TIRE MIXING
• Toyo Tires® recommends that all four tires be of the same size, speed rating, and construction (radial or non-radial). In some cases the vehicle manufacturer may
require different sized tires for the front or rear axles. Never mix P-metric or European
Metric passenger tires with LT-metric tires on the same vehicle.
• M atch tire size designations in pairs on an axle, except during the temporary use of a
s
pare tire.
• I f two radial tires and two non-radial tires are used on a vehicle, put the radials on the
r
ear axle. If radial and non-radial tires are used on a vehicle equipped with dual rear
tires, the radial tires may be used on either axle.
SPEED-RATED TIRE
• If the vehicle Tire Information Placard and/or the vehicle Owner’s Manual specifies speed-rated tires, the replacement tires must have the same or higher speed rating to
maintain vehicle speed capability.
• I f a replacement tire has a lower speed capability than that specified by the vehicle
m
anufacturer, 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.
• I f tires with different speed ratings are used, it is recommended that the lower speed-
r
ated tires always be placed on the front axle. This is to prevent a potential oversteer
condition.
• E
xceeding the maximum bead seating pressure of 40 psi. Be absolutely certain
b
eads are fully seated before adjusting the inflation pressure to the level recom -
mended for vehicle operation.
Never put flammable substances in the tire/wheel assemblies at any time. Never put
a n
y flammable substance into a tire/wheel assembly and attempt to ignite it in order
to seat the beads.
CAUTION!
Driving your vehicle with an improper mix of tire sizes, constructions, and speed
ratings can be dangerous. Your car’s handling characteristics can be adversely
affected. You could have an accident resulting in serious personal injury or death.
Consult your vehicle Owner’s Manual or an authorized Toyo Tires® dealer for proper
tire replacement.

FOUR-WHEEL DRIVE (4WD) AND ALL-WHEEL DRIVE (AWD) VEHICLES
If no instructions for tire mixing appear in the vehicle Owner’s Manual, follow these
guidelines:
• D o not mix tire sizes. All four tires must be marked with the same tire size, unless
o
therwise specified by the vehicle manufacturer. This also applies to winter/snow
tires.
• D o not mix tread pattern types such as all-terrain and all- season.
STUDLESS WINTER/SNOW TIRES
• It is always preferable to apply winter/snow tires to all wheel positions, including dual
tires, to maintain vehicle mobility and control.
• I f 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.
STUDDED WINTER/SNOW TIRES
• Studded winter/snow tires have higher traction qualities under most winter weather conditions.
• I f 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.
WARNING!
Unless winter/snow tires on the rear axle have comparable traction 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.
WARNING!
Installing only two studded winter/snow tires on the front axle of any 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.

REPLACING TWO TIRES
• When a pair of replacement tires is selected in the same size and construction 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.
• W hen two new tires have been installed onto the rear axle positions, they are to be
k
ept 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 suspension systems, gear ratios, transmission, and tire treadwear.
• I f single tire replacement is unavoidable, it is recommended that the single new tire
b
e 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 considerations for safety and getting the maximum mileage from your tires. You need to check how your tires are
wearing at least once a month.
• Y our vehicle may be out of alignment if your tires are wearing unevenly, such as when
t
he inside shoulder of the tire is wearing faster than the rest of the tread. This condi -
tion not only shortens the life of your tires, it adversely affects the handling character -
istics of your vehicle, which could be dangerous. If your tires show irregular wear, have
y o
ur vehicle’s alignment checked immediately.
CAUTION!
In some cases, the vehicle manufacturer may specifically advise against 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.

TIRE WEAR – VISUAL CHECK
If you experience a blowout or a sudden tire failure, the following information should be
helpful:
• W hen the tire failure occurs, you may hear a loud noise, or feel a vibration, and/or the
v
ehicle may pull toward the side of the failed tire. Do not abruptly brake or turn.
• M aintain steady pressure on the accelerator pedal.
•
Hold the steering wheel firmly and steer to maintain your lane position.
•
Find a safe place to pull off the road and allow the vehicle to gradually decelerate.
A
pply light braking as required to stop safely.
WARNING!
Beware of Sudden Tire Vibration. A tire failure may lead to loss of vehicle control,
which could cause serious personal injury or death. Many tire failures are preceded by
vibration, bumps, bulges, or irregular wear. If while driving your vehicle you experience
any unusual vibration, pull, ride disturbance, or noise and/or you suspect possible
vehicle or tire damage, do not continue to drive. Pull over to a safe area as soon as
possible and inspect the tires for signs of bulges, blisters, or separations. Seek
roadside assistance or change the damaged tire with your spare tire.

