TIRE QUALITY GRADES
The following tire grading categories were established by the Na-
tional Highway Traffic Safety Administration. The specific grade
rating assigned by the tire’s manufacturer in each category is shown
on the sidewall of the tires on your vehicle.
All passenger vehicle tires must conform to Federal safety require-
ments in addition to these grades.
Treadwear
The 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 one-half times as well on the government 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.
Traction Grades
The Traction grades, from highest to lowest, are AA, A, B, and C.
These grades represent the tire’s ability to stop on wet pavement, as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.
WARNING!
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration, corner-
ing, hydroplaning, or peak traction characteristics.

Ply Composition and Materials:The actual number of plies in the
sidewall and tread area and the generic name(s) of their cord material(s)
are marked on at least one sidewall. For example:
• TREAD 2 PLY POLYESTER + 2 STEEL
• SIDEWALL 2 PLY POLYESTER
Radial: Radial ply tires will have the word radialon at least one
sidewall. An “R” in the tire size designation also indicates radial ply
construction.
Tubeless or Tube Type: Tires are marked as either “tubeless” or “tube
type,” whichever is applicable, on at least one sidewall.
UNIFORM TIRE QUALITY GRADING
The Uniform Tire Quality Grading (“UTQG”) standards are intended to
assist you in making an informed choice in your purchase of passenger
car tires by providing information indicating relative performance of
these tires in the areas of tread wear, wet braking traction (straight-
ahead), and temperature resistance. All passenger car tires must conform
to federal safety requirements in addition to these grades.
Treadwear
The 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 one half
(1 1/2) times as well on the government 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
variation in driving habits, service practices and differences in road
characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. Warning: The traction grade assigned to a tire is
based on straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning, or peak traction characteristics.

STORING YOUR TIRES
When storing your tires for any extended period of time, be sure to
thoroughly clean your tires with a tire brush, soap, and water to remove
any dirt, salt, and brake dust from the tires. If you are storing your tires
still mounted on the wheels, use a wheel brush and approved wheel
cleaner to clean your wheels. Then dry the wheels and tires with a towel
and allow them to fully dry. DO NOT apply any tire dressings while
storing your tires. Tire compounds are made to resist weather cracking
and ozone damage. Place each clean and dry tire in an airtight plastic bag
and seal the bag with tape to help reduce oil evaporation. Store your tires
out of direct sunlight and somewhere that is well shielded from the
elements, like a climate-controlled room or dry basement. Storing the
tires in a garage or shed usually exposes the tires to a wide range of
temperatures as well as precipitation and humidity. Keep the tires away
from sources that emit ozone like electric motors that use contact brushes,
furnaces, sump pumps, etc. Although tires will still age regardless of how
they are stored, these precautions will help slow the aging process and
reduce the damage to your tires.
SPEED LIMITS
WARNING!
Operating your vehicle in excess of the posted speed limit or the
maximum speed allotted by driving conditions has the potential to
be dangerous. Higher driving speeds create excessive heat buildup
in a tire, leading to a possible tire failure.
TIRE SPINNING
WARNING!
Spinning a tire to get a stuck vehicle out of mud, ice, snow, sand, or
wet grass can be potentially dangerous. A spinning tire at a
speedometer reading above 55 km/h (35 mph) can be capable of
disintegrating a tire with explosive force. In some circumstances, a
tire may be spinning at twice the speed displayed on the
speedometer. This can cause serious injury or death to you, a
passenger, or bystander. Never spin a tire above 55 km/h (35 mph).

MAX LOAD AND INFLATION
The maximum load and inflation pressure is marked on the tire sidewall
in English and metric units.
PLY COMPOSITION AND MATERIALS
The number of plies and their generic composition of cord materials in
the sidewall and tread areas can be found on at least one sidewall of a
tire.
RADIAL MARKING
A radial ply tire will have the word “radial” marked on at least one
sidewall. An “R” found in the tire size marking also refers to the tire
being a radial ply tire.
UNIFORM TIRE QUALITY GRADING SYSTEM (UTQG)
The Uniform Tire Quality Grading Standards (UTQG) were created to
help you make an informed decision when purchasing passenger car tires
by providing relative information about a tire’s treadwear, traction, and
temperature characteristics. Here is a breakdown of the different catego-
ries that the UTQG grades:
TREAD WEAR
The tread wear grade is a comparative 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 graded150would wear one and a
half (1½) times as well on the government 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.
TRACTION
The traction grades, from highest to lowest, are AA, A, BandC. Those
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specific government test surfaces of
asphalt and concrete. A tire marked C may have poor traction perfor-
mance.

their use and may vary due to driving habits, service practices,
differences in road characteristics, and climate.
• Traction - The traction grades from highest to lowest are AA, A, B, and
C, and they represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete.
m NOTICE!
The traction grade assigned to tires is based on locked braking (straight
ahead) traction tests and does not include cornering (turning) traction.
• Temperature - 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 conditions on a
specified indoor laboratory test wheel. Sustained high temperatures
can cause the materials of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden tire failure. The grade C
corresponds to a level of performance that all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No. 139. Grades
B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
WARNING!
The temperature grade 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
buildup and possible tire failure. This can cause an accident, which
could lead to serious personal injury or death.
• DOT Quality Grades - All passenger car tires must conform to federal
requirements in addition to these grades.
