Ford 2005 P207 Explorer Sport Trac Owner's Manual page 435

Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by a qualified technician
at a Ford or Lincoln/Mercury dealer. Front wheel drive (FWD) vehicles
and those with an independent rear suspension (if equipped) may
require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire rotation
Rotating your tires at the recommended interval (as indicated in the
scheduled maintenance information that comes with your vehicle) will
help your tires wear more evenly, providing better tire performance and
longer tire life. Unless otherwise specified, rotate the tires approximately
every 5,000 miles (8,000 km).
