Inflation pressures specified on the placard are
always “cold tire inflation pressure”. Cold tire
inflation pressure is defined as the tire pressure
after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after
sitting for a minimum of three hours. The cold tire
inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
Check tire pressures more often if subject to a
wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature change.
Keep this in mind when checking tire pressure
inside a garage, especially in the Winter.
Example: If garage temperature = 68°F (20°C)
and the outside temperature = 32°F (0°C) then
the cold tire inflation pressure should be increased
by 3 psi (21 kPa), which equals 1 psi (7 kPa) for
every 12°F (7°C) for this outside temperature
condition.
Tire pressure may increase from 2 to 6 psi (13 to
40 kPa) during operation. DO NOT reduce this
normal pressure build up or your tire pressure will
be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits. Where
speed limits or conditions are such that the vehicle
can be driven at high speeds, maintaining correct
tire inflation pressure is very important. Increased
tire pressure and reduced vehicle loading may be
required for high-speed vehicle operation. Refer to
an authorized tire dealer or original equipment
vehicle dealer for recommended safe operating
speeds, loading and cold tire inflation pressures.
Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be repaired if
it meets the following criteria:
The tire has not been driven on when flat.
The damage is only on the tread section of your
tire (sidewall damage is not repairable).
The puncture is no greater than a ¼ of an inch
(6 mm).
Consult an authorized tire dealer for tire repairs
and additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical
size and service description (Load Index and
Speed Symbol). Replace the tire pressure sensor
as well as it is not designed to be reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a
rapid loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A Run
Flat mode occurs when the tire inflation pressure is
of/or below 14 psi (96 kPa). Once a Run Flat tire
reaches the Run Flat mode it has limited driving
capabilities and needs to be replaced immediately.
A Run Flat tire is not repairable. When a Run Flat
tire is changed after driving with underinflated tire
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added strain
on your tires could cause them to fail. You could
have a serious collision. Do not drive a vehicle
loaded to the maximum capacity at continuous
speeds above 75 mph (120 km/h).
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision.
Always use radial ply tires in sets of four. Never
combine them with other types of tires.

286SERVICING AND MAINTENANCE
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
that you use tires equivalent to the originals in size,
quality and performance when replacement is
needed
Ú
page 285. 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.
See the Tire Sizing Chart example found in the “Tire
Safety Information” section of this manual for
more information relating to the Load Index and
Speed Symbol of a tire Ú page 275.
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.
21_LD_OM_EN_USC_t.book Page 286

SERVICING AND MAINTENANCE287
Summer tires do not contain the all season
designation or mountain/snowflake symbol on the
tire sidewall. Use Summer tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a
“mountain/snowflake” symbol on the tire sidewall.
If you need snow tires, select tires
equivalent in size and type to the original
equipment tires. Use snow tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
Snow tires generally have lower speed ratings than
what was originally equipped with your vehicle and
should not be operated at sustained speeds over
75 mph (120 km/h). For speeds above 75 mph
(120 km/h) refer to original equipment or an
authorized tire dealer for recommended safe
operating speeds, loading and cold tire inflation
pressures.
While studded tires improve performance on ice,
skid and traction capability on wet or dry surfaces
may be poorer than that of non-studded tires. Some
states prohibit studded tires; therefore, local laws
should be checked before using these tire types.
SPARE TIRES — IF EQUIPPED
NOTE:For vehicles equipped with Tire Service Kit instead
of a spare tire Ú
page 231.
For restrictions when towing with a spare tire
designated for temporary emergency use
Ú
page 119.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare tire and
wheel equivalent in look and function to the original
equipment tire and wheel found on the front or rear
axle of your vehicle. This spare tire may be used in
the tire rotation for your vehicle. If your vehicle has
this option, refer to an authorized tire dealer for the
recommended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency
use only. You can identify if your vehicle is equipped
with a compact spare by looking at the spare tire
description on the Tire and Loading Information
Placard located on the driver’s side door opening
or on the sidewall of the tire. Compact spare tire
descriptions begin with the letter “T” or “S”
preceding the size designation. Example: T145/
80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first
opportunity.
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since
the wheel is designed specifically for the compact
spare tire. Do not install more than one compact spare
tire and wheel on the vehicle at any given time.
WARNING!
Do not use Summer tires in snow/ice conditions.
You could lose vehicle control, resulting in severe
injury or death. Driving too fast for conditions also
creates the possibility of loss of vehicle control.
CAUTION!
Because of the reduced ground clearance, do not
take your vehicle through an automatic car wash
with a compact or limited use temporary spare
installed. Damage to the vehicle may result.

SERVICING AND MAINTENANCE291
TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles
operate at different loads and perform different
steering, driving, 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 all season
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 245.
The reasons for any rapid or unusual wear should
be corrected prior to rotation being performed.
The suggested rotation method is the “rearward
cross” shown in the following diagram. This rotation
pattern does not apply to some directional tires that
must not be reversed. Tire Rotation (Rearward Cross)
DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in
addition to these grades.
CAUTION!
To avoid damage to your vehicle or tires, observe
the following precautions:
Because of restricted traction device clearance
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 instruc
-
tions on the method of installation, operating
speed, and conditions for use. Always use the
suggested operating speed of the device manufac -
turer’s if it is less than 30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
