Tires, replacement requirements TIRES, REPLACEMENT REQUIREMENTS Your 4WD or AWD vehicle is equipped with tires designed to provide for safe ride and handling capability. Do not use a size and type of tire and wheel other than that originally provided by Ford because it can affect the safety and performance of your vehicle, which could lead to loss of vehicle control or rollover and serious injury. Make sure all tires and wheels on the vehicle are of the same size, type, tread design, brand and load-carrying capacity. If you have questions regarding tire replacement, see an authorized Ford or Lincoln/Mercury dealer. If you nevertheless decide to equip your 4WD or AWD for off-road use with tires larger than what Ford recommends, you should not use these tires for highway driving. If you use any tire/wheel combination not recommended by Ford, it may adversely affect vehicle handling and could cause steering, suspension, axle or transfer case failure. Do not use"aftermarket lift kits" or other suspension modifications, whether or not they are used with larger tires and wheels. These "aftermarket lift kits" could adversely affect the vehicle's handling characteristics, which could lead to loss of vehicle 15
