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 than1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire and wheels” in chapter 8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tire underin-
flation
Severe underinflation (70 kPa (10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation andother 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.

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 been driven more than 1.6 km (onemile) 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 have been 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 a tire frequently needs refilling,we recommend that the sys-tem be 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 28 to 41 kPa (4 to 6 psi). 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 core and cause air leakage. If avalve cap is missing, install anew one as soon as possible.

743
Maintenance
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 nomore 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 inflationpressure matches the recommendedpressure 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.
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 little pressure wear unevenly caus-
ing poor handling, loss of vehi-
cle control, and sudden tirefailure leading to accidents,
injuries, and even death. Therecommended cold tire pres-
sure for your vehicle can be
found in this manual and onthe tire label located on the dri-
ver's side center 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.

Tire rotation
To equalize tread wear, it is recom- mended that the tires be rotated
every 12,000 km (7,500 miles) 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 pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either 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
lug nut tightness.
Refer to “Tire and wheels” in chapter 8.
Disc brake pads should be inspected
for wear whenever tires are rotated.
✽✽ NOTICE
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to
left.
WARNING
Do not use the compact spare tire for tire rotation.
Do not mix bias ply and radial ply tires under any circum-
stances. This may cause
unusual handling characteris-tics that could result in death,
severe injury, or property
damage.

Maintenance
Wheel alignment and tire balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may needto be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.Tire replacement
If the tire is worn evenly, a tread wear indicator will appear as a solid band
across the tread. This shows there isless than 1.6 mm (1/16 inch) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
CAUTION
Improper wheel weights can
damage your vehicle's alu-minum wheels. Use only approved wheel weights.
OEN076053
Tread wear indicatorWARNING - Replacing
tires
To reduce the chance or serious
or fatal injuries from an acci-
dent caused by tire failure or
loss of vehicle control:
Replace tires that are worn, show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering control, andtraction.
Do not drive your vehicle with too little or too much pressure
in your tires. This can lead to
uneven wear and tire failure.
When replacing tires, never mix radial and bias-ply tires
on the same car. You must
replace all tires (including the
spare) if moving from radial to
bias-ply tires.

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 widthand 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. Slow down whenever there
is rain, snow or ice on the road, toreduce the possibility of losing con-trol.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,speedometer and odometer cal-
ibration, headlight aim and
bumper height.
(Continued)
Using tires and wheel other than the recommended sizes
could cause unusual handling
characteristics and poor vehi-
cle control, resulting in a seri-ous accident.
Wheels that do not meet HYUNDAI’s specifications
may fit poorly and result in
damage to the vehicle or
unusual handling and poor
vehicle control.
The ABS works by comparing the speed of the wheels. Tire
size can affect wheel speed.
When replacing tires, all 4
tires must use the same size
originally supplied with the
vehicle. Using tires of a differ-
ent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) (if equipped) to work
irregularly.

747
Maintenance
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 thewheel 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 removedfrom the wheel.Tire sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. TheTIN can be used to identify the tire incase of a recall.
