WARNING
Recommended pressures must be
maintained for the best ride, vehicle
handling, and minimum tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and lead to
sudden tire failure that could result
in loss of vehicle control resulting in
an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result in
the loss of vehicle control resulting
in an accident. This risk is much
higher on hot days and when
driving for long periods at high
speeds.
CAUTION
• Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tire pressures
at the proper levels. If a tire
frequently needs refilling, we
recommend it be checked by an
authorized HYUNDAI dealer.
• Over-inflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater
possibility of damage from road
hazards.
Check tire inflation pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You
can not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly
inflated when they are under-
inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge
firmly 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 adjustment is necessary. If
the pressure is low, add air until you
reach the recommended pressure.
Make sure to put the valve caps
back on the valve stems. 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.
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. 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 rotation
To equalize tread wear, HYUNDAI
recommends that the tires
be rotated according to the
maintenance schedule 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 pressure, 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 any 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
wheel bolt tightness (proper torque
is 79.6-94.0 lbf.ft [11.0-13.0 kgf.m]).
OHI078078
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
The outside and inside of the
unsymmetrical tire is distinguishable.
When installing an unsymmetrical
tire, be sure to install the side marked
“outside” face the outside. If the side
marked “inside” is installed on the
outside, it will have a negative effect
on vehicle performance.
WARNING
• Do not use the compact spare
tire for tire rotation.
• Do not mix bias ply and radial ply
tires under any circumstances.
This may cause unusual handling
characteristics that may cause
loss of vehicle control resulting in
an accident.

Tire speed ratings
The chart below lists many of the
different speed ratings currently
being used for passenger vehicle
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
operating speed.
Speed Rating Symbol Maximum Speed
S 112 mph (180 km/h)
T 118 mph (190 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (300 km/h)
3. Checking tire life (TIN : Tire
Identification Number)
Any tires that are over six 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 numbers
on a tire consisting of numbers and
English letters. The manufacturing
date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT shows a
plant code number, tire size and
tread pattern and the last four
numbers indicate week and year
manufactured.
For example:
DOT XXXX XXXX 1521 represents that
the tire was produced in the 15th
week of 2021.
4. Tire ply composition and material
The number of layers or plies of
rubber-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
construction; the letter “D“ means
diagonal or bias ply construction;
and the letter “B” means belted-bias
ply construction.
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
permissible 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.

WARNING
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
under-inflation, over-inflation, or
excessive loading, either separately
or in combination, can cause heat
build-up and possible sudden
tire failure. This may cause loss
of vehicle control resulting in an
accident.
Low aspect ratio tires
(if equipped)
The aspect ratio is lower than 50 on
low aspect ratio tires.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than
a standard tire. Also low aspect
ratio tires tend to be wider and
consequently have a greater contact
patch with the road surface. In some
instances they may generate more
road noise compared with standard
tires.
CAUTION
The side wall of a low aspect ratio
tire is shorter than the normal one.
Thus, the low-aspect wheel and
tire are easily damaged. Follow the
below instructions.
• When driving on a rough road or
driving off a road, be careful not
to damage the tires and wheels.
After driving, inspect the tires
and wheels.
• When passing over a pothole,
speed bump, manhole, or curb
stone, drive the vehicle slowly so
as not to damage the tires and
wheels.
• When there is an impact on a tire,
inspect the tire condition. Or,
you can contact an authorized
HYUNDAI dealer.
• Inspect the tire condition and
pressure every 8,000 miles
(13,000 km) to prevent tire
damage.
• It is difficult to recognize a tire
damage only with your eyes.
When there is a slight hint of a
tire damage, check and replace
the tire to prevent the damage
caused by air leakage.
• When a tire is damaged while
driving on a rough road, off a
road, or over obstacles, such as a
pothole, manhole, or curb stone,
your warranty does not cover the
damage.
• The tire information is specified
on the tire side wall.
