4. Tire ply composition andmaterial
The number of layers or plies of rub-
ber-coated fabric 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:
TREAD wear 200
TRACTION AA
TEMPERATURE A
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
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
sidewalls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.

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.
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.

7-50
Maintenance
Vehicle Capacity Weight
The number of designated seating
positions multiplied by 150 lbs. (68
kg) plus the rated cargo and luggage
load.
Vehicle Maximum Load on theTire
Load on an individual tire due to curb
and accessory weight plus maximum
occupant and cargo weight.
Vehicle Normal Load on the Tire
Load on an individual tire that is
determined by distributing to each
axle its share of the curb weight,
accessory weight, and normal occu-
pant weight and dividing by 2.
Vehicle Placard
A label permanently attached to a
vehicle showing the original equip-
ment tire size and recommended
inflation pressure.
All Season Tires
Genesis Branded Vehicle specifies
all season tires on some models to
provide good performance for use all
year round, including snowy and icy
road conditions. All season tires are
identified by ALL SEASON and/or
M+S (Mud and Snow) on the tire
sidewall. Snow tires have better
snow traction than all season tires
and may be more appropriate in
some areas.
Summer Tires
Genesis Branded Vehicle specifies
summer tires on some models to
provide superior performance on dry
roads. Summer tire performance is
substantially reduced in snow and
ice. Summer tires do not have the tire
traction rating M+S (Mud and Snow)
on the tire side wall. If you plan to
operate your vehicle in snowy or icy
conditions, Genesis Branded Vehicle
recommends the use of snow tires or
all season tires on all four wheels.
Snow Tires
If you equip your car with snow tires,
they should be the same size and
have the same load capacity as the
original tires. Snow tires should be
installed on all four wheels; other-
wise, poor handling may result. Snow
tires should carry 4 psi (28 kPa)
more air pressure than the pressure
recommended for the standard tires
on the tire label on the driver’s side of
the center pillar, or up to the maxi-
mum pressure shown on the tire
sidewall, whichever is less. Do not
drive faster than 75 mph (120 km/h)
when your vehicle is equipped with
snow tires.

Radial-Ply Tires
Radial-ply tires provide improved
tread life, road hazard resistance and
smoother high speed ride. The radi-
al-ply tires used on this vehicle are of
belted construction, and are selected
to complement the ride and handling
characteristics of your vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or bias
belted tires of the same size, and use
the same recommended inflation
pressure. Mixing of radial-ply tires
with bias-ply or bias belted tires is
not recommended. Any combina-
tions of radial-ply and bias-ply or bias
belted tires when used on the same
vehicle will seriously deteriorate
vehicle handling. The best rule to fol-
low is: Identical pairs of radial-ply
tires should always be used as a set
for the front tires and a set for the
rear tires.
Longer wearing tires can be more
susceptible to irregular tread wear. It
is very important to follow the tire
rotation interval in this chapter to
achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.
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 oroff road, drive cautiously because
tires and wheels may be dam-
aged. 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 retail-
er of Genesis Branded products.
- Inspect the tire condition and pres- sure every 1,800 miles (3,000km).
NOTICE
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
may cause loss of vehicle con-
trol resulting in an accident.
