BFGOODRICH TIRE
Replacement of Two Tires
All four tires should be replaced at the same time. However, if only 
two tires are replaced, the new ones should be put on the rear. 
Deeper tread tires on the rear axle provide better handling, wet grip 
and evacuate water, thereby helping to avoid oversteer and loss of 
vehicle stability on wet surfaces. Deeper tread tires on the front axle \
can improve wet straight line braking and stopping distance. If only two\
 
tires are being replaced, BFGoodrich generally recommends they be 
installed on the rear axle in the absence of a tire service professional’s 
recommendation or consumer’s preference to the contrary.
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 different characteristics, failure to 
operate your SUV or truck in a proper and safe manner can increase 
the likelihood of vehicle rollover. Modifications to your SUV or truck 
tire size, tire type, wheels or suspension can change your vehicle’ s 
handling characteristics and further increase the likelihood of vehicle \
rollover. Whether your SUV or 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 
that can result in an accident. Tires that become unserviceable due 
to alterations such as truing, whitewall inlays, addition of balancing

Speed Rating: The tire’s speed rating is void if the tire is repaired, 
retreaded, damaged, abused, or otherwise altered from its original 
condition. Thereafter, it should be treated as a non-speed rated tire. 
See “Tire Speed Ratings” in this manual.
Improper repair voids the tire Limited Warranty. See “Limited 
Warranty” in this manual.
RFT (Run-Flat Technology) Tires: In addition to the above, there are 
recommendations specific to the repair of RFT tires; see “RFT Tires 
with Run-Flat Technology” in this manual.
Tire Mounting and Other Servicing 
 SAFETY WARNING
Removing and replacing tires on wheels can be dangerous. Attempting 
to mount tires with improper tools or procedures may result in a tire 
explosion causing serious personal injury or death. This is only a job 
for a qualified tire service professional. Never perform tire service 
procedures without proper training, tools, and equipment.
This manual is not intended to provide proper training or service 
procedures for tire mounting, demounting, balancing, rotation, 
or repair. Please leave these tasks to qualified tire service 
professionals. For your safety and that of others:
•
 Always stand well clear of any tire mounting operation. This is 
especially important when the service operator inflates the tire. If 
the tire has been improperly mounted, it may burst with explosive 
force causing serious personal injury or death.
•
 Tires must match the width and diameter requirements of the 
wheels. For example, 16 inch diameter tires must only be mounted 
to 16 inch diameter wheels. Radial tires must only be mounted to 
wheels approved for radial tires.
•
 Wheels must be free of cracks, dents, chips, and rust. Tires must 
be free of bead damage, cuts, and punctures.
•
 Never inflate a tire beyond 40 psi (275 kPa) to seat the beads. Be 
absolutely certain beads are fully seated before adjusting inflation 
pressure to the level recommended for vehicle operation.

size mounted on the front versus the rear axles, and these different 
tires have rotation restrictions. Always check the vehicle owner’s 
manual for the proper rotation recommendations.
Full-Size Spare
Full-size spare tires (not temporary spares) of the same size and 
construction should be used in a five-tire rotation and should be 
inspected by a tire professional during routine tire inspection. Always 
have spare tires inspected before installation. Tires are composed 
of various types of rubber compounds and other materials having 
performance properties essential to the proper functioning of the tire. \
These component properties change over time. Always check the 
inflation pressure of the full-size spare and look for any indication   of 
cracking or other damage immediately before incorporating the spare 
into rotation. If you see any damage, or if the tire is underinflated, do 
not resume driving with that tire unless you have no other option, in 
which case you should drive only as slowly as is safely possible in the \
traffic conditions until you can both get the spare tire properly inflated 
and have it checked by a tire professional to ensure that it is safe 
to use. Follow the vehicle manufacturer’s recommended pattern for 
rotation. If such a recommendation is unavailable, see a qualified  
tire professional.
 
Replacement of Two Tires
All four tires should be replaced at the same time. However, if only 
two tires are replaced, the new ones should be put on the rear. 
Deeper tread tires on the rear axle provide better handling, wet grip 
and evacuate water, thereby helping to avoid oversteer and loss of 
vehicle stability on wet surfaces. Deeper tread tires on the front axle \
can improve wet straight line braking and stopping distance. If only 
two tires are being replaced, Michelin generally recommends they be 
installed on the rear axle in the absence of a tire service professional’ s 
recommendation or consumer’s preference to the contrary.

limitation, misalignment, defective brakes, defective shock 
absorbers or struts, or improper rims;
 - fire, chemical corrosion, vandalism, wrecks, theft, running while 
flat, underinflated or overinflated or abuse during servicing;
 - road hazard injuries (including, without limitation, due to nails, glass, metal objects) or other penetrations or snags, bruises 
or impact damage (other than for Run Flat and PNCS tires 
specifically covered under the Road Hazard policy);
 -running on a dynamometer.
Additional Exclusions: •
 Tires on any vehicle registered or operated outside the United 
States of America or Canada;
•
 Tires transferred from the vehicle on which they were originally 
installed by a vehicle manufacturer or authorized Pirelli dealer;
•
 Additional tires that are not independently subject to a   
warranty claim;
•
 Tires which have been inflated with anything other than air or 
nitrogen;

Owner’s Responsibilities
The owner is responsible for proper tire care and maintenance. 
Maintain the recommended tire pressure by checking the tire pressure 
monthly and before long trips with an accurate pressure gauge. Using 
vehicle manufacturer suggestions based on load will improve tire life 
and your satisfaction with the tires.

traction is reduced during rainfall and winter road conditions. Visual tire 
inspection therefore becomes more crucial as the tires wear out.
Hard Braking
You must inspect your tires after any hard braking situations or after 
tires have slid on the pavement. This can cause a flat spot or other 
damage to the tread of the tire.
Spinning•
 Do not allow tires to spin at speeds greater than 35 mph 
(56.3km/h) if vehicle becomes stuck.
•
 Do not stand behind a spinning tire while attempting to push  
a vehicle.
Speed and force can cause a tire to disintegrate and explode and may
cause property damage and/or personal injury.
Recommended Tire Rotation
Front and rear tires perform differently and consequently YOKOHAMA
recommends tire rotation to ensure even wear and lengthen tread life. 
In the absence of the vehicle manufacturer’s instruction, YOKOHAMA 
recommends that its tires be rotated every 7,500 miles (12,000 km) for 
normal applications.
WARNING SERIOUS INJURY MAY RESULT FROM: •
 Tire failure due to underinflation, overinflation, or overloading – 
follow owner’s manual or tire placard in vehicle.
•
 Explosion of the tire/rim assembly due to improper mounting –  
only specially trained persons should mount tires.
THERE IS DANGER IN INSTALLING A TIRE OF ONE RIM
DIAMETER ON A RIM OF A DIFFERENT RIM DIAMETER •
 Always replace a tire on a rim with another tire of exactly the same 
rim diameter designation and suffix letters. For example, a 16 inch 
tire goes with a 16 inch rim. Never mount a 16 inch size diameter 
tire on a 16.5 inch rim.
