REMEMBER.... High speed driving can be dangerous and may damage
your tires.AND.... When driving at highway speeds, correct inflation
pressure is especially important.
INSPECT YOUR TIRES, DO NOT DRIVE ON A DAMAGED TIRE
OR WHEEL
HAZARDS
Objects in the road, such as potholes, glass, metal, rocks, wood, debris
and the like, can damage a tire and should be safely avoided. Unavoid-
able contact with such objects should prompt a thorough tire inspection.
BFGOODRICH TIRES
35
Anytime you see any damage to your tires or wheels, replace with the
spare at once and immediately visit any BFGoodrich® tire retailer.
IMPACT DAMAGE
A tire impacted by a road hazard (curb, pothole, debris) may be damaged
but not have visible signs of damage on its surface. A tire damaged by an
impact may sustain a sudden failure a day, week, or even months later.
You may not recall hitting an object that damaged or injured your tires.
Air loss, unusual tire wear, localized wear or vibrations can also be signs
of internal tire damage.
If you suspect any damage to your tire or wheel from an impact with a
curb, pothole, debris on the road or any other road hazard, or if you feel
or hear any unusual vibration, replace with a properly inflated spare at
once and immediately visit any qualified tire technician.
INSPECTION
When inspecting your tires, including the spare, check the air pressures.
If the pressure check indicates that one of your tires has lost pressure of
two pounds or more, look for signs of penetration, valve leakage or wheel
damage that may account for the air loss.
Always look for bulges, cracks, cuts, penetrations and abnormal tire
wear, particularly on the edges of the tire tread, which may be caused
by misalignment or underinflation. If any such
All tires will wear out faster when subjected to high speeds as well as
hard cornering, rapid starts, sudden stops, frequent driving on roads
which are in poor condition, and off road use. Roads with holes and rocks
or other objects can damage tires and cause misalignment of your vehicle.
When driving on such roads, drive carefully and slowly, and before
driving again at normal or highway speeds, examine your tires for any
damage, such as cuts, bulges, penetrations, unusual wear patterns, etc.
WEAR BARS
BFGoodrich® tires contain “Wear-Bars” in the grooves of the tire tread
which show up when only 2/32 nds of an inch (1.6 mm) of tread is
remaining. At this stage, your tires must be replaced. Tires worn beyond
this stage are extremely dangerous.
DO NOT OVERLOAD - DRIVING ON ANY OVERLOADED TIRE IS
DANGEROUS
BFGOODRICH TIRES36
The maximum load rating of your tires is molded on the tire sidewall. Do
not exceed this rating. Follow the loading instructions of the manufac-
turer of your vehicle and this will ensure that your tires are not
overloaded. Tires which are loaded beyond their maximum allowable
loads for the particular application will build up excessive heat that may
result in sudden tire destruction.
Do not exceed the gross axle weight rating for any axle on your vehicle.
TRAILER TOWING
If you anticipate towing a trailer, you should visit any BFGoodrich® tire
retailer for advice concerning the correct size tire and pressures. Tire size
and pressures will depend upon the type and size of trailer and hitch
utilized, but in no case must the maximum cold inflation pressure or tire
load rating be exceeded. Check the tire decal and the owner ’s manual
supplied by the manufacturer of your vehicle for further recommenda-
tions on trailer towing.
WHEEL ALIGNMENT AND BALANCING ARE IMPORTANT FOR
SAFETY AND MAXIMUM MILEAGE FROM YOUR TIRES CHECK
HOW YOUR TIRES ARE WEARING AT LEAST ONCE EACH
MONTH
If your tires are wearing unevenly, such as the inside shoulder of the tire
wearing faster than the rest of the tread, or if you detect excessive
vibration, your vehicle may be out of alignment or balance. These
conditions not only shorten the life of your tires but adversely affect the
handling characteristics of your vehicle, which could be dangerous. If
you detect irregular wear or vibration, have your alignment and balance
checked immediately. Tires which have been run underinflated will show
more wear on the shoulders than in the center of the tread.
TIRE MIXING
BFGoodrich® tires are radial tires and for best performance it is recom-
mended that the same size and type of tire be used on all four wheel
positions. Before mixing tires of different types in any configuration on
any vehicle, be sure to check the vehicle manufacturer ’s Owner‘s Manual
for its recommendations.
It is especially important to check the vehicle manufacturer ’s owner ’s
manual when mixing, matching or replacing tires on 4-wheel drive
vehicles, as this may require special precautions.
BFGOODRICH TIRES
37
BFGOODRICH® DOES NOT RECOMMEND MIXING SELF SUPPORT-
ING STRUCTURE (SSS) TIRES WITH NON-SSS TIRES OTHER THAN
THE TEMPORARY USE OF THE SPARE TIRE.
