• If a replacement tire has a lower speed capability than that specified
by the vehicle manufacturer, the vehicle’s speed must be restricted
to that of the replacement tire. Vehicle handling could also be
affected. Consult the vehicle Owner’s Manual or tire manufacturer
for recommendations.
• If tires with different speed ratings are used, it is recommended that
t
he lower speed- rated tires always be placed on the front axle. This
is to prevent a potential oversteer condition.
FOUR-WHEEL DRIVE (4WD) AND ALL-WHEEL DRIVE (AWD)
VE
HICLES
If no instructions for tire mixing appear in the vehicle Owner’s
Ma
nual, follow these guidelines:
• Do not mix tire sizes. All four tires must be marked with the same
t
ire size, unless otherwise specified by the vehicle manufacturer.
This also applies to winter/snow tires.
• Do not mix tread pattern types such as all-terrain and all- season.
S
TUDLESS WINTER/SNOW TIRES
• It is always preferable to apply winter/snow tires to all wheel posi -
t
ions, including dual tires, to maintain vehicle mobility and control.
• If winter/snow tires are applied to the f
ront axle of any vehicle,
winter/snow tires must also be installed on the
rear axle. DO NOT
apply winter/snow tires only to the front axle. This applies to all
passenger and light truck vehicles, including front-wheel- drive,
4WD, and AWD vehicles.
• If winter/snow tires are installed on the rear axle of any vehicle, it is
recommended (but not required) that they also be installed on the
front axle.
WARNING!
Unless winter/snow tires on the rear axle have comparable
tr
action qualities to the tires on the front axle, the vehicle may
experience adverse handling characteristics. This may result in
loss of vehicle control, which can lead to serious personal injury
or death.

STUDDED WINTER/SNOW TIRES
• Studded winter/snow tires have higher traction qualities under
m
ost winter weather conditions.
• If studded winter/snow tires are installed on the f
ront axle of any
vehicle, studded winter/snow tires must also be installed on the
rear axle. DO NOT apply studded winter/snow tires only to the
front axle.
• If studded winter/snow tires are installed on the rear axle of any
vehicle, it is strongly recommended that they should also be
installed on the
front axle. Only if studded winter/snow tires are
installed on all wheel positions of a vehicle will optimum handling
characteristics be achieved.
REPLACING TWO TIRES
• When a pair of replacement tires is selected in the same size and
c
onstruction as those on the vehicle, the two newer tires must be
installed on the rear axle and must be of equal or higher speed rating
than the front tires. Generally, new tires with deeper tread will
provide better grip and evacuate water more effectively, which is
important as a driver approaches hydroplaning situations. Placing
greater traction on the rear axle on wet surfaces is necessary to
prevent a possible oversteer condition and loss of vehicle stability.
WARNING!
Installing only two studded winter/snow tires on the front axle of
an
y vehicle (including front-wheel-drive vehicles) without
studded winter/snow tires on the rear axle can cause adverse
vehicle handling characteristics. This can result in a loss of
vehicle control, which could cause serious personal injury or
death.
CAUTION!
In some cases, the vehicle manufacturer may specifically advise
ag
ainst replacing fewer than all four tires. Always check and
follow the recommendations in the vehicle Owner’s Manual. For
4WD and AWD vehicles, even small differences in outside
diameter may cause drivetrain damage or mechanical
malfunction.

• When two new tires have been installed onto the rear axle positions,
they are to be kept on the rear but rotated from side to side. This is
recommended after installing two new tires to the rear position, or
if you discover significant tread depth differences between the front
and rear positions during rotation intervals.
REPLACING ONE TIRE
• Replacing a single tire on a vehicle can have an adverse effect on
s
uspension systems, gear ratios, transmission, and tire treadwear.
• If single tire replacement is unavoidable, it is recommended that the
s
ingle new tire be paired with the tire that has the deepest tread and
both be placed on the rear axle. Placing greater traction on the rear
axle on wet surfaces is necessary to prevent a possible oversteer
condition and loss of vehicle stability.
WHEEL ALIGNMENT AND BALANCING
• Proper wheel alignment and balance are very important consider -
a
tions for safety and getting the maximum mileage from your tires.
Yo
u need to check how your tires are wearing at least once a month.
• Your vehicle may be out of alignment if your tires are wearing
u
nevenly, such as when the inside shoulder of the tire is wearing
faster than the rest of the tread. This condition not only shortens the
life of your tires, it adversely affects the handling characteristics of
your vehicle, which could be dangerous. If your tires show irregular
wear, have your vehicle’s alignment checked immediately.

If you experience a blowout or a sudden tire failure, the following
information should be helpful:
• When the tire failure occurs, you may hear a loud noise, or feel a
v
ibration, and/or the vehicle may pull toward the side of the failed
tire. Do not abruptly brake or turn.
• Maintain steady pressure on the accelerator pedal.
•
Hold the steering wheel firmly and steer to maintain your lane posi -
t
ion.
• Find a safe place to pull off the road and allow the vehicle to gradu -
a
lly decelerate. Apply light braking as required to stop safely.
• Gradually pull over to the shoulder and come to a stop. Look for a
d
amaged tire on your vehicle.
• Seek roadside assistance or change the damaged tire with your
s
pare tire.
• Have all of your tires and the vehicle thoroughly inspected by a tire
p
rofessional.
TIRE ROTATION
The purpose for rotating tires is to achieve more uniform wear for all
ti
res on a vehicle. Your tires should be thoroughly examined on a lift
by a tire dealer for any abnormalities. If tires show uneven treadwear,
ask the service person to check and/or correct any vehicle wheel
alignment or other mechanical problem before rotation.
The following rotation patterns are acceptable. Please refer to your
ve
hicle Owner’s Manual for rotation advice.

