WE WERE DRIVING APPROX. 70MPH ON INTERSTATE 20 IN GEORGIA NEAR GREENSBORO EXIT. THE TREAD SEPARATED FROM OUR LEFT REAR TIRE AND SENT US OUT OF CONTROL ON THE INTERSTATE HIGHWAY. THIS WAS AT 5:30 P.M. ON FRIDAY AUGUST 19, 2005 IN BUSY TRAFFIC.WE WERE HEADED ACROSS THE MEDIAN WHEN MY HUSBAND JERKED THE WHEEL TO THE RIGHT AND WE HIT THE GUARD RAIL ON THE RIGHT SIDE OF THE HIGHWAY. WE BOUNCED BACK INTO TRAFFIC AND HE SWERVED AGAIN TO THE RIGHT AND WE HIT THE GUARD RAIL AGAIN AND CAME TO A STOP. THIS IS THE MOST HORRIFIC EXPERIENCE OF OUR LIVES. MY 11 YEAR OLD HAS WHIPLASH AND BAD HEADACHES. I HAVE KNEE PROBLEMS AND ALL OF US HAVE EMOTIONAL TRAUMA ISSUES. PLEASE LOOK INTO THIS VERY CLOSELY. I NOTICED OTHER COMPLAINTS HERE IN THIS WEBSITE. THEY ARE P245/75R16 LONG TRAIL TA.
