Tires, Wheels and Loading SNOW TIRES AND CHAINS 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 or transfer case/power transfer unit failure. 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 chains. If you need to use chains, it is recommended that steel wheels (of the same size and specifications) be used, as chains may chip aluminum wheels. Follow these guidelines when using snow tires and chains: • Use only cable type chains or chains offered by Ford as an accessory or equivalent. Other conventional link type chains may contact and cause damage to the vehicle's wheel house and/or body. • Do not install chains on the front wheels. Chains on the front wheels may interfere with suspension components. • Chains are not recommended for use on the P275/55R20 tire. • Install chains securely, verifying that the chains do not touch any wiring, brake lines or fuel lines. • Drive cautiously. If you hear the chains rub or bang against your vehicle, stop and re-tighten the chains. If this does not work, remove the chains to prevent damage to your vehicle. • If possible, avoid fully loading your vehicle. • Remove the tire chains when they are no longer needed. Do not use tire chains on dry roads. • The suspension insulation and bumpers will help prevent vehicle damage. Do not remove these components from your vehicle when using snow tires and chains. • Do not exceed 30 mph (48 km/h) with tire chains on your vehicle. 253 2008 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus)
