CChecking tire inflation pressureCheck 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). Remove 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.
•
Inspect your tires frequently for
proper inflation as well as wear
and damage. Always use a tire
pressur e gauge.
•
Tires with too much or too little
pressure wear unevenly causing
poor handling, loss of vehicle
control, and sudden tire failure
leading to accidents, injuries,
and even death. The recom-
mended cold tire pre ssure for
your vehicle can be found in this
manual and on the tire label
located on the driver's side ce n-
ter pillar.
•
Worn tires can cause accidents.
Replace tires that are worn,
show uneven wear, or are dam-
aged.
•
Remember to check the pres-
sure of your spare tire.
HYUNDAI recommends that you
check the spare every t ime you
check the pressure of the other
tires on your vehicle.
WARNING

1.(%,204/3424-3TTire rotation To equalize tread wear, it is recom-
mended that the tires be rotated
every 10,000 km (6,200 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 “Tire and wheels” in chapter
8. Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
Rotate radial tires that have an asym-
metric tread pattern only from front
to rear and not from right to left.i•
Do not use the compact spare
tire for tire rotation.
•
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling ch aracteristics that
could result in death, severe
injury, or property damage.

WWheel alignment and tire bal-
ance 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.Improper wheel weights can damage
your vehicle's aluminum wheels. Use
only approved wheel weights.
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.
When replacing the tires, recheck
and tighten the wheel nuts after driv-
ing about 1,000 km (620miles). If the
steering wheel shakes or the vehicle
vibrates while driving, the tire is out
of balance. Align t he tire balance. If
the problem is not solved, we recom- mend that you contact an authorizedHYUNDAI dealer.NOTICE

Tread wear indicator
Replacing tires
To reduce the chance or serious
or fatal injuries from an accident
caused by tire failure or loss of
vehicle control:•
Replace tires that are worn,
show uneven wear, or are dam-
aged. Worn tires can cause loss
of braking ef fectiveness, steer-
ing control, and traction.

WARNING

1.(),204/3424-3
CCompact spare tire replacement
(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 replaced 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 to mount a
regular size tire.
(Continued)•
Do not drive your vehicle with
too little or too much pressure in
your tires. This can lead to
uneven we ar and tire failure.
•
When replacing tires, never mix
radial and bias-ply tires on the
same car. You must replace all
tires (i ncluding the spare) if mov-
ing from radial to bias-ply tires.
•
It is best to replace all four tires at
the same time. If that is not possi-
ble, or necessary, then re place the
two front or two rear tires as a pair.
Replacing just one tire can serious-
ly affect your veh icle’s handling.
•
Using tires and wheel other than
the recommended sizes could
cause unusual handling charac-
teristics an d poor vehicle con-
trol, resulting in a serious acci-
dent.
(Continued)
(Continued)
•
Wheels that do not meet
HYUNDAI's specifications may
fit poorly and result in damage to
the vehicle or u nusual handling
and poor vehicle control.
•
The ABS works by comparing
the speed of the wheels. Tire
size can affect wheel speed.
When replacing ti res, all 4 tires
must use the same size original-
ly supplied with the vehicle.
Using tires of a differe nt size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregu -
larly. (if equipped)

WWheel 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.
Tire tractionTire 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. Slow down whenever there
is rain, snow or ice on the road, to
reduce the possibility of losing con-
trol of the vehicle.Tire maintenance In addition to proper inflation, correct
wheel alignment helps decrease tire
wear. If you find a tire 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.
Tire sidewall labelingThis information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tire in
case of a recall.1. Manufacturer or brand nameManufacturer or Brand name is
shown.
A wheel that is not the correct size
may adversely affect wheel and
bearing life, braking and stopping
a bilities, handling characteristics,
ground clearance, body-to-tire
clearance, snow chain clearance,
spee dometer and odometer cali-
bration, headlight aim and bumper
height.

1.(#,204/3424-322. 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.)P195/65R15 94HP - 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).
195 - Tire width in millimeters.
65 - Aspect ratio. The tire’s chapter height as a percentage of its
width.
R - Tire construction code (Radial).
15 - Rim diameter in inches. 94 - 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 chapter
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:6.0JX156.0 - Rim width in inches.
J - Rim contour designation.
15 - Rim diameter in inches.
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.

33. 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 OOOOThe 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 1618 represents
that the tire was produced in the 16th
week of 2018.
4. Tire ply composition and materi- alThe 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 inflationpressureThis 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.
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 conditions can accel-
erate the aging process. Failure
to follow this warning could cause
sudden tire failure, which could lead to a loss of control and an
accident inv olving serious injury or
death.
WARNING

1.(',204/3424-366. Maximum load ratingThis 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 chapter width.
For example:
TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wearThe 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 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
braking traction tests, and does
not include acceleration, corner-
ing, hydroplaning, or peak traction
characteristics.
WARNING

1.(1
,204/3424-3
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. Grades B and A
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by law.
LLow aspect ratio tire
(if equipped) Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided
for sporty looks.
Because the low aspect ratio tires
are optimized for handling and brak-
ing, it may be more uncomfortable to
ride in and there is more noise com-
pare with normal tires.
Tire temperature
The temperature grade for this tire
is established for a tire that is
properly inflated and not over-
loaded. Excessive speed, under-
inflation, or excessive loading,
either separately or in combina-
tion, can cause heat build-up and
sudden tire failure. This can cause
loss of vehicle control a nd serious
injury or death.
WARNING

1.#,204/3424-3
BB ecause the sidewall of the low
aspect ratio tire is shorter than the
normal, the wheel and tire of the low
aspect ratio tire is easier to be dam-
aged. So, follow the instructions
below.
- When driving on a r ough road or
off road, drive cautiously because
tires and wheels may be damaged.
And after driving, insp ect tires and
wheels.
- When passing over a pothole, speed bump, manhole, or curb
stone, drive slowly so that the tires
and wheels are not damaged.
- If the tire is impacted, we recom- mend that you inspect the tire con-
dition or contact an authorized
HYUNDAI dealer.
- To prevent damage to the tire, inspect the t ire condition and pres-
sure every 3,000km. • It is not easy to recognize the tire
damage with your own e yes. But if
there is the slightest hint of tire
damage, even though you cannot
see the tire damage with your own
eyes, have the tire checked or
replaced because the tire damage
may cause air leakage from the
t ire.
• If the tire is damaged by driving on a rough road, off road, pothole,
manhole, or curb stone, it will not
be covered by the warranty.
• You can find out the tire informa- tion on the tire sidewall.
