DRIVING AT 55 MPH ON HWY 528 ABOUT 20 MILES EAST OF ORLANDO, THE TRUCK BEGAN TO SHAKE AND THEN WE SUFFERED A CATASTROPHIC TREAD SEPARATION OF OUR REAR DRIVER'S SIDE TIRE. WE WERE TRAILERING A CAMPER AT THE TIME. BY THE TIME I WAS ABLE TO BRING THE TRUCK TO A STOP ON THE SHOULDER OF THE HIGHWAY WE HAD SUSTAINED CLOSE TO $3000 WORTH OF DAMAGE TO THE REAR DRIVER'S SIDE FENDER AND WHEEL WELL. THIS WAS THE 2ND KUMHO LT 245/75 R16 OF THE SET THAT HAD A SEPARATION. THE FIRST ONE WE WERE ABLE TO SLOW DONE IN TIME TO PREVENT ANY DAMAGE TO THE VEHICLE. THE TIRES ONLY HAD 18000 MILES ON THEM AND INFLATION PRESSURES HAD BEEN CHECKED WITHIN 24 HOURS OF THE INCIDENT EACH TIME. AFTER CALLING KUMHO SEVERAL TIMES AFTER THE 1ST INCIDENT, THEY GAVE A 67 DOLLAR CREDIT ON THE TIRE. THE SECOND TIME THEY HAVE NOT RETURNED MY MULTIPLE PHONE CALLS. I HAVE NOW REPLACED AND KEPT THE REMAINING TIRES OF THE SET. I KEPT THEM HOPING THAT NHTSA WOULD TAKE THEM FOR TESTING. I FILED A COMPLAINT BY PHONE WITH NHTSA ON 11/3015 AND MEKO TOLD ME I WOULD BE RECEIVING FORMS IN THE MAIL TO COMPLETE THE COMPLAINT. IT HAS NOW BEEN OVER 2 MONTHS, AND I HAVE NOT RECEIVED ANYTHING FROM YOU! MY COMPLAINT # WAS 10807471. THESE ARE DANGEROUS FAULTY TIRES AND NEED TO BE RECALLED. SOMEONE NEEDS TO HOLD KUMHO RESPONSIBLE FRO THESE TIRES BEFORE MORE LIVES ARE LOST SECONDARY TO CATASTROPHIC SEPARATIONS.

I HAVE MICHELIN TIRES ON ALL FOUR OF MY VEHICLES AND HAVE NEVER HAD ONE CRACK EVEN ON 6 YEAR OLD TIRES. I CALLED MICHELIN, BUT THEY SAY THAT IS NORMAL WEATHERING. NOW THEY ARE CRACKING TO THE POINT THAT THE TREAD COULD EASILY SEPARATE. MY TIRE DEALER IS GOING TO REPLACE THEM, BUT MICHELIN WILL NOT REIMBURSE THEM AS MICHELIN DENIES THERE IS A PROBLEM. I SEE FROM ONLINE BLOGS THAT SIDEWALL CRACKS IN THIS TIRE ARE APPEARING ALL OVER THE COUNTRY AND MICHELIN IS STONEWALLING IT. THIS IS A LIFE THREATENING SITUATION WHICH SHOULD BE INVESTIGATED. *TR *JS
