Wheels and Tires USING SNOW CHAINS WARNING Snow tires must be the same size, load index, speed rating as those originally provided by Ford. Use of any tire or wheel not recommended by Ford can affect the safety and performance of your vehicle, which could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. Additionally, the use of non-recommended tires and wheels could cause steering, suspension, axle, transfer case or power transfer unit failure. Note: Do not use snow chains on vehicles with 20 inch wheels and tires. The tires on your vehicle have all-weather treads to provide traction in rain and snow. However, in some climates, you may need to use snow tires and cables. If you need to use cables, it is recommended that steel wheels (of the same size and specifications) be used, as cables may chip aluminum wheels. Note: The suspension insulation and bumpers will help prevent vehicle damage. Do not remove these components from your vehicle when using snow tires and chains. Follow these guidelines when using snow tires and chains If possible, avoid fully loading your vehicle Use only SAE Class S chains. Install chains securely, verifying that the chains do not touch any wiring, brake lines or fuel lines. E166988 If your vehicle is equipped with dual rear wheels it is recommended that the front and rear tires (in pairs) be rotated only side to side. We do not recommend splitting up the dual rear wheels. Rotate them side to side as a set. After tire rotation, inflation pressures must be adjusted for the tires new positions in accordance with vehicle requirements. Sometimes irregular tire wear can be corrected by rotating the tires. 281 Super Duty (), enUSA
