Section 04-04: Wheels and Tires | 1996 F-150, F-250, F-350, F-Super Duty Chassis Cab, F-Super Duty Motorhome Chassis and Bronco Workshop Manual |
The original equipment tires have built-in tread wear indicators to show when tires need replacement. These indicators will appear as 12.7mm (1/2-inch) wide bands when the tire tread depth becomes 1.58mm (1/16-inch). When the indicators appear in two or more adjacent grooves, at three locations around the tire, or when cord or fabric is exposed, tire replacement due to tread wear is required.
