Compact spare tire replacement (ifequipped)
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mountedon 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 mount-
ing a regular size tire. G200700ABK 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.
✽✽
NOTICE
The front tire size is different from
the rear tire size. So when you rotate
tires, check the tire and wheel size.
(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 size origi-
nally supplied with the vehi-
cle. Using tires of a different
size can cause the ABS (Anti-
lock Brake System) and ESP
(Electronic Stability Program)
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-tire clearance,
snow chain clearance,speedometer and odometer cal-
ibration, headlight aim and
bumper height.

G200800AUN Tire traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires 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.
G200900AUN Tire maintenance In addition to proper inflation, correct wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check thewheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removedfrom the wheel. G201000ABK
Tire sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. TheTIN can be used to identify the tire incase of a recall.

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

G201003AEN3. 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 1606 represents
that the tire was produced in the 16th
week of 2006.
