TYRES AND WHEELS
Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre infla-
tion pressures and stay within the load
limits and weight distribution recom-
mended for your vehicle. Recommended cold tyre inflation pressures All tyre pressures (including the spare)
should be checked every day when the
tyres are cold. “Cold Tyres” 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 main-
tained for the best ride, top vehicle han-
dling, and minimum tyre wear. All specifications (sizes and pressures)
can be found on a label attached to the
vehicle.
WARNING - Tyre underin-
flation
Severe underinflation (70 kPa (10
psi) or more) can lead to severe
heat build-up, causing blowouts,tread separation and other tyre fail-ures 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 driv-
ing for protracted periods at highspeeds.

WARNING - Tyre inflation
Overinflation or underinflation can
reduce tyre life, adversely affect
vehicle handling, and lead to sud-
den 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 vehicle hasbeen parked for at least threehours or hasn't been driven more
than 1.6 km (one mile) since start- up.)
Check the pressure of your spare tyre each time you check thepressure of other tyres.
Never overload your vehicle. Be careful not to overload a vehicleluggage rack if your vehicle is equipped with one.
Worn, old tyres can cause acci- dents. If your tread is badly worn,or if your tyres have been dam- aged, replace them.
CAUTION
Underinflation also results in
excessive wear, poor handlingand reduced fuel economy. Wheeldeformation also is possible.
Keep your tyre pressures at theproper levels. If a tyre frequentlyneeds refilling, have it checked byan authorised Hyundai dealer.
Overinflation produces a harsh ride, excessive wear at the centreof the tyre tread, and a greaterpossibility of damage from road
hazards.
CAUTION
Warm tyres normally exceed rec- ommended cold tyre pressuresby 28 to 41 kPa (4 to 6 psi). Do notrelease air from warm tyres to
adjust the pressure or the tyres will be underinflated.
Be sure to reinstall the tyre infla- tion valve caps. Without the valvecap, 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 pos-
sible.

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
pressures. 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 no more than 1.6 km (1mile). Remove the valve cap from the tyre valve
stem. Press the tyre gauge firmly onto
the valve to get a pressure measure-
ment. If the cold tyre inflation pressurematches the recommended pressure on
the tyre and loading information label, no
further adjustment is necessary. If the
pressure 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 pres-
sure 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 moisture.
Tyre rotation
To equalise tread wear, it is recommend-
ed that the tyres be rotated every 12,000km (7,500 miles) or sooner if irregular
wear develops.
During rotation, check the tyres for cor-
rect balance.
When rotating tyres, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tyre 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 tyre.
Replace the tyre if you find either of
these conditions. Replace the tyre if fab-
ric or cord is visible. After rotation, be
sure to bring the front and rear tyre pres-
sures to specification and check lug nut
tightness.
Refer to Section 8, “Specifications”.

Maintenance
Disc brake pads should be inspected forwear whenever tyres are rotated.
✽✽NOTICE
Rotate radial tyres that have an asym-
metric tread pattern only from front to
rear and not from right to left.
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 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
tyres under any circumstances.
This may cause unusual handling
characteristics that could result in
death, severe injury, or property
damage.S2BLA790

Tyre replacement
If the tyre is worn evenly, a tread wear indicator will appear as a solid band
across the tread. This shows there is lessthan 1.6 mm (1/16 inch) of tread left on
the tyre. Replace the tyre when this hap-
pens.
Do not wait for the band to appear across
the entire tread before replacing the tyre.
WARNING - Replacing
tyres
Driving on worn-out tyres is very hazardous and will reduce brak-
ing effectiveness, steering accu-
racy, and traction.
Your vehicle is equipped with tyres designed to provide for safe
ride and handling capability. Do
not use a size and type 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
vehicle, which could lead to han-
dling failure or rollover and seri-
ous injury. When replacing the
tyres, be sure to equip all fourtyres with the tyre and wheel of
the same size, type, tread, brand
and load-carrying capacity.

Tread wear indicator(Continued)
The use of any other tyre size ortype may seriously affect ride,
handling, ground clearance, stop-
ping distance, body to tyre clear-
ance, 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’s handling.
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 sup-
plied with the vehicle. Using tyres
of a different size can cause the
ABS (Anti-lock Brake System)
and ESP (Electronic Stability
Program) (if equipped) to work
irregularly.

Compact spare tire replacement (if equipped)
A compact spare tire has a shorter tread
life than a regular size tire. Replace it
when you can see the tread wear indica-
tor bars on the tire. The replacementcompact spare tire should be the same
size and design tire as the one provided
with your new vehicle and should bemounted on the same compact spare tire
wheel. The compact spare tire is notdesigned to be mounted on a regular
size wheel, and the compact spare tire
wheel is not designed for mounting a reg-
ular size tire. 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. 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 onthe 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 the wheel align-ment.
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 removed from thewheel.
Tyre sidewall labeling
This information identifies and describes
the fundamental characteristics of the
tyre and also provides the tyre identifica-
tion number (TIN) for safety standard
certification. The TIN can be used toidentify the tyre in case of a recall.

2. Tyre size designation
A tyre’s sidewall is marked with a tyre
size designation. You will need this infor-mation when selecting replacement tyres
for your car. The following explains what
the letters and numbers in the tyre sizedesignation mean.
Example tyre size designation:
(These numbers are provided as an
example only; your tyre size designator
could vary depending on your vehicle.) P205/55R16 89H
P - Applicable vehicle type (tyres marked with the prefix “P” are intended for
use on passenger cars or light trucks;
however, not all tyres have this mark-ing).
205 - Tyre width in millimeters.
55 - Aspect ratio. The tyre’s section height as a percentage of its width.
R - Tyre construction code (Radial).
16 - Rim diameter in inches.
89 - Load Index, a numerical code asso- ciated with the maximum load the
tyre can carry.
H - Speed Rating Symbol. See the speed rating chart in this section for addi-
tional information. Wheel size designation
Wheels are also marked with important
information that you need if you ever
have to replace one. The following
explains what the letters and numbers in
the wheel size designation mean.

3. Checking tyre life (TIN : TyreIdentification 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), dis-
playing the DOT Code. The DOT Code is
a series of numbers on a tyre consisting
of numbers and English letters. The
manufacturing 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, tyre size and tread pattern
and the last four numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 1606 represents that
the tyre was produced in the 16th weekof 2006.
4. Tyre ply composition and material
The number of layers or plies of rubber-
coated fabric are in the tyre. Tyre manu-
facturers also must indicate the materials
in the tyre, which include steel, nylon,
polyester, and others. The letter "R"
means radial ply construction; the letter
"D" means diagonal or bias ply construc-
tion; and the letter "B" means belted-bias
ply construction.
5. Maximum permissible inflationpressure
This number is the greatest amount of air
pressure that should be put in the tyre.
Do not exceed the maximum permissible
inflation pressure. Refer to the Tyre and
Loading Information label for recom-
mended inflation pressure.
6. Maximum load rating
This number indicates the maximum load
in kilograms and pounds that can be car-
ried by the tyre. When replacing the tyres
on the vehicle, always use a tyre that has
the same load rating as the factory
installed tyre.
WARNING - Tyre age
Tyres degrade over time, even
when they are not being used.
Regardless of the remaining tread,it is recommended that tyres tread,
It is recommended that tyres gener-
ally be replaced after 6 years of nor-
mal service. Heat caused by not cli-mates or frequent high loadingConditions can accelerate the
aging process. Failure to follow this
Warning can result in sudden tyre
failure, which could lead to a loss
of control and an accident involving
serious injury or death.
