The National Highway Traffic Safety Administration (NHTSA) has upgraded its probe of other Firestone tires to a full-scale defect investigation. The latest warning, which is not a
recall at this time, includes Wilderness AT 16-inch tires installed on 1996-98 Ford F-150
pickups, and 15-inch ATX tires used on 1991 Chevrolet Blazers and 1991-94 Nissan pickups.
