Maintenance and care When replacing full size tires, never mix radial, bias-belted, or bias-type tires. Use only the tire sizes that are listed on the tire pressure decal. Make sure that all tires are the same size, speed rating, and load-carrying capacity. Use only the tire combinations recommended on the decal. If you do not follow these precautions, your vehicle may not drive properly and safely. Make sure that all replacement tires are of the same size, type, load-carrying capacity and tread design (e.g., "All Terrain", etc.), as originally offered by Ford. Do not replace your tires with "high performance" tires or larger size tires. Failure to follow these precautions may adversely affect the handling of the vehicle and make it easier to lose control and roll over. Your vehicle requires the use of the following tire types: • A/S BSW P255/70R 16 • A/T OWL P255/70R 16 • A/T OWL P265/70R 17 186
