TIRE SIZE DESIGNATIONA tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replacement
tires for your car. The following explains
what the letters and numbers in the tire
size designation mean.
Example tire size designation :
P205/60R15 82T
P- Applicable vehicle type (tires marked
with the prefix “P” are intended for use
on passenger cars; however, not all tires
have this marking).
205- Tire width in millimeters.
60- Aspect Ratio. The tire’s section
height as a percentage of tire width.
R- Tire construction code (radial).
15- Rim diameter in inches.
82- Load Index: A numerical code
associated with the maximum load the
tire can carry.
T- Speed Rating symbol. See the speed
rating chart in this section for additional
information.
✻
NOTICE
• When replacing tires, never mix
radial, bias-belted, and bias-type
tires. All four tires should be of
the same size, design and
construction. Use only the tire
sizes listed on the Tire Label
attached to the passenger’s door.
Make sure that all tires and
wheels are the same size and
have the same load-carrying
capacity. Use only tire and wheel
combinations recommended on
the Tire Label or by an
Authorized Kia Dealer. Failure
to follow these precautions can
adversely affect the safety and
handling of your vehicle.
• The use of any other tire size or
type may seriously affect ride,
handling, ground clearance, tire
clearance, and speedometer
alibration.
• Driving on worn-out tires is very
hazardous and will reduce
braking effectiveness, steering
accuracy, and raction.
• It is best to replace all four tires
on your vehicle at the same time.
If that is not possible, then
replace the two front or two rear
tires as a pair.
Replacing just one tire can
seriously affect vehicle handling.

7-30WHEEL SIZE DESIGNATIONWheels are also marked with important
information that you need if you ever
need to replace one. The following
explains what the letters and numbers in
the wheel size designation mean.
Example wheel size designation: 15 X 6J
15 - Rim diameter in inches.
6 - Rim width in inches.
J - Rim contour designation.TIRE SPEED RATINGSThe following chart below shows many
of the different speed ratings currently
used for passenger car tires. The speed
rating symbol is part of the tire size
designation on the sidewall of the tire.
This symbol corresponds to that tire’s
designed maximum safe operating speed.
UNIFORM TIRE QUALITY
GRADINGThe following information relates to the
tire grading system developed by the
Canadian Motor Vehicle Safety Standard
(CMVSS) for grading tires by tread wear,
traction and temperature performance.These temperature grades are molded on
the sidewalls of passenger vehicle tires.
Tires available as standard or optional
equipment on Kia vehicles may vary
with respect to grade.

CAUTION
A wheel that is not the correct size
may adversely affect wheel and
bearing life, braking and stopping
abilities, handling characteristics,
ground clearance, body-to-tire
clearance, snow chain clearance,
speedometer calibration, headlight
aim and bumper height.
WARNING - Halogen
Bulbs

Wear eye protection when
changing a bulb. Allow the
bulb to cool before handling it.
Halogen bulbs contain
pressurized gas. If broken, a
halogen bulb will explode and
will produce flying pieces of
glass.
Always handle halogen bulbs
carefully to avoid scratches
and abrasions. If the bulbs
are lit, avoid contact with
liquids. Never touch the
glass with bare hands.
Residual oil may cause the
bulb to overheat and burst
when lit. A bulb should be
operated only when installed
in the headlight assembly.
If a bulb becomes damaged
or cracked, replace it
immediately and carefully
dispose it.
