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.

TL*THE CONTACT OWNS A 1991 CHEVROLET SUBURBAN. WHILE DRIVING 60 MPH, THE CONTACT EXPERIENCED VALVE STEM FAILURE, WHICH CAUSED IT TO CRACK. THE TIRE FLATTENED AND WAS RUINED AS A RESULT. THE DEALER STATED THAT THEY NEVER HEARD OF THE VALVE STEM FAILURE. THROUGH ONLINE RESEARCH, THE CONTACT EXPERIENCED VARIOUS RECALLS PERTAINING TO VALVE STEM FAILURES AND CRACKS. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 51,000. THE TIRE FAILURE MILEAGE WAS APPROXIMATELY 12,000.

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 EFFORT TO RETRIEVE AND FIND IT. I BELIEVE THAT THE PROBLEM WITH THESE TIRES HAS BEEN GOING ON FOR A LOT LONGER THAN FIRESTONE HAS LED ME TO BELIEVE AND I WOULD BE WILLING TO HELP YOU IN ANY WAY I CAN. I AM ALSO GOING TO CONTACT FIRESTONE' S WEBSITE AND GIVE THEM THIS INFORMATION AS WELL. SINCERELY LISA R. KING( DOT NUMBER: ? TIRE SIZE: P235-75-15 )
