Pontiac Grand Prix Tires Safety Report | Mar 22, 2007
Reported on Mar 22, 2007
| 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 | |
