292SERVICING AND MAINTENANCE
NOTE:Wheel valve stem must be replaced as well when
installing new tires due to wear and tear in existing
tires.
Keep dismounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends using tires equivalent to the originals
in size, quality and performance when
replacement is needed Úpage 291. Refer to the
Tire And Loading Information Placard or the
Vehicle Certification Label for the size designation
of your tire. The Load Index and Speed Symbol for
your tire will be found on the original equipment
tire sidewall.
For more information relating to the Load Index
and Speed Symbol of a tire Ú page 282.
It is recommended to replace the two front tires or
two rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels. It is recommended you contact an authorized tire
dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling, and
ride of your vehicle.
TIRE TYPES
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Traction
levels may vary between different all season tires.
All season tires can be identified by the M+S, M&S,
M/S or MS designation on the tire sidewall. Use all
season tires only in sets of four; failure to do so
may adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in
snow or on ice. If your vehicle is equipped with
Summer tires, be aware these tires are not
designed for Winter or cold driving conditions.
Install Winter tires on your vehicle when ambient
temperatures are less than 40°F (5°C) or if roads
are covered with ice or snow. For more
information, contact an authorized dealer.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for your
vehicle. Some combinations of unapproved
tires and wheels may change suspension
dimensions and performance characteristics,
resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpre
-
dictable handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
Never use a tire with a smaller load index or
capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire over -
loading and failure. You could lose control and
have a collision.
Failure to equip your vehicle with tires having
adequate speed capability can result in
sudden tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different
size may result in false speedometer and
odometer readings.

TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle
operate at different loads and perform different
steering, handling, and braking functions. For
these reasons, they wear at unequal rates.
These effects can be reduced by timely rotation of
tires. The benefits of rotation are especially
worthwhile with aggressive tread designs such as
those on On/Off-Road type tires. Rotation will
increase tread life, help to maintain mud, snow,
and wet traction levels, and contribute to a
smooth, quiet ride. For the proper maintenance intervals
Úpage 250.
The reasons for any rapid or unusual wear should
be corrected prior to rotation being performed.
NOTE:The Tire Pressure Monitor System will automati -
cally locate the pressure values displayed in the
correct vehicle position following a tire rotation.
The suggested rotation method is the “rearward
cross” shown in the following diagram.
Tire Rotation (Rearward Cross)
WARNING!
Using tires of different size and type (M+S,
Snow) between front and rear axles can cause
unpredictable handling. You could lose control
and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe
the following precautions:
Because of restricted traction device clear -
ance between tires and other suspension
components, it is important that only traction
devices in good condition are used. Broken
devices can cause serious damage. Stop the
vehicle immediately if noise occurs that could
indicate device breakage. Remove the
damaged parts of the device before further
use.
Install device as tightly as possible and then
retighten after driving about ½ mile (0.8 km).
Autosock traction devices do not require
retightening.
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns and
large bumps, especially with a loaded vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed of
the device manufacturer’s if it is less than
30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION!
