Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and satisfactory
op
eration of your vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
•
Economy
•
Tread Wear
•
Ride Comfort
S
afety
Both underinflation and overinflation affect the stability of the vehicle
a n
d can produce a feeling of sluggish response or over responsiveness
in the steering.
NOTE:
• Unequal tire pressures from side to side may cause erratic and
unpredictable steering response.
• Unequal tire pressure from side to side may cause the vehicle to drift
l
eft or right.
WARNING!
• Improperly inflated tires are dangerous and can cause collisions.
•
Underinflation increases tire flexing and can result in over -
h
eating and tire failure.
• Overinflation reduces a tire's ability to cushion shock. Objects
o
n the road and chuckholes can cause damage that result in tire
failure.
• Overinflated or underinflated tires can affect vehicle handling
a
nd can fail suddenly, resulting in loss of vehicle control.
• Unequal tire pressures can cause steering problems. You could
l
ose control of your vehicle.
• Unequal tire pressures from one side of the vehicle to the other
c
an cause the vehicle to drift to the right or left.
• Always drive with each tire inflated to the recommended cold
t
ire inflation pressure.

It is recommended to replace the two front tires or two rear tires as a
pair. Replacing just one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make sure that the wheel’s
specifications match those of the original wheels.
It is recommended you contact an authorized tire dealer or original
eq
uipment dealer with any questions you may have on tire
specifications or capability. Failure to use equivalent replacement tires
may adversely affect the safety, handling, and ride of your vehicle.
WARNING!
• Do not use a tire, wheel size, load rating, or speed rating other
t
han that specified for your vehicle. Some combinations of unap -
proved tires and wheels may change suspension dimensions and
pe
rformance characteristics, resulting in changes to steering,
handling, and braking of your vehicle. This can cause unpredict -
able handling and stress to steering and suspension compo -
nents. You could lose control and have a collision resulting in
se
rious injury or death. Use only the tire and wheel sizes with
load ratings approved for your vehicle.
• Never use a tire with a smaller load index or capacity, other than
w
hat was originally equipped on your vehicle. Using a tire with
a smaller load index could result in tire overloading and failure.
You could lose control and have a collision.
• Failure to equip your vehicle with tires having adequate speed
c
apability can result in sudden tire failure and loss of vehicle
control.
CAUTION!
Replacing original tires with tires of a different size may result in
fa
lse speedometer and odometer readings.

TIRE DISABLEMENT SAFETY WARNING
Any tire may fail as a result of an improperly repaired puncture,
i m
pact damage, improper inflation, overloading or other conditions
resulting from use or misuse. Tire failures, such as a rapid air loss or a
tread and belt detachment, may increase risk of injury or death and/
or property damage. To reduce the risk of a tire failure, BFGoodrich®
recommends you thoroughly read and follow the recommendations
in this BFGoodrich® Limited Warranty/Owner’s Manual, the vehicle
Owner’s Manual, tire placard information, and tire sidewall
information regarding safety warnings, proper tire use and
maintenance.
CONTROLLABILITY
CONTROLLING A VEHICLE WHEN A TIRE FAILURE OCCURS
If a tire failure occurs, you may hear a loud noise, feel a vibration,
a n
d/or the vehicle may pull toward the side of the failed tire. If
possible, step on the accelerator momentarily to maintain forward
momentum and ensure vehicle control.
It is important that you DO NOT BRAKE OR ABRUPTLY TURN
TH
E STEERING WHEEL.
Slowly remove your foot from the accelerator and hold the steering
wh
eel firmly while steering to remain in your lane. Once the vehicle
has slowed and is fully under control, apply the brakes gently; safely
pull over to the shoulder and come to a stop. Inspect the tires. If one
or more tires look flat or low, show detachment or other damage,
remove tire assembly and replace it with a properly inflated spare.
Bumps or bulges may indicate detachment within the tire body and
require inspection by a qualified tire technician.
WARNING!
DISREGARDING ANY OF THE SAFETY PRECAUTIONS AND/
OR
INSTRUCTIONS CONTAINED IN THIS MANUAL MAY
RESULT IN TIRE FAILURE OR EXPLOSION CAUSING
SERIOUS PERSONAL INJURY OR DEATH.

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
ne
w 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
an
d 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
IN
CLUDING SPARE TIRES
The following recommendation applies to passenger car and light
tr
uck 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 including 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.
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 five 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’
vi
sual 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.

TIRE FAILURE WHILE DRIVING
TIRE INFLATION PRESSURE
Tires need proper inflation pressure to operate effectively and
p e
rform as intended. Tires carry the vehicle, passenger, and cargo
loads and transmit the braking, acceleration, and turning forces. The
vehicle manufacturer recommends the inflation pressures for the tires
mounted on your vehicle.
WARNING!
It is not often that a properly maintained tire will “blow out”
wh
ile you are driving. More commonly, if inflation pressure is
lost, it will be gradual. If you do experience a blowout or sudden
tire failure, the following information should be helpful:
• When the failure occurs, you may hear a loud noise, feel a vibra -
t
ion, and/or the vehicle may pull toward the side of the failed
ti
re.
• DO NOT abruptly brake or turn.
•
Slowly remove your foot from the accelerator, hold the steering
w
heel firmly, and steer to maintain your lane position.
• Once the vehicle has slowed, apply the brakes gently.
•
Gradually pull over to the shoulder and come to a stop, as far off
t
he road as possible.
WARNING!
Driving on tires with improper inflation pressure is dangerous.
• Under-inflation causes excessive tire heat build-up and internal
s
tructural damage.
• Over-inflation makes it more likely for tires to be cut, punctured,
o
r broken by sudden impact.

