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.

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.

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 the
wheel 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 removed
from the wheel.

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. The
TIN can be used to identify the tire in
case of a recall.

1. Manufacturer or brand name

Manufacturer or Brand name is
shown.

2. Tire size designation  

A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replace-
ment tires for your car. The following
explains what the letters and num-
bers in the tire size designation
mean.
Example tire size designation:
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.)

A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling char-
acteristics, ground clearance,
body-to-tire clearance, snow
chain clearance, speedometer
and odometer calibration, head-
lamp 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:
8.0J X 18

8.0 - Rim width in inches.
J - Rim contour designation.
18 - 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,
tire strength and performance,
decline with age naturally (even
unused spare tires). Therefore, the
tires (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
numbers on a tire consisting of num-
bers and English letters. The manu-
facturing 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 2216 represents
that the tire was produced in the 22th
week of 2016.

4. Tire ply composition and

material

The number of layers or plies of rub-
ber-coated fabric are in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.

5. Maximum permissible infla-

tion pressure

This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.

6. Maximum load rating

This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.

7. Uniform tire quality grading 

Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 200 
TRACTION AA 
TEMPERATURE A

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.

WARNING

7-48

Maintenance

Tread wear

The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
because of variations in driving
habits, service practices and differ-
ences in road characteristics and cli-
mate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
may vary with respect to grade.

Traction - AA, A, B & C 

The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tires ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.

Temperature -A, B & C 

The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grades B and A
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by the
law.

The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.

WARNING

Tire temperature
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation,

or excessive

loading, either separately or in
combination, can cause heat
build-up and possible sudden
tire failure. This can cause loss
of vehicle control and serious
injury or death.

WARNING

Low Aspect Ratio Tires

Low aspect ratio tires, the aspect
ratio is lower than 50, are provided
for sporty looks.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than a
standard tire. Also low aspect ratio
tires tend to be wider and conse-
quently have a greater contact patch
with the road surface. In some
instances they may generate more
road noise compared with standard
tires.

Because the sidewall of a low
aspect ratio tire is shorter than a
standard tire, the rim of the wheel
and the tire itself is more easily
susceptible to damage. Use cau-
tion when driving and follow the
guidelines below to help minimize
damage to the wheel and tire:
- When driving on a rough road or

off road,

drive cautiously

because tires and wheels may
be damaged. And after driving,
inspect tires and wheels.

- When passing over a pothole,

speed bump, manhole, or curb
stone, drive slowly so that the
tires and wheels are not dam-
aged.

- If the tire is subjected to a severe

impact, have the tire and wheel
inspected by an authorized
retailer of Genesis Branded
products.

- Inspect the tire condition and

pressure every 1,800 miles
(3,000km).

• It is not easy to recognize tire

damage with your own eyes. But
if there is the slightest hint of
tire damage,

have the tire

checked or replaced because
the tire damage may cause air
leakage from the tire.

• If the tire is damaged by driving

on a rough road, off road, pot-
hole, manhole, or curb stone, it
will not be covered by the war-
ranty.

Maintenance

A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 4 fuse panels, one
located in the driver’s side panel bol-
ster, another in the engine compart-
ment, and two others in the trunk
compartment.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted.
If the electrical system does not work,
first check the driver’s side fuse panel.

Before replacing a blown fuse, dis-
connect the negative battery cable.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized retailer
of Genesis Branded products.
Four kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, multi fuse and fusible link
for higher amperage ratings.

Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.
