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 mile (1.6 km).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire 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.OUB071018
WARNING
- Checking the tire inflation
pressure
Inflate your tires consistent with
the instructions provided in this
manual.
Regularly check the tire infla-
tion pressure, and correct it as
needed: at least twice a month
and before a long trip.
If you fail to observe this pre-
caution, you may be driving on
tires with incorrect tire pres-
sures, a condition that may not
only compromise your vehicle's
driving stability, but also lead to
tire damage and the risk of an
accident.
This risk is much higher on hot
days and when driving for long
periods at high speeds.

Maintenance
 Underinflation also results inexcessive 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.
 Warm tires normally exceed rec- ommended cold tire pressures by 4
to 6 psi (28 to 41 kPa). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
 Be sure to reinstall the tire inflation valve caps. Without the valve cap,
dirt or moisture could get into the
valve core and cause air leakage. If
a valve cap is missing, install a
new one as soon as possible.Tire pressure
Always observe the following:
 Check tire pressure when the tiresare cold. (After vehicle has been
parked for at least three hours or
hasn't been driven more than 1
mile (1.6 km) since startup.)
 Check the pressure of your spare tire each time you check the pres-
sure of other tires.
 Never overload your vehicle. Be careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
Checking tire inflation pres-
sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gauge to check
tire pressure. You cannot tell if your
tires are properly inflated simply by
looking 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 mile (1.6 km).
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.

Remove the valve cap from the tire
valve stem. Press the tire gauge 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 gauge. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.  Inspect your tires frequently for
proper inflation as well as wear and
damage. Always use a tire pres-
sure gauge.
 Tires with too much or too little pressure can cause tires to wear
unevenly, causing poor handling,
loss of vehicle control, and sudden
tire failure leading to accidents,
injuries, and even death. The rec-
ommended cold tire pressure for
your vehicle can be found in this
manual and on the tire label locat-
ed on the driver's side center pillar.
 Remember to check the pressure of your spare tire. Kia recommends
that you check the spare every
time you check the pressure of the
other tires on your vehicle.Tire rotation
To equalize tread wear, it is recom-
mended that the tires be rotated
every 8,000 miles (13,000 km) 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 the 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 “Tire and wheels” in chapter
8.

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 1/16 inch (1.6 mm)
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.
• It is best to replace all four tires at the same time. If that is not possi-
ble, or necessary, then replace the
two front or two rear tires as a pair.
Replacing just one tire can serious-
ly affect your vehicle's handling.
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.

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 1621 represents
that the tire was produced in the 16th
week of 2021.
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.
5. Maximum permissible inflationpressure
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 200
Traction AA
Temperature A
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.

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.
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tires 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.
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction char-
acteristics.

Maintenance
Temperature -A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.Tire terminology and definitions
