Inspection and Rotation
Front and rear tires perform different jobs and can wear differently
depending on the types
of
roads driven, your driving habits, etc. To obtain
maximum tire life, you should inspect and rotate your tires regularly.
(
See Section A
of
tbe Maintenance Schedule folder for recommended
rotation intervals. )
Many
car
and
tire dealers will perform a free tire
inspection to look for uneven or abnormal
tire
wear (usually the result
of
wrong inflation pressures, lack
of
regular rotation, improper wheel
alignment, tires out
of
balance, or poor driving habits).
After rotation, adjust the front and rear tire pressures (see Tire
Placard)
and
be
sure to check wheel nut tightness. (Wheel nuts should also be
tightened at certain intervals; see the
"In
Case
of
Emergency" section,
"J
acking Instructions," for further information.
Alignment and Balance
Proper wheel alignment improves tire tread mileage. Your car's
suspension parts should be inspected often and aligned when needed.
(See
the Maintenance Schedule folder for more information.) Ball joints have
built-in wear indicators, and some movement
in
the joints
is
normal.
Improper alignment will not cause the
car
to vibrate. However, improper
toe alignment will cause the tires to roll
at
an angle which will result
in
faster tire wear. Incorrect caster or camber alignment will cause your
tires
towear
unevenly, and can cause the
car
to
"pull"
to the left or right.
Proper tire balancing provides the best riding comfort
an<~
helps to reduce
tire tread wear. Out-of-balance tires can cause annoying vehicle vibration
and uneven tire wear such as cupping and flat spots.
