TYRES AND WHEELS
Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle. Recommended cold tyre inflation pressures All tyre pressures (including the
spare) should be checked when the
tyres are cold. “Cold Tyres” means
the vehicle has not been driven for at
least three hours or driven less than1 mile (1.6 km).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tyre
wear.
For recommended inflation pressure
refer to “Tyre and wheels” in section8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tyre underin-
flation
Severe underinflation (10 psi (0.7 bar) or more) can lead to
severe heat build-up, causing
blowouts, tread separation andother tyre failures that can
result in the loss of vehicle con-
trol leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

WARNING - Tyre inflation
Overinflation or underinflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure. This
could result in loss of vehicle
control and potential injury.
CAUTION - Tyre pressure
Always observe the following:
 Check tyre pressure when the tyres are cold. (After vehiclehas been parked for at leastthree hours or hasn't been driven more than 1 mile (1.6km) since startup.)
 Check the pressure of your spare tyre each time youcheck the pressure of other tyres.
 Never overload your vehicle. Be careful not to overload avehicle luggage rack if yourvehicle is equipped with one.
 Worn, old tyres can cause accidents. If your tread isbadly worn, or if your tyreshave been damaged, replacethem.
CAUTION
 Underinflation also results in excessive wear, poor handlingand reduced fuel economy.Wheel deformation also ispossible. Keep your tyre pres- sures at the proper levels. If atyre frequently needs refilling,have it checked by a HYUNDAI authorised repairer.
 Overinflation produces a harsh ride, excessive wear atthe centre of the tyre tread,and a greater possibility of damage from road hazards.
CAUTION
 Warm tyres normally exceed recommended cold tyre pres-sures by 4 to 6 psi (0.28 to 0.41 bar). Do not release air fromwarm tyres to adjust the pres-sure or the tyres will be under- inflated.
 Be sure to reinstall the tyre 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 tyre inflation pressure
Check your tyres once a month or
more.
Also, check the tyre pressure of the
spare tyre.
How to check
Use a good quality gauge to check
tyre pressure. You can not tell if your
tyres are properly inflated simply by
looking at them. Radial tyres may
look properly inflated even when
they're underinflated.
Check the tyre's inflation pressure
when the tyres are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven nomore than 1 mile (1.6 km).Remove the valve cap from the tyre
valve stem. Press the tyre gauge
firmly onto the valve to get a pres-
sure measurement. If the cold tyreinflation pressure matches the rec-ommended pressure on the tyre and
loading information label, no further
adjustment is necessary. If the pres-
sure is low, add air until you reachthe recommended amount.
If you overfill the tyre, release air by pushing on the metal stem in the
centre of the tyre valve. Recheck the
tyre pressure with the tyre gauge. 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 tyres frequently for proper inflation as well as
wear and damage. Always use
a tyre pressure gauge.
 Tyres with too much or too lit- tle pressure wear unevenly
causing poor handling, loss of
vehicle control, and suddentyre failure leading to acci-
dents, injuries, and even death.The recommended cold tyre
pressure for your vehicle can
be found in this manual and onthe tyre label located on the
driver's side centre pillar.
 Worn tyres can cause acci- dents. Replace tyres that are
worn, show uneven wear, or
are damaged.
 Remember to check the pres- sure of your spare tyre.
HYUNDAI recommends that
you check the spare every
time you check the pressure
of the other tyres on your
vehicle.

