Tire And Loading Information Placard

Tire And Loading Information Placard
This placard tells you important information about
the:

1. Number of people that can be carried in the
vehicle.

2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, and spare tires.
Loading
The vehicle maximum load on the tire must not
exceed the load carrying capacity of the tire on your
vehicle. You will not exceed the tire's load carrying
capacity if you adhere to the loading conditions,
tire size, and cold tire inflation pressures specified
on the Tire And Loading Information Placard
Úpage 195.
NOTE:Under a maximum loaded vehicle condition, gross
axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded.
For further information on GAWRs, vehicle loading,
and trailer towing, see Ú page 195.

404SERVICING AND MAINTENANCE
Tread Wear Indicators
Tread wear indicators are in the original equipment
tires to help you in determining when your tires
should be replaced.

Tire Tread
These indicators are molded into the bottom of the
tread grooves. They will appear as bands when the
tread depth becomes a 1/16 of an inch (1.6 mm).
When the tread is worn to the tread wear
indicators, the tire should be replaced.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
Driving style
Tire pressure — Improper cold tire inflation pres
-
sures can cause uneven wear patterns to
develop across the tire tread. These abnormal
wear patterns will reduce tread life, resulting in
the need for earlier tire replacement
Distance driven
Performance tires, tires with a speed rating of V
or higher, and Summer tires typically have a
reduced tread life. Rotation of these tires per
the vehicle scheduled maintenance is highly
recommended
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 Ú page 404. 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 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 397.
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.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.
1 — Tread Wear Indicators
WARNING!
Tires and the spare tire should be replaced after
six years, regardless of the remaining tread.
Failure to follow this warning can result in
sudden tire failure. You could lose control and
have a collision resulting in serious injury or
death.

23_JT_OM_EN_USC_t.book Page 404

406SERVICING AND MAINTENANCE
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 that
are 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, please refer to “Tire Service Kit” in
“In Case Of Emergency” for further information.
For restrictions when towing with a spare tire
designated for temporary emergency use
Ú page 202.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle is 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.
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.
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.

23_JT_OM_EN_USC_t.book Page 406

SERVICING AND MAINTENANCE407
Full Size Spare — If Equipped
The full size spare is for temporary emergency use
only. This tire may look like the originally equipped
tire on the front or rear axle of your vehicle, but it is
not. This spare tire may have limited tread life.
When the tread is worn to the tread wear
indicators, the temporary use full size spare tire
needs to be replaced. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle
at the first opportunity.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary
emergency use only. This tire is identified by a label
located on the limited use spare wheel. This label
contains the driving limitations for this spare. This
tire may look like the original equipped tire on the
front or rear axle of your vehicle, but it is not.
Installation of this limited use spare tire affects
vehicle handling. Since it is not the same as your
original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle
at the first opportunity.
WHEEL AND WHEEL TRIM CARE
All wheels and wheel trim, especially aluminum
and chrome plated wheels, should be cleaned
regularly using mild (neutral Ph) soap and water to
maintain their luster and to prevent corrosion.
Wash wheels with the same soap solution
recommended for the body of the vehicle, and
remember to always wash when the surfaces are
not hot to the touch.
Your wheels are susceptible to deterioration
caused by salt, sodium chloride, magnesium
chloride, calcium chloride, etc., and other road
chemicals used to melt ice or control dust on dirt
roads. Use a soft cloth or sponge and mild soap to
wipe away promptly. Do not use harsh chemicals or
a stiff brush. They can damage the wheel’s
protective coating that helps keep them from
corroding and tarnishing.
WARNING!
Compact and collapsible spares are for tempo -
rary emergency use only. With these spares, do
not drive more than 50 mph (80 km/h). Tempo -
rary use spares have limited tread life. When the
tread is worn to the tread wear indicators, the
temporary use spare tire needs to be replaced.
Be sure to follow the warnings, which apply to
your spare. Failure to do so could result in spare
tire failure and loss of vehicle control.
WARNING!
Limited use spares are for emergency use only.
Installation of this limited use spare tire affects
vehicle handling. With this tire, do not drive
more than the speed listed on the limited use
spare wheel. Keep inflated to the cold tire
inflation pressures listed on your Tire And
Loading Information Placard located on the
driver’s side B-Pillar or the rear edge of the
driver’s side door. Replace (or repair) the original
equipment tire at the first opportunity and
reinstall it on your vehicle. Failure to do so could
result in loss of vehicle control.
CAUTION!
Avoid products or automatic car washes that use
acidic solutions or strong alkaline additives or
harsh brushes. Many aftermarket wheel
cleaners and automatic car washes may
damage the wheel's protective finish. Such
damage is not covered by the New Vehicle
Limited Warranty. Only car wash soap, Mopar®
Wheel Cleaner or equivalent is recommended.8

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 354.
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.

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!
CAUTION!
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference in
tire size can cause damage to the transfer case.
Tire rotation schedule should be followed to
balance tire wear.8
