2012 Hyundai Genesis spare wheel

Maintenance
CAUTION
• Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
have it checked by an author-
ized HYUNDAI dealer.
• Overinflation produces a
harsh ride, excessive wear at
the center of the tire tread, and
a greater possibility of dam-
age from road hazards.

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.
G200200AEN
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
1.6 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 section
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tire underin-
flation
Severe underinflation 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.

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 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.G200400ABH
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.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 tire
failure leading to accidents,
injuries, and even death. The
recommended cold tire pres-
sure for your vehicle can be
found in this manual and on
the 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.

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.
G200500AUN
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 need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.

WARNING
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
could result in death, severe
injury, or property damage.
CAUTION
Improper wheel weights can
damage your vehicle's alu-
minum wheels. Use only
approved wheel weights.

Tire replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less 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.
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, 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)(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
ESP (Electronic Stability
Program) to work irregularly.

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.
G201003AEN
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 1612 represents
that the tire was produced in the 16th
week of 2012.
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)

WARNING - 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 or
frequent 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 or
death.
