TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire infla-
tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
1.6 km (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tires and wheels” in chapter
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
WARNING - Tire underin-
flation
Inflate your tires consistent with
the instructions provided in this
manual. Severe underinflation
(70 kPa (10 psi) or more) can
lead to severe heat build-up,
causing blowouts, tread separa-
tion and other tire failures that
can result in the loss of vehicle
control. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Tire replacement
If the tire is worn evenly, a tread wear
Indicator (A) 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.The ABS works by comparing the
speed of the wheels. The tire size
affects wheel speed. When replacing
tires, all 4 tires must use the same
size originally supplied with the vehi-
cle. Using tires of a different size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregularly.
✽ ✽

NOTICE
• We recommend that when replac-
ing tires, use the same which were
originally supplied with the vehi-
cle. If not, driving performance
could be altered.
• When replacing tires (or wheels),
it is recommended to replace the
two front or two rear tires (or
wheels) as a pair.
Replacing just one tire can serious-
ly affect your vehicle's handling.
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.
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 clear-
ance, snow chain clearance,
speedometer and odometer calibra-
tion, 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.)
P205/55R16 89H
P - Applicable vehicle type (tires
marked with the prefix “P’’ are
intended for use on passenger
vehicles or light trucks; however,
not all tires have this marking).
205 - Tire width in millimeters.
55 - Aspect ratio. The tire’s section
height as a percentage of its
width.
R - Tire construction code (Radial).
16 - Rim diameter in inches.
89 - Load Index, a numerical code
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.
Example wheel size designation:
6.0JX16
6.0 - 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 vehicles. 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 : Tire
Identification 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 1620 represents
that the tire was produced in the 16th
week of 2020.
4. Tire ply composition and mate-
rial
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
Replace tires within the recom-
mended time frame. Failure to
replace tires as recommended
can result in sudden tire failure,
which could lead to a loss of
control and an accident.

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.

755
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 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 vehicle 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 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.WARNING
Do not use summer tires at tem-
peratures below 7°C (45°F) or
when driving on snow or ice. At
temperatures below 7°C (45°F),
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.

Specifications, Consumer information and Reporting safety defects
✽ ✽
NOTICE
• It is permissible to add 21 kPa (3 psi) to the standard tire pressure specification if colder temperatures are expect-
ed soon.
Tires typically loose 7 kPa (1 psi) for every -11°C (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 affects
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: 10.5 kPa (1.5psi)/km
