1991 Chevrolet Suburban

I HAVE A SET OF HANKOOK OPTIMO 727 TIRES ON MY FAMILY SUBURBAN, AND ONE OF THEM BLEW OUT SUDDENLY, AND UNEXPECTEDLY. THE TIRE THAT BLEW OUT ONLY HAD 14,596 MILES ON IT. THE SIZE IS P235-75-15. ALL FOUR OF THESE TIRES WERE INSTALLED IN FEBRUARY 2016, AND THE VEHICLE WAS ALWAYS KEPT IN MY GARAGE. THE TIRE THAT BLEW OUT SHOWED NO SIGNS OF SUN OZONE DEPLETION, AND AGAIN, IT NEVER SAT OUTSIDE IN THE SUN. ADDITIONALLY, THE TIRE THAT BLEW OUT HAD ALOT OF TREAD DEPTH LEFT. THE VEHICLE WAS NOT OVERLOADED, AS I WAS THE ONLY PERSON IN IT AT THE TIME OF THE BLOWOUT. I WAS SIMPLY DRIVING ABOUT 72 MPH DOWN INTERSTATE 65, JUST SOUTH OF LOUISVILLE, KY, I FELT SOME VIBRATION FOR ABOUT ONE MINUTE, THEN BOOM!, THE TIRE LET GO. I'M DISAPPOINTED IN HANKOOK TIRES, AND WILL NEVER BUY ANOTHER.

FRAME WHERE STEERING BOX IS ATTACHED FAILED. FLEXING FROM NORMAL USE CAUSED THE AREA AROUND THE MOUNTING BOLTS TO CRACK AND WOULD ULTIMATELY SEPARATE THE STEERING BOX FROM THE FRAME IF LEFT UNREPAIRED. REPORTS OF FRAME FAILURES ON 4X4 VERSIONS HAVE BEEN CIRCULATING FOR SOME YEARS DUE TO THE HIGHER STRESS CAUSED BY THE FRONT AXLE AND THE USE OF OVERSIZED TIRES. IN THIS CASE THE SUBURBAN IS A 1/2 TON 2WD UNIT AND HAS ALWAYS RUN ON FACTORY SIZED TIRES. CRACKS WERE FIRST NOTICED JANUARY 2005 WITH 106744 MI DURING A REPAIR JOB FOR A LOOSE FRAME RIVET. CURRENTLY, DECEMBER 2010 AND 206000 MI., CRACKS HAVE FORMED ON ALL MOUNTING LOCATIONS AND REQUIRES A FRAME REPAIR KIT. REPAIR INCLUDES GRINDING AND WELDING OF CRACKS; AND WELDING ADDITIONAL REENFORCING PLATES TO STRENGTHEN THE AREA.

WHILE DRIVING 60-65 MPH AND TOWING A TRAILER, 2 LUG BOLTS SNAPPED OFF THE HUB AND ONE OTHER BOLT WAS LOOSE CAUSING VEHICLE TO JACKKNIFE AND DROVE OFF THE ROAD.

ON THE 18TH OF MAR 2001, AFTER FILLING UP MY GAS TANK, I GOT IN MY VEHICLE ATTEMPTED TO PUT MY SEAT BELT ON AND ENDED UP LYING FLAT ON MY BACK. AS LUCK WOULD HAVE NO KIDS WERE SITTING BEHIND ME. A SINGLE GRADE 8 BOLT BROKE. A FEW YEARS BACK WHEN THIS VEHICLE HAD ABOUT 100K ON IT THE SAME THING HAPPENED. AT THAT TIME THE DEALER (PERFORMANCE CHEVY IN SACRAMENTO CA) TOLD ME THERE WAS A CAMPAIN TO REPLACE THE BOLTS FROM GRADE 5 TO GRADE 8. APPARENTLY THE GRADE 5 LASTED LONGER THAN THE GRADE 8. THE DEALER HERE IN OGDEN SAYS THE VEHICLE IS TO OLD AND THERE IS NO PROVISION FOR MAKING THIS A SAFER SEAT. IF THIS HAD ACCURED WHILE DRIVING THERE ISNO TELLING WHAT MIGHT HAVE HAPPENED. I AM NOT A COMPLAINER BUT THIS WHOLE THING SEEMS WRONG. AND WHEN I GO TO SELL THIS VEHICLE HOW CAN I SAY IT IS A SAFE CAR. HOPE YOU CAN HELP,AND I APPRECIATE YOU LOOKING INTO THIS, I CANT BELIEVE I AM THE ONLY ONE WITH THIS PROBLEM.. PHILLIP WILLIAMS. *AK

DEAR NHTSA, I HAD MANY TIRE FAILURES WITH MY FIRESTONE ATX II TIRES. I PURCHASED THEM WHEN MY CAR HAD 57,358 MILES ON 03/19/94. I DROVE APPROXIMATELY 20,000 MILES PER YEAR. ALL THE PREVIOUS TIRE FAILURES WERE BLOWOUTS I HAD WHILE DRIVING WITH MY FAMILY ON THE HIGHWAY. EACH TIME I WENT TO THE FIRESTONE SERVICE CENTER FOR PRORATED TIRE REPAIRS. THEY KEPT TRYING TO BLAME MY BLOWOUTS ON MY ALUMINUM WHEEL RIMS ALTHOUGH I NEVER HAD ANY PROBLEMS WITH MY PREVIOUS UNIROYAL TIRES. IN 1998 AFTER YET ANOTHER TIRE PROBLEM I SWITCHED TO MICHELINS, AND I HAVE SINCE SOLD THE VEHICLE IN 8/99. AT THE TIME OF THESE PROBLEMS, I WAS CONCERNED AS TO THE AMOUNT OF BLOWOUTS I HAD, AND UNTIL THE RECALL CAME OUT I THOUGHT IT MIGHT BE OF SOME RELEVANCE TO YOU. I HAVE ALL MY ORIGINAL PAPERWORK FROM FIRESTONE. MANY OF THE REPLACEMENT TIRES I HAD CARRIED IN TO THE STORE SO I DON'T HAVE EXACT MILAGE OF THE TIRES. I DO POSSIBLY HAVE AT LEAST ONE OF THESE TIRES ON MY PROPERTY BUT IT WOULD REQUIRE SOME EFF
