carcass.

Carcass: the tire structure, except tread and sidewall rub-
ber which, when inflated, bears the load.

Sidewall: portion of a tire between the tread and bead.

Section width: the linear distance between the exteriors of
the sidewalls of an inflated tire, excluding elevations due
to labeling, decoration, or protective bands.

WA R N I N G
!
Driving with tires that are worn, damaged or
improperly inflated is dangerous.
These type tire conditions will adversely affect vehi-
cle performance.
These type tire conditions can also cause a tread sep-
aration or blowout which may result in an accident
causing serious injury or death.
Tires, including spare tire, degrade over time with
age even when they are not being used. It is recom-
mended that tires over 6 years generally be replaced
even if damage is not obvious.

upon which the tire beads are seated.

Rim diameter: nominal diameter of the bead seat.

Groove: the space between two adjacent tread ribs.Tire Markings
Size Designation
EXAMPLE:P215/65R15

NOTE

European/Japanese metric tire sizing is based on
European/Japanese design standards. Tires designed
to these standards have the tire size molded into the
sidewall beginning with the section width. The letter
“P” is absent from this tire size designation. Exam-
ple: 215/65R15 96H.

LT (Light Truck) -metric tire sizing is based on
U.S.A. design standards. The size designation for
LT-metric tires is the same as for P-metric tires
except for the letters “LT” that are molded into the
sidewall preceding the size designation. Example:
LT235/85R16.


Temporary spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.

Treadwear, Traction and Temperature GradesTreadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a
specified government test course. For example, a tire graded
150 would wear one and one-half (1
1/2) times as well on the
government course as a tire graded 100. The relative perfor-
mance of tires depends upon the actual conditions of their use,
however, and may depart significantly from the norm due to
variations in driving habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B and
C. Those grades represent the tire’s ability to stop on wet pave-
ment as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Temperature
The temperature grades are A (the highest), B and C, represent-
ing the tire’s resistance to the generation of heat and its ability
to dissipate heat when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained high tempera-
ture can cause the material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to sudden tire fail-
ure. The grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the
minimum required by law.
Tire inflation pressures
N00939300105
Proper tire inflation pressure is essential for the safe and satis-
factory operation of your vehicle. The wrong tire pressure will
cause problems in three major areas:

Safety
Too little pressure increases flexing in the tire and can
cause tire failure. Too much pressure can cause a tire to
lose its ability to cushion shock. Objects on the road and
potholes could then cause tire damage that may result in
tire failure.

Economy
The wrong tire pressure can cause uneven wear patterns in
the tire tread. These abnormal wear patterns will reduce
the tread life, and the tire will have to be replaced sooner.
Too little pressure also makes it harder for the tire to roll,
and this uses up more fuel.

Ride comfort and vehicle stability
The superior riding experience built into your vehicle
partly depends on the correct tire pressure. Too much
pressure gives an uncomfortable and jarring ride. Too lit-
tle pressure feels as if your vehicle is slow to respond.
Unequal tire pressures can make steering your vehicle
uneven and unpredictable.
The correct tire pressure for your vehicle is listed on the plac-
ard attached to the sill of the driver’s door.
(Refer to “Tire and loading information placard” on page 9-4.)

The recommended inflation pressures should be used for the
tires listed below.
Tire pressures should be checked, and adjusted if necessary, at
least once a month.
Pressures should be checked more often whenever weather
temperatures change severely, because tire pressures change
with outdoor temperatures. The pressures listed on the placard
are always “cold inflation pressure”.
Cold inflation pressure is measured after the vehicle has been
parked for at least three hours or is driven less than 1 mile
(1.6 km) after having been parked for three hours.
Cold inflation pressure must not go above the maximum values
molded into the tire sidewall. After driving several miles, your
tire inflation pressure may increase 14 to 41 KPA, 2 to 6 PSI
from the cold inflation pressure. Do not let air out of the tires to
get back to the specified cold pressure, or your tire pressure
will be too low.
Check your tires each time you refuel. If one tire looks lower
than the others, check the pressure for all of them.
You should also take the following safety precautions:

Keep your tires inflated to the recommended pressures.
(See the tire and loading information placard attached to
the sill of the driver’s door.)

Stay within the recommended load limits.

Make sure that the weight of any load in your vehicle is
evenly distributed.
Drive at safe speeds.

After filling your tires to the correct pressure, check them
for damage and air leaks. Be sure to replace the caps on
the valve stems.

Replacing tires and wheels
N00939600296
Tire maintenance
N00939700167
The following maintenance steps are recommended:

Check tire pressures regularly.

Have regular maintenance done on the wheel balance and
front and rear suspension alignment.