WINTER DRIVING
Tires which meet the Rubber manufactures Association (RMA) definition
of snow tires are marked M/S, M&S. On such tires, this designation is
molded into the sidewall. Tires without this notation are not recom-
mended for winter driving.While All-Season tires are designed to provide reliable
performance in some winter conditions, the use of four
(4) winter tires is recommended for optimum perfor-
mance. Tires designated for use in severe winter condi-
tions are marked on at least one sidewall with the letter
“M” and “S” plus a pictograph of a mountain with a snowflake on it.
TIRE ROTATION AND REPLACEMENT
To obtain maximum tire wear, it may be necessary to rotate your tires. Refer
to your vehicle owner ’s manual for instructions on tire rotation. If you do
not have an owner‘s manual for your vehicle, BFGoodrich® recommends
rotating your tires every 6,000 to 8,000 miles (10,000 to 12,000 km).
Monthly inspection for tire wear is recommended. Your tires should be
rotated at the first sign of irregular wear, even if it occurs before 6,000
miles (10,000 km). This is true for all vehicles.
When rotating tires with a directional tread pattern, observe the arrows
molded on the sidewall which show the direction the tire should turn.
Care must be taken to maintain the proper turning direction.
Some Tire Pressure Monitoring systems (TPMS) may not recognize that a
tire has been moved to a different position on your vehicle. Make certain
that your TPMS system is reset, if necessary, so as to correctly identify the
location of each tire on your vehicle. Refer to your vehicle owner ’s
manual or your vehicle dealer.
Determine whether rotated tires require tire inflation adjustment as front
and rear position tire pressure may vary according to the vehicle manufac-
turer ’s specification due to the actual load on that wheel position. Some
vehicles may have different sized tires mounted on the front and rear axles,
and these different sized tires have rotation restrictions. Always check the
vehicle owner ’s manual for the proper rotation recommendations.
BFGOODRICH TIRES

FULL-SIZE SPARE
Full-size spare tires (not temporary spares) of the same size and construc-
tion should be used in a five (5) tire rotation. Always check the inflation
pressure of the full-size spare immediately before incorporating it into
rotation. Follow the vehicle manufacturer ’s recommended pattern for
rotation, or if not available, see a qualified tire technician.
REPLACEMENT OF TWO (2) TIRES
It is recommended that all four (4) tires are replaced at the same time.
However, whenever only two tires are replaced, the new ones should be
put on the rear. The new tires, with deeper tread, may provide better grip
and water evacuation in wet driving conditions.
CUSTOMIZATION OF TIRES, WHEELS, OR SUSPENSION ON
SUVS AND LIGHT TRUCKS
Due to their size, weight and higher center of gravity, vehicles such as
SUVs and light trucks do not have the same handling characteristics as
automobiles. Because of these differing characteristics, failure to operate
your SUV/truck in a proper and safe manner can increase the likelihood
of vehicle rollover. Modifications to your SUV/truck tire size, tire type,
wheels or suspension can change its handling characteristics and further
increase the likelihood of vehicle rollover. Whether your SUV/truck has
the original equipment configuration for tires, wheels and suspension or
whether any of these items have been modified, always drive safely,
avoid sudden, sharp turns or lane changes and obey all traffic laws.
Failure to do so may result in loss of vehicle control leading to an accident
and serious injury or death.
TIRE ALTERATIONS
Do not make or allow to be made any alterations on your tires.
Alterations may prevent proper performance, leading to tire damage
which can result in an accident. Tires which become unserviceable due to
alterations such as trueing, whitewall inlays, addition of balancing or
sealant liquids, or the use of tire dressing containing petroleum distillates
are excluded from warranty coverage.

REPAIRS - WHEREVER POSSIBLE, SEE YOUR BFGOODRICH®
TIRE RETAILER AT ONCE
If any BFGoodrich® tire sustains a puncture, have the tire demounted
and thoroughly inspected by any BFGoodrich® tire retailer for possible
damage that may have occurred.
A tread area puncture in any BFGoodrich® passenger or light truck tire
can be repaired provided that the puncture hole is not more than 1/4” in
diameter, not more than one radial cable per casing ply is damaged, and
the tire has not been damaged further by the puncturing object or by
running underinflated. Tire punctures consistent with these guidelines
can be repaired by following the Rubber Manufacturers Association
(RMA) recommended repair procedures.
TIRE REPAIRS
Repairs of all tires must be of the combined plug and inside patch type.
Plug only repairs are improper.A tire should be removed from the rim
and inspected prior to repair. Any tire repair done without removing the
tire from the rim is improper. An improperly repaired tire will cause
further damage to the tire by either leaking air or allowing air, moisture
and contaminants to enter the structure of the tire. An improperly
repaired tire can fail suddenly at a later date.
