DEPARTMENTOF TRANSPORTATION UNIFORM
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
ederal
safety
require-
ments
in
addition
to
these
grades.
Treadwear
The
readwear
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
raction
grades,
from
highest
to
lowest,
are
AA,
A,
B,
and
C.

These
grades
represent
the
tir

e’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.

TIRE SPINNING
Do not spin wheels in excess of 35 mph (55 km/h) as indicated on the
speedometer. Excessive speed in a free-running, unloaded tire can cause
it to “explode” from centrifugal force. The energy released by such an
explosion is sufficient to cause serious physical injury or death. Never
allow anyone to stand near or behind the spinning tire.
When in mud, sand, snow, ice or other slippery conditions, do not engage
in excessive wheel spin. Accelerating the motor excessively, particularly
with automatic transmission vehicles, may cause a drive tire that has lost
traction to spin beyond its speed capability. This is also true when
balancing a drive tire/wheel assembly on the vehicle using the vehicle
engine to spin the tire/wheel assembly.
HIGH SPEED DRIVING CAN BE DANGEROUS
Correct inflation pressure is especially important.However, at high
speeds, even with the correct inflation pressure, a road hazard, for
example is more difficult to avoid and if contact is made, has a greater
chance of causing tire damage than at a lower speed. Moreover, driving
at high speed reduces the reaction time available to avoid accidents and
bring your vehicle to a safe stop.
If you see any damage to a tire or wheel, replace it with the spare at
once and visit a participating BFGoodrich Tire Retailer.
Exceeding the maximum speeds shown on the following page for each
type of BFGoodrich tire will cause the tire to build up excessive heat
which can cause tire damage that could result in sudden tire destruction
and rapid air loss. Failure to control a vehicle when one or more tires
experience a sudden air loss can lead to an accident.
In any case, you should not exceed reasonable speeds as indicated by
the legal limits and driving conditions.

HIGH PERFORMANCE, LOW ASPECT RATIO TIRES
Many new vehicles come equipped from the factory with high perfor-
mance and/or low aspect ratio tires. Generally, these tires provide
increased vehicle handling capability, but may also have numerous
engineering performance trade-offs associated with their designs.
•Low aspect ratio tires, with reduced sidewall height, may be more
susceptible to damage from potholes, road hazards, and other objects
such as curbs. This is true for the wheels as well. Therefore, as with all
other tires, it is important to drive with care and maintain proper
inflation pressure and load conditions. See “Tire Inflation Pressure”
and “Tire Damage, Inspection and Service Life” in this manual.
• Some

sports
cars
and
other

performance
enhanced
vehicles,

including
sedans
and
light
trucks/SUVs,
may
be
originally
equipped

with
high
performance
tires
that
are
more
optimized
for
warmer

weather
use.
Colder,
inter
weather
traction
may
be
reduced
for
these

types
of
tires.
Winter
tires
may
be
recommended
by
the
vehicle

manufactur

er
for
colder
weather
application.
See
“Winter
Tires,”
the

next
section
in
this
manual.
• High performance tires may also wear more quickly, ride more firmly,
and produce more noise during operation.
Consult your vehicle owner ’s manual and tire information placard, or a
qualified tire service professional, for more information and specifics
regarding these types of tires.
WINTER TIRES
WARNING!
Winter
driving
presents
special
challenges
for
vehicle
mobility.
The

use
of
inter
tires
(including
studs
and
chains)—while
improving

traction
performance
in
snow
and
ice—requires
special
care
with

regard
to
acceleration,
braking,
cornering,
and
speed.
It
is
important

to
drive
with
care,
not
only
on
snow
and
ice,
but
on
dry
and
wet

roads
as
well.
BRIDGESTONE® - FIRESTONE®
In

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.

WARNING!
Falken does not recommend the use of mixing different speed
ratings on a vehicle. This can cause poor handling and
unpredictable steering.
HIGH PERFORMANCE, LOW ASPECT RATIO TIRES
Various new vehicles come equipped with high performance and/or low
aspect ratio tires from the factory. These tires generally provide increased
vehicle handling characteristics, but may also have engineering perfor-
mance trade-offs related with their designs. Low aspect ratio tires have
reduced sidewall heights and may be more vulnerable to damage from
road hazards, potholes, and other objects, like curbs. Your vehicle’s
wheels are susceptible to these same dangers as well. Some vehicles may
be originally equipped with high performance tires that are designed for
warmer weather use reducing traction in colder, winter weather condi-
tions. High performance tires also pose the possibility of wearing more
quickly, giving a stiffer ride, and producing louder noise than standard
all-season tires during operation. Refer to your vehicle owner ’s manual,
tire information placard,
WINTER TIRES
Falken recommends all four tires be replaced when replacing your
original equipment tires and installing winter tires for the winter months.
WARNING!
Never use just two winter tires. It could lead to adverse handling,
loss of control, which could cause serious injury or death.

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.

WARNING!
The traction grades assigned to this tire is based on straight ahead
braking traction tests, and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
TEMPERATURE
The temperature grades are A(the highest), B, andC, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions or on a specified indoor
laboratory test wheel. Sustained high temperature can cause the material
of the tire to degenerate and reduce in tire life, and excessive temperature
can lead to sudden tire failure. The grade Ccorresponds to a level of
performance which all passenger car tires must meet under the Federal
Motor Vehicle Safety Standard No.109. Grades Band Arepresent higher
levels of performance on the laboratory test wheel than minimum
required by law.
WARNING!
The temperature grade for each tie is established for a tire that is
properly inflated and not overloaded. Excessive speed, under-
inflation, or excessive loading either separately or in combination,
can cause heat buildup and possible tire failure.
