY HANDS. DROVE SEVERAL OTHER IDENTICAL VEHICLES WITH OTHER BRAND (PIRELLI) TIRES, WITH NO PROBLEM. DEFECTIVE TIRES AT ALL FOUR WHEELS. BRIDGESTONE POTENZA'S. HAVE REQUESTED THAT SERVICE MANAGER REPLACE ALL FOUR TIRES WITH PIRELLI'S (THEY ARE THE ONLY OTHER MANUFACTURER WHICH MAKES 18" TIRES COMPATIBLE WITH MY GXP, WHICH USES TWO SEPARATE TIRE SIZES FOR FRONT AND BACK. THE BRIDGESTONE TIRES ARE DANGEROUS AND SHOULD BE RECALLED OR REPLACED. *TR
