Maintenance and Specifications Never spin the tires in excess of the 35 mph (55 km/h) point indicated on the speedometer. Highway hazards No matter how carefully you drive there's always the possibility that you may eventually have a flat tire on the highway. Drive slowly to the closest safe area out of traffic. This may further damage the flat tire, but your safety is more important. If you feel a sudden vibration or ride disturbance while driving, or you suspect your tire or vehicle has been damaged, immediately reduce your speed. Drive with caution until you can safely pull off the road. Stop and inspect the tires for damage. If a tire is under-inflated or damaged, deflate it, remove wheel and replace it with your spare tire and wheel. If you cannot detect a cause, have the vehicle towed to the nearest repair facility or tire dealer to have the vehicle inspected. SNOW TIRES AND CHAINS Snow tires must be the same size and grade as the tires you currently have on your vehicle. 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 SAE Class S chains. • 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. 274 2004 F150 (f12) Owners Guide (post-2002-fmt) USA English (fus)
