Tires, Wheels and Loading When mounting replacement tires and wheels, you should not exceed the maximum pressure indicated on the sidewall of the tire to set the beads without additional precautions listed below. If the beads do not seat at the maximum pressure indicated, re-lubricate and try again. When inflating the tire for mounting pressures up to 20 psi (138 kPa) greater than the maximum pressure on the tire sidewall, the following precautions must be taken to protect the person mounting the tire: 1. Make sure you have the correct tire and wheel size 2. Lubricate the tire bead and wheel bead area again 3. Stand at a minimum of 12 ft. (3.7 m) away from the tire wheel assembly 4. Use both eye and ear protection For a mounting pressure more than 20 psi (138 kPa) greater than the maximum pressure, a Ford Dealer or other tire service professional should do the mounting. Always inflate steel carcass tires with a remote air fill with the person inflating standing at a minimum of 12 ft. (3.7 m) away from the tire wheel assembly. Important: Remember to replace the wheel valve stems when the road tires are replaced on your vehicle. It is recommended that the two front tires or two rear tires generally be replaced as a pair. The tire pressure sensors mounted in the wheels (if equipped) are not designed to be used in aftermarket wheels. The use of wheels or tires not recommended by Ford Motor Company may affect the operation of your Tire Pressure Monitoring System (if equipped). If the TPMS indicator is flashing, your TPMS is malfunctioning. Your replacement tire might be incompatible with your TPMS, or some component of the TPMS may be damaged (if equipped). Safety practices Driving habits have a great deal to do with your tire mileage and safety. • Observe posted speed limits • Avoid fast starts, stops and turns • Avoid potholes and objects on the road 215 2008 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
