Uniform Tire Quality GradingQuality grades can be found where applica-
ble on the tire sidewall between tread shoul-
der and maximum section width. For
example:Treadwear 200 Traction AA
Temperature AThe following information relates to the
system developed by the United States
National Highway Traffic Safety Administra-
tion, which grades tires by treadwear, trac-
tion and temperature performance. (This
applies only to vehicles sold in the United
States.) The grades are molded on the side-
walls of most passenger car tires. The Uni-
form Tire Quality Grading system does not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12
inches (25 to 30 cm), or to some limited-pro-
duction tires.
While the tires available on General Motors
passenger cars and light trucks may vary
with respect to these grades, they must also
conform to federal safety requirements and
additional General Motors Tire Perfor-
mance Criteria (TPC) standards.
TreadwearThe treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions on
a specified government test course. For
example, a tire graded 150 would wear one
and a half (1.5) times as well on the govern-
ment course as a tire graded 100. The rela-
tive 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 prac-
tices and differences in road characteristics
and climate.Traction – AA, A, B, CThe traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled condi-
tions on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance. War-
ning: The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature – A, B, CThe temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled
conditions 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 tempera-
ture can lead to sudden tire failure. The
grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the minimum
required by law.
Warning: The temperature grade for this tire
is established for a tire that is properly infla-
ted and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
heat buildup and possible tire failure.

226 Car care and technical informationLoading Your VehicleThis is an example of what your vehicle´s
Tire-Loading Information/Certification label
might look like. It is located on the B-pillar
and shows how much weight your vehicle
may properly carry. The label tells you the
proper size, and recommended inflation
pressures for the tires on your vehicle. It
also gives you important information about
the number of people that can be in your
vehicle and the total weight that you can
carry. This weight is called the Vehicle
Capacity Weight, and includes the weight of
all occupants, cargo and all nonfactory-
installed options.
Tire Terminology and DefinitionsAir Pressure:
The amount of air inside the
tire pressing outward on each square inch of
the tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:
This means the combi-
ned weight of optional accessories, for
example, automatic transmission, power
steering, power brakes, power windows,
power seats, radio 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 rein-
forcecing materials.
Bias Ply Tire:
A pneumatic tire in which the
ply cords that extend to the beads are laid at
alternate angles substantially less than 90
degrees to the centerline of the tread.
Cold Inflation Pressure:
The amount of air
pressure in a tire, measured in pounds per
square inch (psi) or kilopascal (kPa), before
a tire have built up heat from driving. See
“Inflation - Tire Pressure” on page 217.
Curb weight:
This means the weight of a
motor vehicle with standard and optional
equipment including the maximum capacity
of fuel, oil and coolant, 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. Department of
Transportation motor vehicle safety stan-
dards. The DOT code includes the Tire
Identification Number (TIN), an alphanume-
ric designator which can also indentify the
tire manufacturer, production plant, brand
and date of production.
GVWR:
Gross Vehicle Weight Rating see
“Loading Your Vehicle” on page 226.
GAWR FRT:
Gross Axle Weight Rating for
the front axle, see “Loading Your Vehicle”
on page 226.
GAWR RR:
Gross Axle Weight Rating for
the rear axle, see “Loading Your Vehicle” on
page 226.
Intended Outboard Sidewall:
The side of
an asymmetrical tire that must always face
outward when mounted on a vehicle.
Kilopascal (kPa):
The metric unit for air
pressure. There are 6.9 kPa to one psi.
Light Truck (LT-Metric) Tire:
A tire used
on light duty trucks and some multipurpose
passenger vehicles.
Load Index:
An assigned number ranging
from 1 to 279 that corresponds to the load
carrying capacity of a tire.
This label can only be found on vehicles
sold in the U.S.
Vehicles sold in Canada have the tire
information label in the glovebox, see
page 262.

230 Car care and technical informationCompact spare tireThe compact spare is light and easy to
handle when changing the tire. Its use is
only permitted when a standard tire has sus-
tained a puncture. The maximum life of the
tire is only 2000 miles (3,500 km).Do not exceed 50 mph (80 km/h) with the
compact spare fitted.The compact spare should be inflated to
60 psi (420 kPa). Carry the punctured tire in
the spare-wheel well under the luggage-
compartment floor.
Have the standard tire repaired and refitted
as soon as possible (see also page 170).The spare tire, together with the jack, front
towrope attachment eye and toolkit, is
stowed away underneath the luggage-
compartment floor.
NOTICETo avoid damaging a punctured alloy
wheel it can be placed outside up in the
spare-wheel well but
only
while driving to
the closest dealer.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 123 and 126.
