Maintenance
Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is pos-
sible. Keep your tire pressures
at the proper levels. If a tire fre-
quently needs refilling, we rec-
ommend that the system be
checked by an authorized
HYUNDAI dealer.
Overinflation produces a harsh
ride, excessive wear at the cen-
ter of the tire tread, and a greater
possibility of damage from road
hazards. Warm tires normally exceed rec-
ommended cold tire pressures
by 28 to 41 kPa (4 to 6 psi). Do
not release air from warm tires
to adjust the pressure or the
tires will be underinflated.
Be sure to reinstall the tire infla-
tion valve caps. 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.- Tire pressure
Always observe the following:
Check tire pressure when the
tires are cold. (After vehicle has
been parked for at least three
hours or hasn't been driven
more than 1.6 km (one mile)
since startup.)
Check the pressure of your
spare tire each time you check
the pressure of other tires.
Never overload your vehicle. Be
careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
Worn, old tires can cause acci-
dents. If your tread is badly
worn, or if your tires have been
damaged, replace them.
NOTICENOTICENOTICE
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.

Maintenance
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 chap-
ter 8.Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
Rotate radial tires that have an asym-
metric tread pattern only from front
to rear and not from right to left.

Without a spare tire With a full-size spare tire (if equipped)
Directional tires (if equipped)
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.

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. 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, and
traction.
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.
(Continued)
WARNING (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.
When replacing tires (or
wheels), it is recommended to
replace the two front or two
rear tires (or wheels) as a pair.
Replacing just one tire can
seriously affect your vehicle’s
handling.
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) to work irregularly. (if
equipped)
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.

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:
6.0JX16
6.0 - Rim width in inches.
J - Rim contour designation.
16 - Rim diameter in inches.
Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger car tires. 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 1518 represents
that the tire was produced in the 15th
week of 2018.
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
Z Above 240 km/h (149 mph)
W*270 km/h (168 mph)
