Maintenance
✽ ✽
NOTICE• Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by an
Authorized Kia Dealer.
• Overinflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater pos-
sibility of damage from road haz-
ards. ✽ ✽
NOTICE• Warm tires normally exceed rec-
ommended cold tire pressures by
28 to 41 kPa (4 to 6 psi). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
• Be sure to reinstall the tire infla-
tion valve caps. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leak-
age. If a valve cap is missing,
install a new one as soon as possi-
ble.
Checking tire inflation pres-
sureCheck your tires once a month or
more.
Also, check the tire pressure of the
spare tire.How to checkUse a good quality gage to check tire
pressure. You can not tell if your tires
are properly inflated simply by look-
ing at them. Radial tires may look
properly inflated even when they're
underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1.6 km (1 mile).
WARNING
- Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and lead
to sudden tire failure. This could
result in loss of vehicle control
and potential injury.
WARNING -
Tire pressure
Always observe the following:
Check tire pressure when the
tires are cold. (After vehicle
has been parked for at least
three hours or hasn't been
driven more than 1.6 km (one
mile) since startup.)
Check the pressure of your
spare tire each time you check
the pressure of other tires.
Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
Worn, old tires can cause acci-
dents. If your tread is badly
worn, or if your tires have
been damaged, replace them.

Maintenance26 7Remove the valve cap from the tire
valve stem. Press the tire gage firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gage. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.
Tire rotation To equalize tread wear, it is recom-
mended that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness.
Refer to Section 8, Specifications.
Disc brake pads should be inspected
for wear whenever tires are rotated.Rotate radial tires that have an
asymmetric tread pattern only
from front to rear and not from
right to left.

WARNING
Do not use the temporary
spare tire for tire rotation
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics that could result in death,
severe injury, or property
damage.

Maintenance
Tire replacementIf the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1.6 mm (1/16 inch) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
Compact spare tire replace-
ment (if equipped)A 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 mount-
ing a regular size tire.
Wheel alignment and tire
balance The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.✽ ✽
NOTICEImproper wheel weights can dam-
age your vehicle's aluminum wheels.
Use only approved wheel weights.

Wheel size designation
Wheels are also marked with impor-
tant information that you need if you
ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-
tion mean.
Example wheel size designation:
6.5JX16
6.5 - Rim width in inches.
J - Rim contour designation.
16 - Rim diameter in inches.Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger cars. The speed
rating is part of the tire size designa-
tion on the sidewall of the tire. This
symbol corresponds to that tire's
designed maximum safe operating
speed.
3. Checking tire life (TIN : Tire
Identification Number) Any tires that are over 6 years, based
on the manufacturing date, tire
strength and performance, decline
with age naturally (even unused
spare tires). Therefore, the tires
(including the spare tire) should be
replaced by new ones. You can find
the manufacturing date on the tire
sidewall (possibly on the inside of the
wheel), displaying the DOT Code.
The DOT Code is a series of num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1605 represents
that the tire was produced in the 16th
week of 2005.
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
Z Above 240 km/h (149 mph)
