The temperature grades are A (the highest), B and C, representing the tire’s resistance to thegeneration of heat and
its ability to dissipate
heat when tested under controlled conditions on a specified indoor la
boratory test wheel.
Sustained high temper
ature can cause the
material of the tire to
degenerate and reduce
tire life, and excessive temperature can leadto sudden tire failure. The grade C corre- sponds to a level of performance which all passenger car tires must meet under the Fed- eral Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels ofperformance on the labora
tory test wheel than
the minimum required by law.

Proper tire inflation pres
sure is essential for
the safe and satisfactory 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 muchpressure can cause a tire to lose its ability to cushion shock. Objects on the road and potholes could then cause tire damage thatmay result in tire failure.
Economy The wrong tire pressu
re can cause uneven
wear patterns in the tire tread. These abnormal wear patter
ns will reduce the
tread life, and the tire will have to bereplaced 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 e
xperience built into
your vehicle partly depends on the correct tire pressure. Too much pressure gives an uncomfortable and ja
rring ride. Too little
pressure feels as if
your vehicle is slow to
respond. Unequal tire pressure
s can make steering
your vehicle uneven and unpredictable.
The tire pressure for your vehicle under nor- mal driving conditions is listed on the placard attached to the driver’s door sill.(Refer to “Tire and loading information plac- ard” on page 11-3.) The recommended infl
ation pressures under
normal driving conditions 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, becaus
e tire pressures change with
outdoor temperatures. The pressures listed are always “cold in
flation pressure”.
Cold inflation pressure is measured after thevehicle 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 side-wall. After driving seve
ral miles, your tire
inflation pressure may increase 2 to 6 psi (14 to 41 kPa) from the cold inflation pressure.Do not let air out of the tires to get back to the specified cold pressure, or your tires 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 pre- cautions:

To even out the wear on your tires and make them last longer, Mitsubishi Motors Corpora- tion recommends that y
ou rotate your tires at
the mileage listed in the “WARRANTY AND MAINTENANCE MANUAL”. However, the timing for tire rotation mayvary according to your vehicle condition, road surface conditions, and your own per- sonal driving habits. Any time you notice unusual wear, rotate your tires as soon as pos- sible. When rotating tires, check for uneven wear, damage, and wheel alignment. Abnormal wear is usually caused by a wrong tire pres- sure, wheels that ar
e not aligned properly,
wheels that are out-of-balance, or severe braking. Check with an author
ized 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.

In some areas of the country, snow tires are required for winter driving. If snow tires are required in your area, you must choose snowtires of the same size
and type as the original
tires provided with your vehicle. Snow tires should also be installe
d on all four wheels.
Otherwise your safety and vehicle handling can be reduced. Even where laws may permit it, snow tiresshould not be operated
at sustained speeds
over 75 mph (120 km/h).
Tire rotation
CAUTION A compact spare tire can be installed tempo- rarily in place of a tire
that has been removed
during the tire rotation. However, it must notbe included in the regular tire rotation sequence. If the tires have arrows (A) indicating the correct direction of ro
tation, swap the front
and rear tires on the le
ft-hand side of the
vehicle and the front
and rear tires on the
right-hand side of th
e vehicle separately.
Keep each tire on its original side of the vehicle. When installing the tires, make surethe arrows point in the
direction in which the
wheels will turn when the vehicle moves for- ward. Any tire whose arrow points in thewrong direction will not
perform to its full
potential.

CAUTION Avoid the combined use of different types of tires. Using different t
ypes of tires can affect
vehicle performance and safety.
