2004 Chevrolet Express 1500

WE PURCHASED A COMPLETE SET OF GENERAL GRABBER HTS 235/75R16 FOR OUR CHEVY EXPRESS VAN AT DUNN TIRE ON 11/15/08. THEY WERE SUPPOSED TO HAVE A 60K WARRANTY. WE WENT IN FOR THE REQUIRED ROTATIONS AND NOTED THAT THE TREAD DIDN'T SEEM TO BE WEARING WELL. AT THE 20K MILE ROTATION IN JANUARY OF 2011, DUNN TIRE ACKNOWLEDGED THAT THE TIRES WERE NOT PERFORMING AS ADVERTISED AND TOLD US THAT THEY WOULD LIKELY NEED TO ADJUST THE TIRES ON A PRO-RATA BASIS AT THE NEXT ROTATION AT 25K MILES. IT IS OUR BELIEF THAT THE TIRES ARE DEFECTIVE IN SOME WAY. THE ORIGINAL TIRES ON OUR VAN LIVED UP TO THEIR 40K WARRANTY AND WE REPLACED WITH THESE GRABBER HTS TIRES AT 39747 MILES. OUR DRIVING HABITS ARE CONSERVATIVE AND WE HAVE NEVER HAD TO REPLACE TIRES AHEAD OF THE WARRANTY PERIOD. THE TREAD WAS SO BAD ON THESE GRABBER HTS TIRES THAT WE WERE UNABLE TO DRIVE OUR VAN ON SNOWY ROADS DURING THIS PAST WINTER. WE ALSO WERE CONCERNED ABOUT HYDROPLANING ON THE EXPRESSWAY WHEN WE DROVE THE VAN THROUGH HEAVY RAINS THIS PAST WEEKEND WHEN WE DROPPED OFF OUR DAUGHTER AT COLLEGE. WE BELIEVE THESE TIRES ARE HAZARDOUS AND THAT AN INVESTIGATION SHOULD BE INITIATED. IT'S INCONCEIVABLE THAT WE WOULD ONLY GET 25K MILES OUT OF A 60K TIRES. WE FEEL CHEATED AND REALLY DO NOT WANT ANOTHER SET OF GENERAL TIRES ON A PRO-RATA BASIS. *TR
