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.

Maintenance

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 101~116 lbf.ft [14~16 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.

Maintenance

Compact 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
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
mounting a regular size tire.
WARNING
The original tire should be repaired or
replaced as soon as possible to avoid
failure of the spare and loss of vehicle
control resulting in an accident. The
compact spare tire is for emergency
use only. Do not operate your vehicle
over 50 mph (80 km/h) when using the
compact spare tire.
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.
Tire traction
Tire 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. To reduce the
possibility of losing control, slow down
whenever there is rain, snow or ice on
the road.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tire
wear. If you find a tire is 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 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 lif e (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 1520 represents that
the tire was produced in the 15th week
of 2020.
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
pr essure
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.
