Important - use of compact spare tire
Your vehicle is equipped with a com-
pact spare tire. This compact spare
tire takes up less space than a regu-
lar-size tire. This tire is smaller than a
conventional tire and is designed for
temporary use only.
The compact spare should be inflat-
ed to 60 psi (420 kPa).
✽ ✽NOTICE
Check the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
When using a compact spare tire,
observe the following precautions:
Under no circumstances should
you exceed 50 mph (80 km/h); a
higher speed could damage the
tire.
Ensure that you drive slowly enough for the road conditions to
avoid all hazards. Any road hazard,
such as a pothole or debris, could
seriously damage the compact
spare.
Any continuous road use of this tire could result in tire failure, loss of
vehicle control, and possible per-
sonal injury.
Do not exceed the vehicle’s maxi- mum load rating or the load-carry-
ing capacity shown on the sidewall
of the compact spare tire.
Avoid driving over obstacles. The compact spare tire diameter is
smaller than the diameter of a con-
ventional tire and reduces the
ground clearance approximately 1
inch (25 mm), which could result in
damage to the vehicle.
WARNING
The temporary spare tire is for
emergency use only. Do not
operate your vehicle on this
temporary spare at speeds over
50 mph (80 kmh). The original
tire should be repaired or
replaced as soon as is possible
to avoid failure of the spare
possibly leading to personal
injury or death.
CAUTION
You should drive carefully when the compact spare is inuse. The compact spareshould be replaced by theproper conventional tire andrim at the first opportunity.
The operation of this vehicle is not recommended withmore than one compact sparetire in use at the same time.

TIRES AND WHEELS
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.
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 driven less than
one mile (1.6 km).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear. All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
WARNING - Tire underin-
flation
Severe underinflation (10 psi
(70 kPa) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

OHD086003
WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and
sudden tire failure leading to
accidents, injuries, and even
death. Always check tires are
properly inflated before driv-
ing.
Driving on tires with no or insufficient tread is danger-
ous. Worn-out tires can result
in loss of vehicle control, col-
lisions, and injury and even
death. Worn-out tires should
be replaced as soon as possi-
ble and should never be used
for driving. Always check tire
tread before driving your car.

WARNING - Tire inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.
CAUTION - Tire pressure
Always observe the following: Check tire pressure when the tires are cold. (After vehiclehas been parked for at leastthree hours or hasn't beendriven more than one mile (1.6km) since startup.)
Check the pressure of your spare tire each time you checkthe pressure of other tires.
Never overload your vehicle. Be careful not to overload avehicle luggage rack if yourvehicle is equipped with one.
Worn, old tires can cause acci- dents. If your tread is badlyworn, or if your tires havebeen damaged, replace them.
CAUTION
Underinflation also results in excessive wear, poor handlingand reduced fuel economy.Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If atire frequently needs refilling,have it checked by an author-ized Hyundai dealer.
Overinflation produces a harsh ride, excessive wear atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
CAUTION
Warm tires normally exceed recommended cold tire pres-sures by 4 to 6 psi (28 to 41kPa). Do not release air fromwarm tires to adjust the pres-sure or the tires will be under-inflated.
Be sure to reinstall the tire inflation valve caps. Withoutthe valve cap, dirt or moisturecould get into the valve coreand cause air leakage. If avalve cap is missing, install anew one as soon as possible.

Checking tire inflation pressure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use 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 mile (1.6 km).
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.
When significant temperature
changes occur, the tire pressures will
need to be adjusted. The pressure
will drop approximately 1 psi for each
12 degree temperature drop. If set-
ting tire pressure in a warm garage
during the winter, it is possible the
TPMS telltale will illuminate after the
car has been parked outside. It is
important for the safety of the occu-
pants that the tire preform the TPMS
system are set correctly.
Refer to section 6 for additional infor-
mation on the Tire Pressure
Monitoring System (TPMS).
WARNING
Inspect your tires frequently
for proper inflation as well as
wear and damage. Always use
a tire pressure gauge.
Tires with too much or too lit- tle pressure wear unevenly
causing poor handling, loss of
vehicle control, and sudden
tire failure leading to acci-
dents, injuries, and even
death. 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 of the cen-
ter pillar.
Worn tires can cause acci- dents. Replace tires that are
worn, show uneven wear, or
are damaged.
Remember to check the pres- sure of your spare tire.
Hyundai recommends that
you check the spare every
time you check the pressure
of the other tires on your vehi-
cle.

4. Tire ply composition and material
The number of layers or plies of rub-
ber-coated fabric are 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 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 maxi-
mum section width.
For example:
TREAD wear 200
TRACTION AA
TEMPERATUE A
Tread wear
The 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
because of variations in driving
habits, service practices and differ-
ences in road characteristics and cli-
mate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
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 tires ability to
stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING - Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires tread, It is recommended
that tires generally be replaced
after 6 years of normal service.
Heat caused by not climates or
frequent high loading
Conditions can accelerate the
aging process. Failure to follow
this Warning can result in sud-
den tire failure, which could
lead to a loss of control and an
accident involving serious
injury or death.

741
Maintenance
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. The grade C cor-
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 labora-
tory test wheel than minimum
required by law.Tire terminology and definitions
Air Pressure

The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
build-up and possible sudden
tire failure. This can cause loss
of vehicle control and serious
injury or death.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.
