BFGOODRICH TIRE
Trailer Towing
If you anticipate towing a trailer, you should visit your BFGoodrich tire
retailer for advice about the correct tire size and pressures. Tire size
and pressures will depend on 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 information placard
that came on your vehicle, (located in the vehicle’s door jamb, inside
the fuel hatch, or on the glove compartment door) and the owner’s
manual supplied by the manufacturer of your vehicle for further
recommendations 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 excessi\
ve
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. Read
and follow the instructions on tire rotation and replacement below.

• Use valve caps to keep the valves clear of debris and to help
guard against inflation pressure loss.
Tips For Safe Loading SAFETY WARNING
Driving your vehicle in an overloaded condition is dangerous
Overloading causes excessive tire heat build-up and internal structural
damage. This can cause a tire failure, even at a later date, which
could lead to serious personal injury or death. Consult the vehicle tire
information placard, certification label, and owner’s manual for the
recommended vehicle load limits and loading recommendations.
•
Always keep the vehicle manufacturer’s recommended inflation
pressure in all your tires, including the spare. Check their pressure
monthly and before long trips or carrying extra weight.
•
Never exceed the maximum load rating stamped on the sidewall of
your tire.
•
Never exceed the gross vehicle weight rating (GVWR) or front/rear
gross axle weight ratings (GAWR) of your vehicle.
•
Consult your vehicle owner’s manual for load recommendations
and special instructions (such as for trailer/towing and snow
plow installations).
Tire Damage, Inspection and Service Life
Evaluation and maintenance of your tires is important to their
performance and the service they provide to you. Over time and/
or through use, the condition of a tire can change from exposure to
everyday road conditions, the environment, damaging events such as
punctures, and other external factors.
SAFETY WARNING
Driving on damaged tires is dangerous. A damaged tire can suddenly
fail causing serious
personal injury or death. Have your tires regularly
inspected by a qualified tire service professional.

flat operation is pressure at or below 10 psi (70 kPa); however, some
vehicle manufacturers may have established a different pressure
limit. Consult your vehicle owner’s manual for the details of your
TPMS. Once the TPMS has indicated that a tire has reduced inflation
pressure, the run-flat mode of operation has commenced. During this
phase of operation, please follow these instructions:•
Reduce speed as much as safely and reasonably possible; do
not exceed 50 mph (80 km/h). The greater the speed, the less
distance the tire can travel.
•
Avoid abrupt or aggressive acceleration, braking, or cornering
maneuvers as much as safely and reasonably possible. Pot
holes and other road hazards should be avoided. Careful driving
limits potential damage to the tire, wheel, and vehicle.
•
Proceed to a safe and convenient location for tire service
as soon as possible. Take note of your mileage; your operation
distance is limited. See “Distance—How Far You Can Drive,” the
next section in this manual.
•
If an unusual vibration or vehicle handling difficulty arises,
stop driving as soon as safely and reasonably possible. The
tire may be about to suddenly fail. Release the accelerator and
gradually reduce speed. The tire will need to be replaced before
proceeding.
•
If towing a trailer, stop driving as soon as safely and
reasonably possible. In this condition, it is potentially dangerous
to operate a vehicle/trailer combination. If possible, disconnect the
trailer and proceed as noted above. Do not continue to tow any
trailer until proper tire service or replacement has been performed.
•
Do not touch a tire recently run-low or run-flat (it may be very
hot). Allow the tire to cool before handling.
Distance—How Far You Can Drive
Factors affecting run-flat or low tire pressure operating distance include
vehicle speed, load, and maneuvering; the amount of inflation pressure
loss; the extent of any tire damage; and ambient temperature.
The tire may be marked on the sidewall with run-flat or low tire
pressure operating speed and/or distance limitations, which vary by tire\

must be inspected by any tire dealer at once. Use of a damaged tire
could result in sudden tire destruction.
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 you drive on such roads, drive on them carefully
and slowly, and before driving at normal or highway speeds, examine
your tires for any damage, such as cuts or penetrations.
Worn Out Tires Are Dangerous
Tires contain ‘Wear-Bars” in the grooves of the tire tread which show
up when only 2/32nds of an inch (1.6mm) tread is remaining. At this
stage, your tires must be replaced. Tires worn beyond this stage
are dangerous.
Do Not Overload
Driving On Any Overloaded Tire Is Dangerous
The maximum load rating of your tires is marked on the tire sidewall.
Do not exceed these ratings. Follow the loading instructions of the
manufacturer of your vehicle and this will insure that your tires are no\
t
overloaded. Tires which are loaded beyond their maximum allowable
loads for the particular application will build up excessive heat that m\
ay
result in sudden tire destruction.
Do not exceed the gross axle weight ratings for any axle on your
vehicle. TRAILER TOWING
If you anticipate towing a trailer, you should see any tire dealer for
advice concerning the correct size of 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 of
tire load rating be exceeded. Check the tire placard and the owner’s
manual supplied by the manufacturer of your vehicle for further
recommendations on trailer towing.

Tires loaded beyond their maximum allowable loads for the particular
application will build up excessive heat that may result in sudden tire \
failure and an accident. 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 your Michelin tire
retailer for advice about the correct tire size and pressures. Tire size
and pressures will depend on 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 information placard
that came on your vehicle, (located in the vehicle’s door jamb, inside
the fuel hatch, or on the glove compartment door) and the owner’s
manual supplied by the manufacturer of your vehicle for further
recommendations on trailer towing.
Self-Supporting Zero Pressure (ZP) Tires and Trailer Towing
Operation of ZP tires at low or zero air pressure with a trailer in tow
is dangerous and should be avoided. If the low pressure warning
indicator is activated when a trailer is in tow, stop, disconnect the
trailer, and do not continue to tow the trailer until the tire has been
properly repaired and re-inflated to the proper inflation. If the tire
cannot be properly repaired, it must be replaced with a new full-size,
matching ZP tire, and inflated to the proper inflation, before the trailer
can be safely towed again.

Wheel Alignment and Balancing Are Important for
Safety and Maximum Mileage from Your Tires.

TOWING OR USE OF SLIDE-IN TRUCK CAMPERS
If you are towing a trailer or using a slide-in truck camper, refer to your
vehicle Owner’s Manual.
WINTER (SNOW) TIRES
Winter driving presents special challenges for vehicle handling.
The use of winter tires, studs, and chains, while improving traction
performance in snow and ice, requires additional caution and care with
regard to 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.
• Traction is considerably reduced as snow tires approach 50%
tread wear, and replacement should be considered in order to
maintain effectiveness in heavy snow conditions.

It is not recommended that any light truck be operated at speeds in
excess of legal limits. However, if it is anticipated that sustained driving
at speeds in excess of 65 mph may be required, then the following
adjustments or recommendations should be followed:•
At speeds from 66 mph through 75 mph, cold inflation pressure
must be increased 10 psi above the recommended pressures for
the load being carried.
•
Do not exceed the maximum inflation pressure of the wheel (all
wheels have maximum allowable inflation pressures).
Replacement Tires for Light Trucks – P-Metric vs LT-Truck
Tire installers should exercise extreme caution when replacing tires on
light trucks.
The maximum load capacity stamped on the sidewall of a P-metric tire
is reduced by a factor of 1.1 when used on a light truck, a sport utilit\
y
vehicle, or a trailer.
