DEPARTMENT OF TRANSPORTATION UNIFORM TIRE
QUALITY GRADES
The following tire grading categories were established by the National
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
re
quirements 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
gr
ades 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
br
aking traction tests, and does not include acceleration,
cornering, 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
R
adial: Radial ply tires will have the word "radial" on at least one
s
idewall. An “R” in the tire size designation also indicates radial ply
construction.
Tubeless or Tube Type: T
ires 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
th
e 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
gr
ades represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete.

NOTE:

The traction grade assigned to a tire is based on straight-ahead
br
aking 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
th
oroughly 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
TIRE SPINNING
WARNING!
Operating your vehicle in excess of the posted speed limit or the
ma
ximum 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.
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
di

sintegrating 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
(3

5 mph).

MAX LOAD AND INFLATION
The maximum load and inflation pressure are marked on the tire
si
dewall in english and metric units.
PLY COMPOSITION AND MATERIALS
The number of plies and their generic composition of cord materials in
th
e 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
si
dewall. 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
he
lp 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 categories 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
government test course. For example, a tire graded 150 would 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, B and C. 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 performance.

tions of their use and may vary due to driving habits, service prac-
tices, differences in road characteristics, and climate.
• Traction - The traction grades from highest to lowest are AA, A, B,
a
nd 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.
• Temperature - The temperature grades are A (the highest), B, and C,
r
epresenting 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 tempera -
tures can cause the materials of the tire to degenerate and reduce tire
li
fe, 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.
• D OT Quality Grades - All passenger car tires must conform to
f
ederal requirements in addition to these grades. CAUTION!

The traction grade assigned to tires is based on locked braking
( s

traight ahead) traction tests and does not include cornering
(turning) traction.
WARNING!
The temperature grade is established for a tire that is properly
in
flated 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.
