2006 KIA Optima wheel size

5-9
 If you believe you may have gottenyour brakes wet, apply them lightly
while driving until normal braking
operation returns.WINTER DRIVING We recommend that you carryemergency equipment. Some things
you might include are tire chains, a
window scraper, windshield de-icer,
a bag of sand or salt, flares, a small
shovel and jumper cables.
 Make sure you have sufficient ethylene glycol coolant in the
radiator.
 Check the battery condition and cables. Cold temperatures reduce the
capacity of any battery, so it must be
in top shape to provide enough
winter starting power.
 Make sure the engine oil viscosity is suitable for cold weather.
 Check the ignition system for loose connections and damage.  Use antifreeze-formulated windshield
washer fluid and make sure you have
sufficient fluid for your trip. (Do not
use engine coolant antifreeze.)
 Do not use the parking brake if it might freeze. This is most likely to
happen after driving in slushy or wet
conditions and temperatures drop into
the freezing range. When parking,
shift to P (Park) with automatic
transaxle, or to 1 (First) or R
(Reverse) with a manual transaxle
and block the rear wheels.
SNOW TIRESWhen snow tires are used, select the size
and construction specified on the Tire
Pressure Label. It is strongly
recommended that snow tires be used on
all four wheels, or poor handling may
result. Snow tires should not be operated
at speeds exceeding 120 km/h (75 mph).
These tires should be inflated 4 psi (28
kPa, 0.3 kg/cm
2) above the recommended pressures shown on the Tire
Specification/Pressure Label, but inflation
should never exceed the maximum cold-
tire pressure shown on the tire sidewalls.
Do not install studded tires without first
checking local, provincial and municipal
regulations for possible restrictions
against their use.
WARNING - Snow Tire
Size
Snow tires should be
equivalent in size and type to
the vehicle’s standard tires.
Otherwise, the safety and
handling of your vehicle may be
adversely affected.

DRIVING TIPS
5-10TIRE CHAINSTire Chain SelectionRegulations regarding the use of tire
chains vary according to location or type
of road, so always check them before
installing chains.
Use only SAE Class “S” tire chains.
Chains must be the proper size for the
vehicle, as recommended by the chain
manufacturer.CHAIN INSTALLATIONWhen installing chains on your tires,
carefully follow the instructions of the
chain manufacturer.
The chain bands will scratch the wheel
covers. Remove the covers before
installing the chains.Install the chains on the front tires as
tightly as possible. The use of chains on
the rear tires is not recommended.
Retighten the chains after driving 0.5-1.0
km (1/4-1/2 mile).
Driving in Flooded AreasAvoid driving through flooded areas
unless you are sure the water is no higher
than the bottom of the wheel rims. Drive
through any water slowly. Allow
adequate stopping distance because
brake performance may be affected.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
WARNING - Tire Chains
 The use of chains may
adversely affect vehicle
handling.
 Do not exceed 30 mph (50 km/
h) or the chain manufacturer’s
recommended speed limit,
whichever is lower.
 Drive carefully and avoid
bumps, holes, sharp turns
and other road hazards,
which may cause the vehicle
to bounce.
 Avoid sharp turns or locked
wheel braking.
 Do not attempt to use a tire
chain on the temporary spare
tire because it may impair
vehicle handling and result in
damage to the vehicle and the
tire.

6-21  Do not take this vehicle through an
automatic car wash with the compact
spare tire installed.
 Do not use tire chains on this tire.
Because of the smaller size, a tire
chain will not fit properly. This could
damage the vehicle and result in loss
of the chain.
 This tire should not be installed on
the front axle if the vehicle must be
driven in snow or on ice.
 Do not use the compact spare tire on
any other vehicle because this tire
has been designed especially for your
vehicle.
 The compact spare’s tread life is
shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn compact
spare tires with the same size and
design, mounted on the same wheel.

MAINTENANCE
7-28COMPACT SPARE TIRE
REPLACEMENTA compact spare tire has a shorter tread
life than a regular size tire. Replace it
when you can see the tread wear indicator
bars on the tire. The replacement compact
spare tire should be the same size and
design tire as the one provided with your
new Kia and should be mounted on the
same compact spare tire wheel. The
compact spare tire is not designed to be
mounted on a regular size wheel, and the
compact spare tire wheel is not designed
for mounting a regular size tire.
WHEEL ALIGNMENT AND
TIRE BALANCEIn addition to proper tire inflation,
correct wheel alignment helps to
minmize tire wear. Your vehicle’s
alignment should be checked every 12
months or 24,000 km (15,000 miles).
Your tires were properly balanced at the
factory, but they may need to be
rebalanced before they wear out. If you
notice a consistent vibration when
driving, have your Kia Dealer inspect
your tires. A tire should always be
rebalanced if it has been removed from
the wheel.

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.
