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.
All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.

Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tires monthly for
proper inflation as well as
wear and damage.
The recommended cold tire pressure for your vehicle can
be found in this manual and
on the tire label located on the
driver’s side center pillar.
Always use a tire pressure
gauge to measure tire pres-
sure. Tires with too much or
too little pressure wear
unevenly causing poor han-
dling.
Check the pressure of the spare every time you check
the pressure of the other tires
on your vehicle.
Replace tires that are worn, show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering) control, or
traction.
ALWAYS replace tires with the same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle's Anti-Lock Brake System
(ABS) resulting in a serious
accident.

Maintenance
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
one mile (1.6 km).
Warm tires normally exceed recom-
mended cold tire pressures by 4 to 6
psi (28 to 41 kPa). Do not release air
from warm tires to adjust the pres-
sure or the tires will be under-inflat-
ed. For recommended inflation pres-
sure, refer to "Tire and Wheels" in
chapter 8. Under-inflation results in exces-
sive wear, poor handling and
reduced fuel economy. Wheel
deformation is also possible.
Keep your tire pressures at the
proper levels. If a tire frequently
needs refilling, have it checked by
an authorized retailer of Genesis
Branded products.
Over-inflation produces a harsh ride, excessive wear at the cen-
ter of the tire tread, and a greater
possibility of damage from road
hazards.
NOTICE
Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
resulting in an accident. This
risk is much higher on hot days
and when driving for long peri-
ods at high speeds.

Tire Terminology and
Definitions
Air Pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory Weight
This means the combined weight of
optional accessories. Some exam-
ples of optional accessories are
automatic transmission, power
seats, and air conditioning.
Aspect Ratio
The relationship of a tire's height to
its width.
Belt
A rubber coated layer of cords that is
located between the plies and the
tread. Cords may be made from steel
or other reinforcing materials.
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias Ply Tire
A pneumatic tire in which the plies
are laid at alternate angles less than
90 degrees to the centerline of the
tread.
Cold Tire Pressure
The amount of air pressure in a tire,
measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire
has built up heat from driving.
Curb Weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT Markings
A code molded into the sidewall of a
tire signifying that the tire is in com-
pliance with the U.S. Department of
Transportation motor vehicle safety
standards. The DOT code includes
the Tire Identification Number (TIN),
an alphanumeric designator which
can also identify the tire manufactur-
er, production plant, brand and date
of production.
