I030D01JM-AATTIRE TERMINOLOGY AND DEFINI-
TIONS
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 accesso-
ries. Some examples of optional ac-
cessories 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 op-
tional equipment including the maxi-
mum 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 compliance with the U.S. Depart-
ment of Transportation motor vehicle
safety standards. The DOT code in-
cludes the Tire Identification Number
(TIN), an alphanumeric designator which
can also identify the tire manufacturer,
production plant, brand and date of
production.
GVWR: Gross Vehicle Weight Rating
GAWR FRT: Gross Axle Weight Rating
for the front Axle.
GAWR RR: Gross Axle Weight Rating
for the rear axle. 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
(UTQG):
Tire manufacturers are required to
grade tires based on three perfor-
mance factors: treadwear, traction
and temperature resistance. For more
information, see Uniform Tire Qual-
ity Grading on page 8-12.

Intended Outboard Sidewall: The side
of an asymmetrical tire, that must al-
ways face outward when mounted on a
vehicle.
Kilopascal (kPa): The metric unit for
air pressure.
Load Index: An assigned number rang-
ing from 1 to 279 that corresponds to
the load carrying capacity of a tire.
Maximum Inflation Pressure: The
maximum air pressure to which a cold
tire may be inflated. The maximum air
pressure is molded onto the sidewall.
Maximum Load Rating: The load rat-
ing for a tire at the maximum permis-
sible inflation pressure for that tire.
Maximum Loaded Vehicle Weight:
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight: The num-
ber of occupants a vehicle is designed
to seat multiplied by 150 pounds (68
kg).Occupant Distribution: Designated
seating positions.
Outward Facing Sidewall: The side of
a asymmetrical tire that has a particular
side that faces outward when mounted
on a vehicle. The side of the tire that
contains a whitewall, bears white letter-
ing or bears manufacturer, brand and or
model name molding that is higher or
deeper than the same moldings on the
other sidewall of the tire.
Passenger (P-Metric) Tire: A tire used
on passenger cars and some light duty
trucks and multipurpose vehicles.
Recommended Inflation Pressure:
Vehicle manufacturer's recommended
tire inflation pressure and shown on the
tire placard.
Radial Ply tire: A pneumatic tire in
which the ply cords that extend to the
beads are laid at 90 degrees to the
centerline of the tread.
Rim: A metal support for a tire and upon
which the tire beads are seated.Sidewall: The portion of a tire between
the tread and the bead.
Speed Rating: An alphanumeric code
assigned to a tire indicating the maxi-
mum speed at which a tire can operate.
Traction: The friction between the tire
and the road surface. The amount of
grip provided.
Tread: The portion of a tire that comes
into contact with the road.
Treadwear Indicators: Narrow bands,
sometimes called "wear bars," that show
across the tread of a tire when only 2/32
inch of tread remains.
UTQGS: Uniform Tire Quality Grading
Standards, a tire information system
that provides consumers with ratings
for a tire's traction, temperature and
treadwear. Ratings are determined by
tire manufacturers using government
testing procedures. The ratings are
molded into the sidewall of the tire.

WARNING:
o Driving on worn-out tires is dan-
gerous! Worn-out tires can cause
loss of braking effectiveness,
steering control and traction. When
replacing tires, never mix radial
and bias ply tires on the same car.
If you replace radial tires with bias-
ply tires, they must be installed in
sets of four.
o Wheels that do not meet Hyundai's
dimensional specifications may
fit poorly and result in damage to
the vehicle, including broken
wheel studs.

WHEN TO REPLACE TIRES
The original tires on your car have tread
wear indicators . The location of tread
wear indicators is shown by the "TWI"
or " " marks, etc., The tread wear
indicators appear when the tread depth
is 0.06 in. (1.6 mm). The tire should be
replaced when these appear as a solid
bar across two or more grooves of the
tread. Always replace your tires with
those of the recommended size. If you
change wheels, the new wheel's rim
width and offset must meet Hyundai
specification.
TWI indicator 0.06 in. (1.6 mm)
I080A01A-AATTIRE 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.
