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 infla- tion 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 (1 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 section8.

Overinflation or underinfla-
tion can reduce tire life,
adversely affect vehicle han-
dling, and lead to sudden tire
failure. You must always main-tain recommended tire pres-sures.
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.
Tire underinflation
If the tire pressure drops
repeatedly, the wheel, valve or
tire may be damaged. Underinflation results in reducing fitness of tire and
wheel, excessive wear, poorhandling and reduced fuel
economy. (Continued)
(Continued)
And it can lead to deformation or abnormal wear of wheel,
severe heat build-up, causing
blowouts, tread separationand 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 periodsat high speeds.
If the problem is not solved (a
tire frequently needs refilling),we recommend that the sys-
tem be checked by an author-
ized HYUNDAI dealer.
Tire overinflation
Tires with excessively high
pressure can burst because
they are damaged more easily
by road debris, potholes etc.
In addition, they also produce
a harsh ride, excessive wearat the center of the tire tread,and a greater possibility of
damage from road hazards.

Maintenance
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.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 section 8.
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 suddentire failure leading to acci-
dents, injuries, and even
death. The recommended cold
tire pressure for your vehicle
can be found in this manualand on the tire label locatedon the driver's side center pil-
lar.
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.

Maintenance
Disc brake pads should be inspectedfor wear whenever tires are rotated.
Rotate radial tires that have an
asymmetric tread pattern only
from front to rear and not fromright to left.
Wheel alignment and tire bal- ance
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.NOTICE
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.
WARNING
Improper wheel weights can
damage your vehicle's alu-
minum wheels. Use only
approved wheel weights.

Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger vehicles. 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, based
on the manufacturing date, tire
strength and performance, decline
with age naturally (even unused
spare tires). Therefore, the tires(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 1615 represents
that the tire was produced in the 16th
week of 2015. Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires generally be replaced after
six (6) years of normal service.
Heat caused by hot climates orfrequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
Warning can result in sudden
tire failure, which could lead to
a loss of control and an acci-
dent involving serious injury ordeath.