Rotate your tires regularly as described in the “Tire rota-
tion” section on page 7-26.
CAUTION
!
Avoid using different size tires and wheels from the
ones listed, and avoid the combined use of different
types of tires and wheels. Using different size or type
tires and wheels may affect driving safety.
Refer to “Tires and wheels” on page 9-9.
Even if a wheel has the same rim size and offset as
the specified type of wheel, its shape may prevent it
from being fitted correctly. Consult an authorized
Mitsubishi Motors dealer or a repair facility of your
choice before using wheels that you have.
As your vehicle is equipped with a tire pressure
monitoring system, use only Mitsubishi genuine
wheels.
Other wheels do not permit correct installation of
tire inflation pressure sensors and can cause air
leakage and sensor failure, which would not be cov-
ered by your vehicle’s warranty.
See an authorized Mitsubishi Motors dealer when
you replace a tire or wheel.

Tread wear indicators
N00939800054
Tread wear indicators are built into the original equipment tires
on your vehicle to help you know when your tires should be
replaced. Many states have laws requiring that you replace
your tires at this point.
These indicators are molded into the bottom of the tread
grooves and will appear when the tire tread is worn down to
1/16 inch (1.6 mm).
When the bands appear next to one another in two or more
places, replace your tires. NOTE
Tire wear indicators can have different marks and loca-
tions depending on the tire manufacturer.
Tire rotation
N00939900390
To even out the wear on your tires and make them last longer,
Mitsubishi Motors Corporation recommends that you rotate
your tires at the mileage listed in the “WARRANTY AND
MAINTENANCE MANUAL”.
However, the timing for tire rotation may vary according to
your vehicle condition, road surface conditions, and your own
personal driving habits. Any time you notice unusual wear,
rotate your tires as soon as possible.
When rotating tires, check for uneven wear, damage, and wheel
alignment. Abnormal wear is usually caused by a wrong tire
pressure, wheels that are not aligned properly, wheels that are
out-of-balance, or severe braking.
Check with an authorized Mitsubishi Motors dealer or a repair
facility of your choice to find out the reason for uneven tread
wear.
The first tire rotation is the most important one. It will allow all
your tires to wear evenly.

CAUTION
!
If the tires have arrows (A) indicating the correct
direction of rotation, swap the front and rear tires
on the left-hand side of the vehicle and the front and
rear tires on the right-hand side of the vehicle sepa-
rately. Keep each tire on its original side of the vehi-
cle. When installing the tires, make sure the arrows
point in the direction in which the wheels will turn
when the vehicle moves forward. Any tire whose
arrow points in the wrong direction will not perform
to its full potential.

Snow tires
N00940000362
In some areas of the country, snow tires are required for winter
driving. If snow tires are required in your area, you must
choose snow tires of the same size and type as the original tires
provided with your vehicle. Snow tires should also be installed
on all four wheels. Otherwise your safety and vehicle handling
can be reduced.
Even where laws may permit it, snow tires should not be oper-
ated at sustained speeds over 75 mph (120 km/h).
CAUTION
!
Avoid the combined use of different types of tires.
Using different types of tires can affect vehicle per-
formance and safety.
Front
CAUTION
!
Change to tapered nuts when using snow tires with
steel wheels.
As your vehicle is equipped with a tire pressure
monitoring system, use only Mitsubishi genuine
wheels.
Other wheels do not permit correct installation of
tire inflation pressure sensors and can cause air
leakage and sensor failure, which would not be cov-
ered by your vehicle’s warranty.
See an authorized Mitsubishi Motors dealer when
you replace a tire or wheel.

Waxi n g
N00946000074
Wax your vehicle once or twice a year, or when water does not
bead up on the paint.
Use a soft cloth to put a small amount of wax on the painted
surfaces. After the wax has dried, polish with a dry soft cloth.
Do not wax your vehicle in direct sunlight.
You should wax when the painted surfaces are cool.
Polishing
N00946100017
If painted surfaces have been severely damaged and lost their
original luster and color tone, polish the surface lightly with a
fine polishing compound. Avoid limiting your polishing to the
damaged surface only; polish a somewhat wider area, moving
the polishing cloth in one direction. After polishing, flush the
compound from the surface and apply a coat of wax to regain a
beautiful luster.Damaged paint
N00946200018
Small cracks and scratches in the paint coat should be touched
up as soon as possible with touch-up paint to prevent corrosion.
Check body areas facing the road or the tires carefully for dam-
age to the paint caused by flying stones, etc. The paint code
number for your vehicle can be found on the vehicle informa-
tion code plate in the engine compartment.
CAUTION
!
Waxes containing high abrasive compounds should
not be used. These waxes remove rust and stain
effectively from the paintwork, but are harmful to
the finish of the paint, because they also remove
paint/clearcoat.
They are also harmful to other glossy surfaces such
as the grille, trim, moldings, etc.
Do not use gasoline, kerosene, benzene or paint thin-
ners to remove road tar or other dirt from the vehi-
cle surface.
Do not put wax on the areas having black matte
coating because it can cause uneven discoloration,
patches, blurs, etc. If these get wax on them, wipe
the wax off right away with a soft cloth and warm
water.
On vehicles with sunroof, be careful not to apply any
wax on the weatherstrip (black rubber) when wax-
ing the area around the sunroof opening.
If stained with wax, the weatherstrip cannot main-
tain a weatherproof seal with the sunroof.
