Maintenance and Specifications Never mix radial bias-belted tires, or bias-type tires. Use only the tire sizes that are listed on the Certification Label. Make sure that all tires are the same size, speed rating, and load carrying capacity. Use only the tire combinations recommended on the label. If you do not follow these precautions, your vehicle handling may be effected which can lead to loss of vehicle control, vehicle rollover and/or personal injury. Make sure that all replacement tires are of the same size, type, load-carrying capacity and tread design as originally offered by Ford. Do not replace your tires with "high performance" tires or larger size tires. Failure to follow these precautions, your vehicle handling may be adversely effected which can lead to loss of vehicle control, vehicle rollover and/or personal injury. Tires that are larger or smaller than your vehicle's original tires may affect the accuracy of your speedometer. Tire pressure monitoring system (TPMS) (if equipped) The tire pressure monitoring system provides the driver with a warning message indicating when tire pressure is severely low or high. This system is a supplement to normal tire maintenance including regular manual inspections. The device will inform the operator of severe low or high inflation pressures, but may not illuminate for less severe discrepancies in inflation pressure. The system uses radio-frequency pressure sensors to monitor the tire pressure on all tires including the spare. The sensors transmit the tire pressure readings to the receiver module located in the vehicle. The receiver module then transmits the status to the message center. For more tire warning information, refer to the Message Center in the Driver controls chapter. 257 2003 Explorer (exp) Owners Guide (post-2002-fmt) USA English (fus)
