Tire inflation pressures
N00939300802
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 driver’s door sill.
(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 driver’s door sill.)
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 reinstall the caps on
the valve stems.
Replacing tires and wheels
N00939600397
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 9-8.Always use tires of the same size, same type, and
same brand, and which have no wear differences.
Using tires that differ in size, type, brand or the
degree of wear, will increase the differential oil tem-
perature, resulting in possible damage to the driving
system. Further, the drive train will be subjected to
excessive loading, possibly leading to oil leakage,
component seizure, or other serious problems.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.

8-2 Customer assistance/Reporting Safety Defects
8Consumer information (For vehicles sold in
U.S.A.)
N01047100100
This information is provided in compliance with the require-
ments of the National Highway Traffic Safety Administration,
Department of Transportation. It provides the purchasers
and/or prospective purchasers with information on reporting
safety defects. Uniform tire quality gradingDOT quality grades - All passenger vehicle tires must conform
to Federal Safety Requirements in addition to these grades. The
specific grade rating in each grade category is shown on the
side wall of the tires on your vehicle. Treadwear 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 AA, A, B, C 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 A, B, CThe 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.
WA R N I N G
!The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
WA R N I N G
!The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