TIRE SPEED RATINGS
Falken recommends replacing your tire(s) with the same speed rating
as
the original tires equipped on your vehicle.
It is okay to use a lower speed rated tire when using Winter tires.
Ho
wever, speeds should be reduced to match the tires new
“maximum” speed capability.
Any tire that is repaired, damaged, abused, altered from its original
st
ate or retreaded voids the speed rating on that particular tire and
should be considered a non-speed rated tire.
HIGH PERFORMANCE, LOW ASPECT RATIO TIRES
Various new vehicles come equipped with high performance and/or
lo
w aspect ratio tires from the factory. These tires generally provide
increased vehicle handling characteristics, but may also have
engineering performance 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 conditions. 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, or qualified tire service professional for more information
about these kinds of tires.
WINTER TIRES
Falken recommends all four tires be replaced when replacing your
o r
iginal equipment tires and installing winter tires for the winter months.
WARNING!
Falken does not recommend the use of mixing different speed
ra
tings on a vehicle. This can cause poor handling and
unpredictable steering.
WARNING!
Never use just two winter tires. It could lead to adverse handling,
lo
ss of control, which could cause serious injury or death.

CONTROLLABILITY
Controlling a vehicle when a tire failure occurs
If a tire failure occurs, you may hear a loud noise, feel a vibration,
an
d/or the vehicle may pull toward the side of the failed tire. If
possible, step on the accelerator momentarily to maintain forward
momentum and ensure vehicle control. It is most important that you
DO NOT BRAKE OR ABRUPTLY TURN THE STEERING WHEEL.
Slowly remove your foot from the accelerator and hold the steering
wheel firmly while steering to remain in your lane. Once the vehicle
has slowed and is fully under control, apply the brakes gently; safely
pull over to the shoulder and come to a stop. Inspect the tires. If one
or more looks flat or low, shows detachment or other damage, remove
tire assembly and replace it with a properly inflated spare. Bumps or
bulges may indicate detachment within the tire body and require
inspection by a qualified tire technician.
DRIVING ON ANY TIRE THAT DOES NOT HAVE THE CORRECT
I N
FLATION PRESSURE IS DANGEROUS
Any underinflated tire builds up excessive heat that may result in
su
dden tire destruction. If tires are supplied as original equipment,
refer to the tire decal on the vehicle (check vehicle and/or vehicle
Owner’s Manual for decal location) for the recommended operating
pressures. For replacement tires, the correct inflation pressure will be
provided by your tire retailer; if not, refer to the vehicle decal.
These inflation pressures must be maintained as a minimum.
Ho
wever, do not exceed the maximum pressure rating indicated on
the tire sidewall.
SELF-SUPPORTING TIRES. ZERO PRESSURE (ZP) TIRES, AND
PA
X® SYSTEM TIRES, AT LOW OR ZERO AIR PRESSURE
The handling characteristics of a vehicle with a deflated PAX® System
ti
re or Self- Supporting Zero Pressure (ZP) tire (whether front or rear)
are not the same as those of a vehicle with normally inflated tires.
Avoid high speeds and hard cornering whenever a low pressure
warning is activated.

good condition to assure its performance. Always utilize valve caps
capable of containing the tire’s air pressure, should the valve core
leak. The valve cap is the primary seal against air loss.
It is recommended that you have your tires and wheels balanced. Tires
an
d wheels which are not balanced may cause steering difficulties, a
bumpy ride, and irregular tire wear.
SPECIAL MOUNTING INSTRUCTIONS FOR PAX® SYSTEM TIRES
PAX System wheels are different from all other wheels. Never attempt
to
mount a non-PAX System tire on a PAX System wheel, or a PAX®
System tire on a non-PAX System wheel. Attempting to do so could
cause serious injury or death. All PAX System components (tire,
wheel, support ring, pressure sensor and gel) must be utilized. Never
utilize a PAX System tire and wheel without every other properly
functioning component part, correctly installed by an Authorized
PAX System retailer. The PAX System must be used on all wheel
positions.
After a low or zero pressure driving event, the PAX System tire and
wh
eel may be hot to the touch. Always allow a PAX® System tire to
cool before attempting to handle it. Failure to do so could result in
injury.
SPECIAL MOUNTING INSTRUCTIONS FOR SELF-SUPPORTING
ZE
RO PRESSURE™ (ZP) TIRES
ZP tires can be more difficult to mount than conventional tires. They
sh
ould be mounted and demounted only by a properly trained tire
professional. ZP tires can generate a tremendous amount of heat when
run at low or zero pressure. ALWAYS ALLOW A ZP TIRE TO COOL
BEFORE ATTEMPTING TO HANDLE IT. FAILURE TO DO SO
COULD RESULT IN INJURY.
MICHELIN® ZP tires are tubeless tires designed to operate in
em
ergency conditions at low or zero air pressure.
MICHELIN® SELF SUPPORTING Zero Pressure™ (ZP) TIRES AND
SP
ECIAL SYMMETRIC HUMP-MODIFIED (SH-M) WHEELS
Some MICHELIN® ZP tires can only perform with zero pressure
ca
pability when mounted on special SH-M wheels. These tires bear
the SH-M designation immediately following the ZP designation on
the sidewall of the tire. DO NOT MOUNT ZP TIRES WITH THE SH-M
DESIGNATION ON STANDARD WHEELS. IN SUCH
