Maintenance and Specifications When the tread is worn down to 1/16th of an inch (2 mm), tires must be replaced to prevent your vehicle from skidding and hydroplaning. Built-in treadwear indicators, or "wear bars", which look like narrow strips of smooth rubber across the tread will appear on the tire when the tread is worn down to 1/16th of an inch (2 mm). When you see these "wear bars", the tire is worn out and should be replaced. Inspect your tires frequently for any of the following conditions and replace them if one or more of the following conditions exist: • Fabric showing through the tire rubber • Bulges in the tread or sidewalls • Cracks or cuts on the sidewalls • Cracks in the tread groove • Impact damage resulting from use • Separation in the tread • Separation in the sidewall • Severe abrasion on the sidewall If your vehicle has a leak in the exhaust system, a road tire or the spare tire may be exposed to hot exhaust temperatures requiring the tire to be replaced. Tire Replacement Requirements Your vehicle is equipped with tires designed to provide safe ride and handling capability. Only use replacement tires and wheels that are the same size and type (such as P-metric versus LT-metric or all-season versus all-terrain) 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. If you have questions regarding tire replacement, see an authorized Ford or Lincoln/Mercury dealer. 274 2004 Freestar (win) Owners Guide (post-2002-fmt) USA English (fus)
