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 153.
NOTE:Under a maximum loaded vehicle condition, Gross
Axle Weight Ratings (GAWRs) for the front and rear
axles must not be exceeded Ú page 153.
To determine the maximum loading conditions of
your vehicle, locate the statement “The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs” on the Tire and Loading
Information placard. The combined weight of
occupants, cargo/luggage and trailer tongue
weight (if applicable) should never exceed the
weight referenced here.

it is not designed to be reused when driven under
a Run Flat mode 14 psi (96 kPa) condition.
NOTE:TPMS sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended to drive a vehicle loaded at
full capacity or to tow a trailer while a tire is in the
Run Flat mode.
For more information Ú page 201.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions,
do not spin your vehicle's wheels above 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping Ú page 262.
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 1/16 of an inch (1.6 mm).
When the tread is worn to the tread wear
indicators, the tire should be replaced
Ú page 309.
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:The Wheel Valve Stem must be replaced as well
when installing new tires due to wear and tear in
existing tires.
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 — Worn Tire
2 — New TireWARNING!

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.

22_MP_OM_EN_USC_t.book Page 308

310SERVICING AND MAINTENANCE
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 252.
For restrictions when towing with a spare tire
designated for temporary emergency use
Ú page 157.
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
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.

compact spare tire and wheel on the vehicle at any
given time.
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.
SNOW TRACTION DEVICES
Use of traction devices require sufficient
tire-to-body clearance. Due to limited clearance,
the following snow traction devices are
recommended. Follow these recommendations to
guard against damage:
Snow traction device must be of proper size for
the tire, as recommended by the snow traction
device manufacturer.
No other tire sizes are recommended for use
with the snow traction device.
Please follow the table below for the recom -
mended tire size, axle and snow traction device:
WARNING!

Compact and collapsible spares are for temporary
emergency use only. With these spares, do not
drive more than 50 mph (80 km/h). Temporary
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.

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 268.
The reasons for any rapid or unusual wear should
be corrected prior to rotation being performed. The suggested rotation method is the “forward
cross” shown in the following diagram. This
rotation pattern does not apply to some directional
tires that must not be reversed.

Tire Rotation (Forward Cross)

CAUTION!
To avoid damage to your vehicle or tires, observe
the following precautions:

Because of restricted traction device clearance
between tires and other suspension compo -
nents, it is important that only traction devices
in good condition are used. Broken devices can
cause serious damage. Stop the vehicle imme -
diately 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 power transfer
unit. Tire rotation schedule should be followed to
balance tire wear.
