NHTSA Complaint #10064237 — 1997 NISSAN QUEST

HAVE A SET OF REGATTA II, 215SR75. @25,000 - 30,000 MILES ON TIRES. EXPERIENCED SHIMMYING AT LOW SPEEDS AND VIBRATION AT HIGH SPEEDS. CHECK INFLATION FREQUENTLY AND PUT AIR IN WHEN NECESSARY. HAD A PASSENGER SIDE REAR TIRE BLOW OUT RECENTLY. APPEARED AS IF SIDE WALLS HAD BURST. NEVER SEEN ANYTHING LIKE IT IN ALL MY LIFE. (SIDE NOTE: HAD RECENTLY HAD BRAKE PADS REPLACED, THE TIRE IN QUESTION WAS ON THE FRONT, MECHANIC DISCOVERED TIRE TO BE SERIOUSLY OUT OF BALANCE AND HAD DIFFICULT TIME TRYING TO BALANCE IT, WHICH IS WHY HE PUT IT ON THE REAR) AFTER TIRE BLEW OUT THE TIRE DEALER SAID SIDE WALLS WERE PROBABLY WEAKENED BY UNDERINFLATION MOST LIKELY CAUSED BY A SLOW LEAK. THIS EXPLANATION IS INADEQUATE. HE REPLACED THE TIRE AT FULL PRICE MINUS $11.00 AND SAID IT WAS NOT A WARRANTY ISSUE AS THE WARRANTY ONLY COVERED TREAD WEAR. AFTER REPLACING THE TIRE THE VEHICLE (NISSAN QUEST MINIVAN) STILL SHIMMIES AT LOW SPEED AND VIBRATES AT HIGH SPEED. MY CONCERNS ARE: 1. ARE THE THREE REMAINING ORIGINAL REGATTA II TIRES IN IMMENENT DANGER OF EXPLODING LIKE THE OTHER ONE? 2.CONSIDERING THE DIFFICULTY BALANCING THE ONE TIRE THAT BLEW, WAS THAT TIRE DEFECTIVE? 3. COULD THE SAME PROBLEM BE OCCURING IN MY OTHER 3 TIRES CREATING A SERIOUS, DANGEROUS SITATION? *AK
