WHILE DRIVING THROUGH AN OPEN FIELD THAT HAD JUST RECENTLY BE HARVESTED FOR SOY BEANS. I WAS MAKING A LEFT TURN WHEN THE RIGHT FRONT TIRE SUDDENLY WENT FLAT. THIS CAUSED THE RIGHT FRONT RIM TO PLUNGE INTO THE GROUND. THIS RESULTED IN THE TRUCK ROLLING OVER. (TIRESIZE: P265/75R16)( DOT NUMBER: TIRE SIZE: P265/75R16 )
