TIRE BLOWOUT BRAND: HANKOOK MODEL: DYNAPRO AS MADE: KOREA DOT: T79C PJNH 4008 I HAVE HAD MULTIPLE PROBLEMS WITH THESE TIRES, WHILE DRIVING HOME MY FRONT TIRE BLEW OUT ON MY 2009 FORD F150 TRUCK CAUSING ME TO HIT THE SIDE MEDIAN WHICH THEN CAUSED MY TRAILER TIRE TO BLOW OUT AND BENT MY TRAILER TIRES RIM AS WELL. WHEN THIS INCIDENT OCCURRED MY TRUCK ONLY HAD A LITTLE OVER 3000 MILES ON IT. I TOOK IT TO MY FORD DEALER AND THEY ARGUED THAT SOME ONE CUT IT. WHEN I TOOK IT TO ANOTHER TIRE SHOP BEFORE THEY EVEN LOOKED AT IT THEY SAID THAT THE RIM ON THE TIRE HAD CAUSED THE CUT. AND IT INDEED WAS FORDS FAULT. I REPLACED THE TIRE AND BOUGHT A NEW ONE FROM DISCOUNT TIRE. SAME BRAND SAME MODEL SO IT WOULD MATCH. TODAY ON JAN 14 2010 I TOOK MY TRUCK IN FOR AN OIL CHANGE AND TIRE ROTATION, WHEN THEY ROTATED MY TIRES THE NEW TIRE I BOUGHT HAD A MASSIVE BALL ON THE INSIDE OF IT. THE NEW TIRE ONLY HAD 3000 MILES OF WEAR. THESE TIRES ARE THE STOCK TIRES THAT FORD HAS BEEN USING ON THEIR F-150 SERIES SINCE 2007 AND PROBABLY LONGER. I HAD A SET OF THESE TIRES ON MY 2007 F-150 AND AT 9000 MILES THEY STARTED FORMING BALLS ON THE TIRES, AND THE FRONT TIRES BEGAN TO CUP OUTWARD. BOTH TRUCKS I HAVE PURCHASED FROM SPIKES FORD IN MISSION TEXAS. WHEN I PURCHASED MY VEHICLES THEY CAME WITH TIRE ROAD HAZARD WARRANTY WHEN I TOOK IT TO FORD THEY TOLD ME IT WAS MY PROBLEM AND WOULD NOT COVER ANYTHING. IN MY OPINION THESE PROBLEMS ON TWO SEPARATE VEHICLES TWO YEAR
