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.

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.

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 size designation
Wheels are also marked with impor-
tant information that you need if you
ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-tion mean.
Example wheel size designation: 5.0JX14
5.0 - Rim width in inches. J - Rim contour designation.
14 - Rim diameter in inches. Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger car tire. 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 oper-ating speed.3. Checking tire life (TIN : Tire
Identification Number)
Any tires that are over 6 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 num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1613 represents
that the tire was produced in the 16th
week of 2013.
