•• Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformatio n also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, we recommend that the
system be checked by an author-
ized HYUNDAI dealer.
• Overinflation produces a harsh ride, excessive wear at the center
of the tire tread, and a greater pos-
sibility of damage from roa d haz-
ards. • Warm tires normally exceed rec-
ommended cold tire pressures by
28 to 41 kPa (4 to 6 psi). 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
val ve 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 tires are cold. (After vehicle has been
parked for at least three hours or
hasn't been driven more than 1.6
km (one mile) since startup.)
• C heck 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.
• Worn, old tires can cause acci-
dents. If your tread is badly worn,
or if your tires have been dam-
aged , replace them.

Tire Inflation
Overinflation or underinflation can
reduce tire life, adversely affect
vehicle handling, and lead to sud-
den tire failure. This could result in
loss of vehicle control and poten-
tial injury.

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.

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.

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.

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.

• Only steel wheel provided as a spare wheel with all variants of vehicle.
• Spare tire make can be from any tire manuafacturer i.e. Bridgestone/MRF/Apollo.
• It is permissible to add 20 kPa (3 psi) to the standard tire pressure specification if colder temperatures are expect\b
ed soon. Tires typically lose 7 kPa (\f psi) for every 7°C (\f2°F) temperature drop. If extreme temperature variations
are expected, rec
heck your tire pressure as necessary to keep them properly inflated.
• An air pressure generally decreases, as you drive up to a high\baltitude area above sea level. Thus, if you plan to drive a high\baltitude area, check the tire pressures in advance. If necessary, inflate them to a proper level (Air infla\b
tion per altitude: +\f0 kPa/\f km (+2.4 psi/\f mile).