Tyre rotation
To equalize tread wear, it is recom- mended that the tyres be rotated
every 7,500 miles (12,000 km) or
sooner if irregular wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for
uneven wear and damage. Abnormal
wear is usually caused by incorrect
tyre pressure, improper wheel align-
ment, out-of-balance wheels, severe
braking or severe cornering. Look for
bumps or bulges in the tread or side
of tyre. Replace the tyre if you find
either of these conditions. Replace
the tyre if fabric or cord is visible.
After rotation, be sure to bring thefront and rear tyre pressures to spec-
ification and check lug nut tightness.
Refer to “Tyre and wheels” in section 8.Disc brake pads should be inspected
for wear whenever tyres are rotated.
✽✽ NOTICE
Rotate radial tyres that have an
asymmetric tread pattern only from
front to rear and not from right toleft.
WARNING
 Do not use the compact spare tyre for tyre rotation.
 Do not mix bias ply and radial ply tyres 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 tyre balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tyre
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tyre
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.Tyre replacement
If the tyre is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This showsthere is less than 1.6 mm (1/16 in.) of
tread left on the tyre. Replace the
tyre when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tyre.
CAUTION
Improper wheel weights can
damage your vehicle's alu-minum wheels. Use only approved wheel weights.
WARNING - Replacing
tyres
 Driving on worn-out tyres is very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-tion.
 Your vehicle is equipped with tyres designed to provide for
safe ride and handling capa-
bility. Do not use a size andtype of tyre and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tyres, be sure to equip all
four tyres with the tyre and
wheel of the same size, type,
tread, brand and load-carrying
capacity.

Compact spare tyre replacement
(if equipped)
A compact spare tyre has a shorter
tread life than a regular size tyre.
Replace it when you can see the
tread wear indicator bars on the tyre.The replacement compact spare tyre
should be the same size and design
tyre as the one provided with your
new vehicle and should be mountedon the same compact spare tyre
wheel. The compact spare tyre is notdesigned to be mounted on a regular
size wheel, and the compact spare
tyre wheel is not designed for mount-
ing a regular size tyre. 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.
(Continued)
 The use of any other tyre size
or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tyre clearance, snow tyre
clearance, and speedometer
reliability.
 It is best to replace all four tyres at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tyres as a pair.Replacing just one tyre can
seriously affect your vehicle’shandling.
 The ABS works by comparing the speed of the wheels. Tyre
size can affect wheel speed.
When replacing tyres, all 4
tyres must use the same size
originally supplied with the
vehicle. Using tyres of a dif-
ferent size can cause the ABS
(Anti-lock Brake System) and
ESP (Electronic Stability
Program) (if equipped) to
work irregularly.
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-tyre clearance,
snow chain clearance,speedometer and odometer cal-
ibration, headlight aim and
bumper height.

Tyre traction
Tyre traction can be reduced if you
drive on worn tyres, tyres that are
improperly inflated or on slippery
road surfaces. Tyres should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tyre maintenance In addition to proper inflation, correct wheel alignment helps to decrease
tyre wear. If you find a tyre is worn
unevenly, have your dealer check thewheel alignment.
When you have new tyres installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tyre life. Additionally, a tyre should
always be rebalanced if it is removedfrom the wheel.Tyre sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tyre and also provides
the tyre identification number (TIN)
for safety standard certification. TheTIN can be used to identify the tyre incase of a recall.
1. Manufacturer or brand name
Manufacturer or Brand name is
shown.
2. Tyre size designation
A tyre’s sidewall is marked with a tyre
size designation. You will need this
information when selecting replace-
ment tyres for your car. The following
explains what the letters and num-
bers in the tyre size designationmean.
Example tyre size designation:

The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger cars. The speed
rating is part of the tyre size desig-
nation on the sidewall of the tyre.This symbol corresponds to that
tyre's designed maximum safe oper-ating speed.3. Checking tyre life
(TIN : Tyre Identification Number)
Any tyres that are over 6 years,
based on the manufacturing date,
tyre strength and performance,
decline with age naturally (even
unused spare tyres). Therefore, thetyres (including the spare tyre)
should be replaced by new ones. You
can find the manufacturing date on
the tyre sidewall (possibly on the
inside of the wheel), displaying the
DOT Code. The DOT Code is a
series of numbers on a tyre consist-
ing of numbers and English letters.
The manufacturing date is designat-
ed 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, tyre size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1609 represents
that the tyre was produced in the
16th week of 2009.
