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.

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.
