Tires, Wheels and Loading Rotation, pressure adjustment and successful completion of the TPMS reset procedure Sensor 1: 80 psi Sensor 2: 80 psi Sensor 3: 50 psi Sensor 4: 50 psi Tire rotation and air pressure adjustment followed by sensor resetting will ensure the system is properly programmed for vehicles with different front and rear tire pressures and reduce the risk of a false low tire warning. In this situation, the TPMS warning light will be off. SNOW TIRES AND CHAINS Snow tires must be the same size and grade as the tires you currently have on your vehicle. Note: Do not use snow chains on front tires of vehicles with 20" 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 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. 235 2008 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
