Maintenance
Tire maintenance In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignement.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.Tire tractionTire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. To reduce the possiblity of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tire sidewall labelingFederal law requires tire manufactur-
ers to place standardized information
on the sidewall of all tires. This infor-
mation identifies and describes the
fundamental characteristics of the
tire and also provides the tire identifi-
cation number (TIN) for safety stan-
dard certification. The TIN can be
used to identify the tire in case of a
recall.1. Manufacturer or brand nameManufacturer or Brand name is
shown.
2. Tire size designation A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replace-
ment tires for your car. The following
explains what the letters and num-
bers in the tire size designation
mean.
Example tire size designation:
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.)
P205/60R16 92H
P - Applicable vehicle type (tires
marked with the prefix “P’’ are
intended for use on passenger
cars or light trucks; however, not
all tires have this marking).
205 - Tire width in millimeters.
60 - Aspect ratio. The tire’s section
height as a percentage of its
width.
R - Tire construction code (Radial).
16 - Rim diameter in inches.

4. Tire ply composition and mate-
rialThe number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible inflation
pressureThis number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.6. Maximum load ratingThis number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.7. Uniform tire quality grading The following information relates to
the tire grading system developed by
the Canada Motor Vehicle Safety
Stardard (CMVSS) for grading tires
by tread wear, traction and tempera-
ture performance.Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use. However, performance
may differ from the norm because of
variations in driving habits, service
practices and differences in road
characteristics and climate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on Kia vehicles
may vary with respect to grade.
WARNING -
Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires generally be replaced after
six (6) years of normal service.
Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging
process. Failure to follow this
warning can result in sudden tire
failure, which could lead to a
loss of control and an accident
involving serious injury or death.

Maintenance32 7Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. The
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. The grades repre-
sent the tire’s resistance to the gen-
eration of heat and its ability to dissi-
pate heat when tested under con-
trolled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can
cause the material of the tires to
degenerate and reduce tires life, and
excessive temperature can lead to
sudden tires failure. Grades A and B
represent higher levels of perform-
ance on the laboratory test wheel than
the minimum required by the law.
Tire terminology and defini-
tionsAir Pressure: The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
kilopascal (kPa) or pounds per
square inch (psi).
Accessory Weight: This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic transmis-
sion, power seats, and air condition-
ing.
Aspect Ratio: The relationship of a
tire's height to its width.
Belt:A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead: The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire: A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread.
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.

built up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings: The DOT code

UTQGS: Uniform Tire Quality
Grading Standards, a tire information
system that provides consumers with
ratings for a tire's traction, tempera-
ture and treadwear. Ratings are
determined by tire manufacturers
using government testing proce-
dures. The ratings are molded into
the sidewall of the tire.
Vehicle Capacity Weight: The num-
ber of designated seating positions
multiplied by 150 lbs. (68 kg) plus the
rated cargo and luggage load.Vehicle Maximum Load on the
Tire: Load on an individual tire due to
curb and accessory weight plus

Vehicle Normal Load on the Tire:
That load on an individual tire that is
determined by distributing to each
axle its share of the curb weight,
accessory weight, and normal occu-
pant weight and driving by 2.
Vehicle Placard: A label permanent-
ly attached to a vehicle showing the
original equipment tire size and rec-
ommended inflation pressure.
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 tiresIf 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
pressure recommended for the stan-
dard tires on the tire label on the dri-
ver'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 car is equipped with
snow tires.
