Compact spare tire replacement
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 vehicle 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 replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
G200800AUN
Tire traction
Tire 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 possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
G200900AUN
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 alignment.
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.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,
speedometer and odometer cal-
ibration, headlight aim and
bumper height.

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.)
P215/50R17 95H
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).
215 - Tire width in millimeters.
50 - Aspect ratio. The tire’s section height as a percentage of its
width.
R - Tire construction code (Radial).

associated with the maximum
load the tire can carry.
H - Speed Rating Symbol. See the speed rating chart in this section
for additional information.
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.

Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger car tires. The
speed rating is part of the tire size
designation on the sidewall of the
tire. This symbol corresponds to that
tire's designed maximum safe oper-
ating speed.

3. Checking tire life (TIN : TireIdentification Number)
Any tires that are over 6 years old,
based on the manufacturing date,
(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 1608 represents
that the tire was produced in the 16th
week of 2008.

4. Tire ply composition and material
The 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.
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)

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 condi-
tions 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 acci-
dent involving serious injury or
death.

5. Maximum permissible inflation
pressure
This 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.
G201006AUN
6. Maximum load rating
This 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.
G2010007AEN-EC
7. Uniform tire quality grading
Tread wear
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example: TREAD wear 200
TRACTION AA
TEMPERATUE A
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 (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to 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 your vehicle
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 tire’s 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.
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.

Speed Rating: An alphanumeric
code assigned to a tire indicating the
maximum speed at which a tire can
operate.
Traction: The friction between the
tire and the road surface. The
amount of grip provided.
Tr e a d: The portion of a tire that
comes into contact with the road.
Treadwear Indicators: Narrow
bands, sometimes called "wear
bars," that show across the tread of a
tire when only 2/32 inch of tread
remains.
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 68 kg (150 lbs.) 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
maximum occupant and cargo
weight.
Vehicle Normal Load on the Tire
:
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 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 car is equipped with
snow tires.Radial-ply tires
Radial-ply tires provide improved
tread life, road hazard resistance and
smoother high speed ride. The radi-
al-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 combina-
tions of radial-ply and bias-ply or bias
belted tires when used on the same
vehicle will seriously deteriorate
vehicle handling. The best rule to fol-
low is: Identical radial-ply tires should
always be used as a set of four.
Longer wearing tires can be more
susceptible 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.
