Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 391
andWheel Replacement on page 396for
more information.
Make sure the spare tire is stored securely.
Push, pull, and then try to rotate or turn the tire.
If it moves, use the wheel wrench to tighten
the cable. SeeChanging a Flat Tire on page 400.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehicle.
The rst rotation is the most important, see
Scheduled Maintenance on page 442.When rotating your tires, always use one of the
correct rotation patterns shown here.
If your vehicle has a compact spare tire or a spare
tire that does not match your vehicle’s road tires
and wheels, in size and type, do not include
the spare in the tire rotation.
After the tires have been rotated, adjust the front
and rear in ation pressures as shown on the
Tire and Loading Information label. For the
location of the Tire and Loading Information label
seeLoading Your Vehicle on page 293. Make
certain that all wheel nuts are properly tightened,
see “Wheel Nut Torque” underCapacities and
Speci cations on page 437for the proper wheel
nut torque speci cation.

{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 400.
Any time you rotate the vehicle’s tires the Tire
Pressure Monitor System (TPMS) will need to be
reset. The TPMS identi cation codes will need
to be matched to the tire and wheel position.
See “TPMS Sensor Identi cation Codes” under
Tire Pressure Monitor System on page 385.
When It Is Time for New Tires
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
Some commercial truck
tires may not have
treadwear indicators.
You need a new tire if any of the following
statements are true:
You can see the indicators at three or more
places around the tire.
You can see cord or fabric showing through
the tire’s rubber.
The tread or sidewall is cracked, cut or
snagged deep enough to show cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
