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 per-
missible inflation pressure. Refer to
the Tire and Loading Information label
for recommended inflation pressure.
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.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 440
TRACTION A
TEMPERATURE A 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 (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.
Tires degrade over time, even when
they are not being used. Regardless
of the remaining tread, we recom-
mend that tires be replaced after
approximately six (6) years of normal
service. Heat caused by hot climates
or frequent high loading conditions
can accelerate the aging process.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
may vary with respect to grade.

ed.
Sidewall: The portion of a tire
between the tread and the bead. 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.
Tread: 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 1/16 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 150 lbs. (68kg) plus the

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.
WARNING
Do not use summer tires at tem-
peratures below 45°F (7°C) or
when driving on snow or ice. At
temperatures below 45°F (7°C),
summer tires can lose elastici-
ty, and therefore traction and
braking power as well. Change
the tires on your vehicle to win-
ter or all-weather tires of the
same size as the standard tires
of the vehicle. Both types of
tires are identified by the M+S
(Mud and Snow) marking. Using
summer tires at very cold tem-
peratures could cause cracks to
form, thereby damaging the
tires permanently.

Maintenance
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 4 psi (28
kPa) 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 75 mph (120
km/h) when your vehicle is equipped
with snow tires.
Tire chains
Tire chains, if necessary, should be
installed on the front wheels.
Be sure that the chains are installed
in accordance with the manufactur-
er's instructions.
To minimize tire and chain wear, do
not continue to use tire chains when
they are no longer needed.
When driving on roads coveredwith snow or ice, drive at less than
20 mph (30 km/h).
Use the SAE “S” class or wire chains.
If you hear noise caused by chains contacting the body, retighten the
chain to avoid contact with the
vehicle body.
To prevent body damage, retighten the chains after driving 0.3~0.6
miles (0.5~1.0 km).
Do not use tire chains on vehicles equipped with aluminum wheels.
In unavoidable circumstances, use
a wire type chain.
Use wire chains less than 0.47 inches (12 mm) to prevent damage
to the chain’s connection.
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 select-
ed to complement the ride and han-
dling 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.

CAUTION
When replacing tires, use the same size originally supplied with the vehicle. Using tires of a different size can damage the related parts or make them work irregularly.
✽ ✽ NOTICE
• It is permissible to add 3psi to the standard tire pressure specification if colder temperatures are expected soon.
Tires typically loose 1psi for every 12°F temperature drop. If extreme temperature variations are expected, re-
check your tire pressure as necessary to keep them properly inflated.
• We recommend that when replacing tires, use the same originally supplied with the vehicles. If not, that aff\
ects driving performance.
• When driving in high altitude grades, it is natural for the atmospheric pressure to decrease. Therefore, please check the tire pressure and add more air when necessary.
Additionally required tire air pressure per km above sea level: 1.5psi/km
