These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
may vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tires ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
Temperature -A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grades B and A
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by law.WARNING - Tire
temperature
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
build-up and possible sudden
tire failure. This can cause loss
of vehicle control and serious
injury or death.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.

All season tires
KIA specifies all season tires on
some models to provide good per-
formance for use all year round,
including snowy and icy road condi-
tions. All season tires are identified
by ALL SEASON and/or M+S (Mud
and Snow) on the tire sidewall. Snow
tires have better snow traction than
all season tires and may be more
appropriate in some areas.
Summer tires
KIA specifies summer tires on some
models to provide superior perform-
ance on dry roads. Summer tire per-
formance is substantially reduced in
snow and ice. Summer tires do not
have the tire traction rating M+S
(Mud and Snow) on the tire side wall.
if you plan to operate your vehicle in
snowy or icy conditions. KIA recom-
mends the use of snow tires or all
season tires on all four wheels.Snow tires
If you equip your car with snow tires,
they should be the same size and
have the same load capacity as the
original tires. Snow tires should be
installed on all four wheels; other-
wise, poor handling may result.
Snow tires should carry 28 kPa (4
psi) more air pressure than the pres-
sure recommended for the standard
tires on the tire label on the driver's
side of the center pillar, or up to the
maximum pressure shown on the tire
sidewall, whichever is less.
Do not drive faster than 120 km/h (75
mph) when your vehicle is equipped
with snow tires.Radial-ply tires
Radial-ply tires provide improved tread
life, road hazard resistance and
smoother high speed ride. The radial-
ply tires used on this vehicle are of
belted construction, and are selected
to complement the ride and handling
characteristics of your vehicle. Radial-
ply tires have the same load carrying
capacity, as bias-ply or bias belted tires
of the same size, and use the same
recommended inflation pressure.
Mixing of radial-ply tires with bias-ply or
bias belted tires is not recommended.
Any combinations of radial-ply and
bias-ply or bias belted tires when used
on the same vehicle will seriously dete-
riorate vehicle handling. The best rule
to follow is: Identical radial-ply tires
should always be used as a set of four.
Longer wearing tires can be more sus-
ceptible to irregular tread wear. It is
very important to follow the tire rotation
interval shown in this section to
achieve the tread life potential of these
tires. Cuts and punctures in radial-ply
tires are repairable only in the tread
area, because of sidewall flexing.
Consult your tire dealer for radial-ply
tire repairs.

Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
Do not use any abrasive cleaner, pol-
ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
Use only a mild soap or neutral deter- gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
Avoid washing the wheels with high- speed car wash brushes.
Do not use any cleaners containing acid or acid detergents. It may damage
and corrode the aluminum wheels
coated with a clear protective finish.

Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat corro-
sion, we produces vehicles of the highest
quality. However, this is only part of the
job. To achieve the long-term corrosion
resistance your vehicle can deliver, the
owner's cooperation and assistance is
also required.
Common causes of corrosion
The most common causes of corrosion
on your vehicle are:
allowed to accumulate underneath the
vehicle.
Removal of paint or protective coatings by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion.
High-corrosion areas
If you live in an area where your vehicle
is regularly exposed to corrosive materi-
als, corrosion protection is particularly
important. Some of the common causes
of accelerated corrosion are road salts,
dust control chemicals, ocean air and
industrial pollution. Moisture breeds corrosion
Moisture creates the conditions in which
corrosion is most likely to occur. For
example, corrosion is accelerated by
high humidity, particularly when tempera-
tures are just above freezing. In such
conditions, the corrosive material is kept
in contact with the vehicle surfaces by
moisture that evaporate slowy.
Mud is particularly corrosive because it
dries slowly and holds moisture in con-
tact with the vehicle. Although the mud
appears to be dry, it can still retain the
moisture and promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be dis-
persed. For all these reasons, it is partic-
ularly important to keep your vehicle
clean and free of mud or accumulations
of other materials. This applies not only
to the visible surfaces but particularly to
the underside of the vehicle.
