Open the full vehicle complaint log (all categories)HANKOOK OPTIMO TIRES CHUNKING AT 24100 MILES SEVERE ENOUGH TO BE UNSAFE TO DRIVE.. NOTICED AT AROUND 12000. NORMAL STREET AND HIGHWAY DRIVING.
MY FORD FLEX IS EQUIPPED WITH HANKOOK OPTIMO H426 TIRES. AT APPROXIMATELY 9,500 MILES THE VEHICLE BEGAN TO VIBRATE. I'VE TAKEN IT TO THE SHOP 5 TIMES AND EVERYTHING EXCEPT THE TIRES HAS BEEN RULED OUT. AFTER VISITING A WEB SITE I FOUND LITERALLY HUNDREDS OF COMPLAINTS ABOUT THESE TIRES CAUSING EVERYTHING FROM VIBRATION TO BLOWOUTS. I AM CURRENTLY DRIVING A RENTAL WHILE MY CAR IS IN THE SHOP THAT HAS THE SAME TIRES. IT HAS THE SAME VIBRATION. THE EVENT GENERALLY BEGINS AT ABOUT 60 TO 65 MPH HOWEVER THE VIBRATION HAS BEEN NOTICED AS LOW AS 40 MPH. WHEN IT STARTS AT A LOW SPEED IT TURNS INTO A VIOLENT SHAKING THAT SCARES THE HECK OUT OF ME ENOUGH THAT I PULL OFF THE ROAD AND WAIT UNTILL MY NERVES SETTLE TO CONTINUE DRIVING. TODAY IS FEBRUARY 14 2020. THE VIBRATION HAS BEEN OCCURING SINCE ABOUT OCTOBER 25 2019.