238
More frequent rotation or a thorough vehicle inspection may be
necessary if, upon inspection, irregular or erratic treadwear is
beginning to appear.
It is important to remember the following:
• These tire rotation recommendations do not take into account
d
ifferent tire and construction types mixed on the vehicle.
• Some tires cannot be rotated in the manner described. Such tires
i
nclude unidirectional tires. Unidirectional tread patterns must be
rotated front-to-rear only so that the direction of revolution does not
change.
• Some vehicles are designed with different tire sizes on the front and
r
ear axles. Normally, such combinations will not allow rotation.
Prior to rotating, consult the vehicle Owner’s Manual.
• For vehicles with dual rear wheels, see the vehicle Owner’s Manual
f
or the vehicle manufacturer’s procedures. If your vehicle Owner’s
Manual is not available, please contact the vehicle manufacturer.
• Some vehicles are equipped with wheels that limit the choice of
r
otation pattern. Consult the vehicle Owner’s Manual.
• Do not include temporary spare tires in the rotation pattern.
H
owever, if your spare tire is the same size and type as a road tire
(for LT tires of the same size, type, and load rating), it should be
included in the tire rotation process. The proper procedure is to use
the vehicle manufacturer’s recommended tire rotation procedures,
or if not available, to use the appropriate rotation pattern shown,
inserting the spare in the right rear position. Place the tire that
would have gone to the right rear in the spare tire storage position
as the new spare.
• Important! After rotation, adjust the pressure of the individual tires
t
o the vehicle manufacturer’s recommendation or the inflation pres-
sure recommended by Toyo Tires for an optional fitment according
to
the tire’s new location on the vehicle.
• Do not mix speed-rated tires on the same axle. Higher speed-rated
t
ires must remain on the rear axle. Consult an authorized Toyo Tires
dealer.

TIRE SPINNING
TOWING OR USE OF SLIDE-IN TRUCK CAMPERS
If you are towing a trailer or using a slide-in truck camper, refer to
y o
ur vehicle Owner’s Manual.
WINTER (SNOW) TIRES Winter driving presents special challenges for vehicle
handling. The use of winter tires, studs, and chains,
wh
ile 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.
• T raction is considerably reduced as snow tires approach 50% tread
w
ear, and replacement should be considered in order to maintain
effectiveness in heavy snow conditions.
• Tire speed rating – When lower-speed-rated winter tires replace
h
igher-speed-rated touring and high performance all-season radial
tires, do not exceed the lower-rated speed.
WARNING!
Spinning a tire to remove a vehicle stuck in mud, snow, or wet
gr
ass can be dangerous. This could cause serious personal injury
or death to a bystander or passenger and extensive vehicle
damage. A tire spinning at a speedometer reading above 35 miles
pe
r hour (55 km/h) can reach a speed capable of disintegrating a
ti
re with explosive force within a matter of seconds. Under some
conditions, a tire may be spinning at twice the speed shown on
the speedometer. Never spin a tire above a speedometer reading
of 35 mph (55 km/h). Never allow anyone to stand near or directly
be
hind the spinning tire. Do not spin if a drive wheel is off the
ground.
WARNING!
Studded tires may require longer braking distances on dry or wet
pa
ved surfaces. Failure to allow for adequate braking distance
could result in serious personal injury or death.

TIRE STORAGE
Tires should be stored indoors in a cool dry place where water cannot
co
llect inside the tires. The tires should be placed away from harmful
ozone-producing electric generators and motors and sources of heat
such as hot pipes. Storage surfaces should be clean and free of grease,
gasoline, or other substances, which can deteriorate the rubber.
WARNING!
• Check inflation pressure before using your spare tire. Failure to
h
ave proper inflation pressure when using your spare tire may
cause loss of vehicle control, which could result in serious
personal injury or death. Maintain spare tire inflation pressures
based on the vehicle Owner’s Manual or the Tire Information
Placard.
• “T” Type high-pressure temporary spare tires should not be
u
sed with any other wheel, nor should standard tires, snow tires,
wheel covers, or trim rings be used on the high-pressure spare
tire wheel. If you fail to follow this warning, your vehicle’s
handling characteristics can be seriously affected. You could
have an accident resulting in serious personal injury or death.
Consult your vehicle Owner’s Manual for the proper use of your
“temporary use” spare tire.
• Do not operate your vehicle with more than one temporary spare
i
n use (this does not apply to a full size spare), and only operate
it at limited speeds and distances as indicated on the sidewall of
the tire.
• The “T” Type temporary spare tire may lower ground clearance
w
hen used. Avoid driving over large obstacles and other road
hazards. Check your vehicle Owner’s Manual for other special
clearance precautions when using the “T” Type temporary spare
tire provided in your vehicle.

TIRES DESIGNATED AS “LT” WITH NO SPEED RATING
INDICATED ON THE SIDEWALL
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
fo
llowing adjustments or recommendations should be followed:
• At speeds from 66
mph through 75 mph, cold inflation pressure
mu
st be increased 10 psi above the recommended pressures for the
load being carried.
• Do not exceed the maximum inflation pressure of the wheel (all
w
heels have maximum allowable inflation pressures).