Never repair a tire with less than 2/32 nds of an inch tread remaining. At
this tread depth, the tire is worn out and must be replaced.
TEMPORARY SPARE TIRES
When using any temporary spare tire, be sure to follow the vehicle
manufacturer ’s instructions.
READING THE DOT
DOT XXXX XXXX XXX (prior to August 2000)
DOT XXXX XXXX XXX (1990-1999)
DOT XXXX XXXX XXXX (after July 2000)
THE DOT
The “DOT” symbol certifies tire manufacturer ’s compliance with U.S.
Department of Transportation tire safety standards. Next to the symbol is
the tire identification or “serial number”. The first two characters identify
the plant where the tire was manufactured. The next two characters
BFGOODRICH TIRES
40
reflect the tire size. The following one to four digits may be used at the
tire manufacturer ’s option as a descriptive code. The last three characters
are numbers identifying the week and year of manufacture. (Example:
“O25” means second week of the year of decade, eg.: 1995, 1985, etc.)
Tires produced after July 2000 have an additional digit to identify a given
decade. For example, 2800 means the tire was produced during the 28th
week of 2000; 0201 during the 2nd week of 2001. If the last digits of your
DOT number contain three numeric characters consult a qualified tire
technician to determine the year and decade of manufacture.
STORAGE
Tires contain waxes and emollients to protect their outer surfaces from
ozone and weather checking. As the tire rolls and flexes, the waxes and
emollients continually migrate to the surface, replenishing this protection
throughout the normal use of the tire. Consequently, when tires sit
outdoors, unused for long periods of time (a month or more) their
surfaces become dry and more susceptible to ozone and weather check-
ing and the casing becomes susceptible to flat spotting.
For this reason, tires should always be stored in a cool, dry, clean,
indoor environment. If storage is for one month or more, eliminate the
weight from the tires by raising the vehicle or by removing the tires
from the vehicle. Failure to store tires in accordance with these
instructions could result in damage to your tires or premature aging of
the tires and sudden tire failure.
When tires are stored, be sure they are placed away from sources of heat
and ozone such as hot pipes and electric generators. Be sure that surfaces
on which tires are stored are clean and free from grease, gasoline or other
substances which could deteriorate the rubber.(Tires exposed to these
materials during storage or driving could be subject to sudden failure.)
FOLLOW THESE MOUNTING RECOMMENDATIONS
Tire changing can be dangerous and must be done by professionally
trained persons using proper tools and procedures as specified by the
Rubber Manufacturers Association (RMA).
Your tires should be mounted on wheels of correct size and type and
which are in good, clean condition. Wheels that are bent, chipped, rusted
(steel wheels) or corroded (alloy wheels) may cause tire damage. The
inside of the tire must be free from foreign material. Have your retailer
check the wheels before mounting new tires. Mismatched tires and rims
BFGOODRICH TIRES
41
can explode during mounting. Also, mismatched tires and rims can result
in dangerous tire failure on the road. If a tire is mounted by error on the
wrong-sized rim, do not remount it on the proper rim - scrap it. It may
have been damaged internally (which is not externally visible) by having
been dangerously stretched and could fail on the highway.
Old valves may leak. When new tubeless tires are mounted, have new
valves of the correct type installed. Tubeless tires must only be
mounted on wheels designed for tubeless tires i.e., wheels which have
safety humps or ledges.
It is recommended that you have your tires and wheels balanced. Tires
and wheels which are not balanced may cause steering difficulties, a
bumpy ride, and irregular tire wear.
Be sure that all your valves have suitable valve caps. The valve cap is
the primary seal against air loss.
SERVICE LIFE FOR PASSENGER CAR AND LIGHT TRUCK
TIRES INCLUDING SPARE TIRES
The following recommendation applies to passenger car and light truck
tires. Tires are composed of various types of material and rubber
compounds, having performance properties essential to the proper
functioning of the tire itself. These component properties evolve over
time. For each tire, this evolution depends upon many factors such as
weather, storage conditions, and conditions of use (load, speed, inflation
pressure, maintenance etc.) to which the tire is subjected throughout its
life. This service-related evolution varies widely so that accurately
predicting the serviceable life of any specific tire in advance is not
possible.
That it is why, in addition to regular inspections and inflation pressure
maintenance by consumers, it is recommended to have passenger car and
light truck tires, including spare tires, inspected regularly by a qualified
tire specialist, such as a tire dealer, who will assess the tire’s suitability for
continued service. Tires which have been in use for 5 years or more
should continue to be inspected by a specialist at least annually.
Consumers are strongly encouraged to be aware not only of their tires’
visual condition and inflation pressure but also of any change in dynamic
performance such as increased air loss, noise or vibration, which could be
an indication that the tires need to be removed from service to prevent
tire failure.
