FORD 2002 Explorer Sport Trac v.2 - Manual (Page 180)

Do not replace your tires with “high performance” tires or larger
size tires.
Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier to lose control and roll
over.
Tires that are larger or smaller than your vehicle’s original tires may
affect the accuracy of your speedometer.
SNOW TIRES AND TRACTION DEVICES
Snow tires must be the same size and grade as the original tires.
Your tires have all-weather treads to provide traction in the rain and
snow. In some climate, using snow tires or traction devices may be
necessary. For Motor Company offers tire cables as a Ford approved
accessory and recommends use of these or SAE class “S” cables. See
your dealer for more information.
Follow these guidelines:
• Do not use tire cables or chains with P255/70R16 size tires.
• Cables or chains should only be used on the rear wheels.
• Install cables or chains securely, verifying that they do not touch any
wiring, brake lines or fuel lines.
• Avoid overloading your vehicle.
• Do not use cables or chains on dry roads.
• Do not exceed 48 km/h (30 mph).
• Drive cautiously.
Remove the cables or chains when they are no longer needed.
