Hankook dynapro as p235-70-r17s tire with approximately 60% wear (according to Ford dealership where vehicle was purchased and tires replaced). During normal driving noticed abnormal bumping that appeared to be associated with tire or front end. Took vehicle to shop to check balance and wheel alignment. Tech found the above described tire had separated and the steel belting was protruding through the tread and top of sidewall. Tire was about to fail. Driver contacted hankook and forwarded a photograph of the tire to the representative. Hankook agreed to a 40% refund of the amount that Ford paid (not what I paid) for the tire if I would return the tire or a piece from it containing the dot number. Ford took the tire for return to hankook. Three weeks have passed and I have not heard back from Ford or hankook.
Hankook dynapro atm 285/55/r20 tires developing severe sidewall crack. Purchased 4 about a year ago. Had to replace 2 this spring and now have to replace 2 more again which means I will have spent an additional $800 for adjustments. Tires are religiously checked and are rotated every 10,000 miles.
