WARNING
Tire failure may cause loss of vehicle
control resulting in an accident. To
reduce risk of SERIOUS INJURY or
DEATH, take the following precautions:
• Inspect your tires monthly for proper
inflation as well as wear and damage.
• The recommended cold tire pressure
for your vehicle can be found in this
manual and on the tire label located
on the driver’s side center pillar.
Always use a tire pressure gauge to
measure tire pressure. Tires with
too much or too little pressure wear
unevenly causing poor handling.
• Check the pressure of the spare
every time you check the pressure of
the other tires on your vehicle.
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of braking
effectiveness, steering control, or
traction.
• ALWAYS replace tires with the same
type, size, brand, construction and
tread pattern as each tire that was
originally supplied with this vehicle.
Using tires and wheels other than
the recommended sizes could cause
unusual handling characteristics,
poor vehicle control, or negatively
affect your vehicle’s Anti-Lock Brake
System (ABS) resulting in a serious
accident.
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.
OCN7010009L
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side center pillar.
Recommended Cold Tire
Inflation 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 has been driven for less than one mile
(1.6 km).
Warm tires normally exceed
recommended 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 under-inflated. For
recommended inflation pressure, refer to
“Tire and Wheels” in chapter 2.

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, have it
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 label located on the driver’s
side center pillar or in this manual. 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.
A cold tire means the vehicle has been
sitting for 3 hours and driven for less
than 1 mile (1.6 km) in that 3 hour period.
Allow the tire to cool before measuring
the inflation pressure. Always be sure
the tire is cold before inflating to the
recommended pressure.

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 the tread
depth is at least 2/32 inch (1.6 mm). 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 Sidewall Labeling
This information identifies and describes
the fundamental characteristics 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 name
Manufacturer or brand name is shown.
2. Tire size designation
A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replacement
tires for your car. The following explains
what the letters and numbers in the tire
size designation mean.
Example tire size designation:
(These numbers are provided as an
example only; your tire size designator
could vary depending on your vehicle.)
205/55R16 91H
205 -Tire width in millimeters.
55 - Aspect ratio. The tire’s section
height as a percentage of its width.
R - Tire construction code (Radial).
16 - Rim diameter in inches.
91 - Load Index, a numerical code
associated with the maximum load
the tire can carry.
H - Speed Rating Symbol. See the

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.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width.
For example:
TREAD WEAR 200
TRACTION AA
TEMPERATURE ATread wear
The tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one-and-a-half times (1½) as well
on the government 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
sidewalls 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 as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.

09
9-37
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 conditions 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. Grade C 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 laboratory test
wheel than the minimum required by
law.
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.

All Season Tires
HYUNDAI specifies all season tires
on some models to provide good
performance for use all year round,
including snowy and icy road conditions.
All season tires are identified by ALL
SEASON and/or M+S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than all season tires and
may be more appropriate in some areas.
Summer Tires
HYUNDAI specifies summer tires on
some models to provide superior
performance on dry roads. Summer tire
performance is substantially reduced in
snow and ice. Summer tires do not have
the tire traction rating M+S (Mud and
Snow) on the tire side wall. If you plan
to operate your vehicle in snowy or icy
conditions, HYUNDAI recommends the
use of snow tires or all season tires on all
four wheels.
Snow Tires
If you equip your car with snow tires,
they should be the same size and have
the same load capacity as the original
tires. Snow tires should be installed on
all four wheels; otherwise, poor handling
may result. Snow tires should carry 4
psi (28 kPa) more air pressure than the
pressure recommended for the standard
tires on the tire label on the driver’s
side of the center pillar, or up to the
maximum pressure shown on the tire
sidewall, whichever is less. Do not drive
faster than 75 mph (120 km/h) when your
vehicle is equipped with snow tires.
Radial-Ply Tires
Radial-ply tires provide improved tread
life, road hazard resistance and smoother
high speed ride. The radial-ply tires used
on this vehicle are of belted construction,
and are selected to complement the
ride and handling characteristics of your
vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or bias
belted tires of the same size, and use the
same recommended inflation pressure.
Mixing of radial-ply tires with bias-ply or
bias belted tires is not recommended.
Any combinations of radial-ply and bias-
ply or bias belted tires when used on the
same vehicle will seriously deteriorate
vehicle handling. The best rule to follow
is: Identical pairs of radial-ply tires
should always be used as a set for the
front tires and a set for the rear tires.
Longer wearing tires can be more
susceptible to irregular tread wear. It is
very important to follow the tire rotation
interval in this chapter to achieve the
tread life potential of these tires. Cuts
and punctures in radial-ply tires are
repairable only in the tread area, because
of sidewall flexing. Consult your tire
dealer for radial-ply tire repairs.
WARNING
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.