• Gradually pull over to the shoulder and come to a stop. Look for a damaged tire on your vehicle.
• S eek roadside assistance or change the damaged tire with your spare tire.
•
Have all of your tires and the vehicle thoroughly inspected by a tire professional.
TIRE ROTATION
The purpose for rotating tires is to achieve more uniform wear for all tires 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 vehicle Owner’s
M a
nual for rotation advice.
Full-size spare tires (not temporary spares) of the same size, construction, and speed
r a
ting may be used in a five-tire rotation pattern.
After rotation, check the inflation pressure of all the tires. The front and rear tire
p r
essures may vary according to the vehicle manufacturer’s specifications.
TOYO TIRES® – LIMITED WARRANTY
181
Remember to follow your vehicle Owner’s Manual for tire rotation intervals. Your Limited
Warranty recommends Toyo Tires® brand tires to be rotated as follows:
• E very 3,500
miles or less for high performance (low profile) tires.
• E very 7,500
miles or less for standard passenger and light truck tires.
More frequent rotation or a thorough vehicle inspection may be necessary if, upon
i n
spection, irregular or erratic treadwear is beginning to appear.
It is important to remember the following:
• These tire rotation recommendations do not take into account different tire and c
onstruction types mixed on the vehicle.
• S ome tires cannot be rotated in the manner described. Such tires include unidirec -
t
ional tires. Unidirectional tread patterns must be rotated front-to-rear only so that the
d i
rection of revolution does not change.
• S ome vehicles are designed with different tire sizes on the front and rear axles.
N
ormally, such combinations will not allow rotation. Prior to rotating, consult the
vehicle Owner’s Manual.
• F or vehicles with dual rear wheels, see the vehicle Owner’s Manual for the vehicle
m
anufacturer’s procedures. If your vehicle Owner’s Manual is not available, please
contact the vehicle manufacturer.
• S ome vehicles are equipped with wheels that limit the choice of rotation pattern.
C
onsult the vehicle Owner’s Manual.
• D o not include temporary spare tires in the rotation pattern. However, if your spare tire
i
s 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 avail -
able, to use the appropriate rotation pattern shown, inserting the spare in the right
r e
ar position. Place the tire that would have gone to the right rear in the spare tire
storage position as the new spare.
• I mportant! After rotation, adjust the pressure of the individual tires to the vehicle
m
anufacturer’s recommendation or the inflation pressure recommended by Toyo
Tires® for an optional fitment according to the tire’s new location on the vehicle.
• D o not mix speed-rated tires on the same axle. Higher speed-rated tires must remain
o
n the rear axle. Consult an authorized Toyo Tires® dealer.
TIRE SPEED RATING
All Toyo Tires® passenger, light truck, and truck tires have a maximum speed rating
based on size and type. Tires must never be operated in excess of their rated speed limit!
Consult your tire dealer or contact Toyo Tires® at 1-800-442-8696 (Pacific Time) or
1-888-444-8696 (Eastern Time) if you are not sure about the maximum speed rating of
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
a n
d 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 wear, and replace -
m
ent should be considered in order to maintain effectiveness in heavy snow condi-
tions.
• T ire speed rating – When lower-speed-rated winter tires replace higher-speed-rated
t
ouring and high performance all-season radial tires, do not exceed the lower-rated
speed.
• F ollow recommendations in the vehicle Owner’s Manual for winter tires, studs, and
c
hains.
• C onsult your tire dealer, the US Tire Manufacturers Association (USTMA) website
h
ttps://www.ustires.org/ , or your state’s Department of Transportation (DOT) for infor -
mation regarding regulatory and seasonal restrictions for stud usage.
• A lso see the “Tire Mixing” section in this manual for more details.
•
Toyo Tires® recommends that snow tires be installed in matched sets of four.
WARNING!
Spinning a tire to remove a vehicle stuck in mud, snow, or wet grass 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
mph (55 km/h) can reach a speed capable of disintegrating a tire with
e x
plosive 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
d i
rectly behind 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 paved surfaces.
Failure to allow for adequate braking distance could result in serious personal injury or
death.

• When you replace the temporary tire, replace it only with the same type of tire.
• A full-size spare tire in your vehicle is intended for use as a spare when needed. Please
s
ee the “Tire Rotation” section for the proper procedures for including the same size
construction and speed-rated tire (for LT tires of the same size, type, and load rating)
in the rotation pattern. Do not rotate a temporary spare tire.
TIRE STORAGE
Tires should be stored indoors in a cool dry place where water cannot collect 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.
COMPETITION TIRE STORAGE
The rubber compounds used in these tires have unique properties that, when compared
to other tires, can cause them to lose some of their flexibility when used or handled in
conditions below 15° F (-9° C). This loss in flexibility can lead to potential cracking and
other damage to the tire. To minimize the chances of this happening, you are advised to
follow these instructions:
1. Do not move or operate the car with these tires in conditions below 15° F (-9° C).
2
. A void moving these tires in conditions below 15° F (-9° C).
3
. B efore mounting and dismounting, store these tires for at least 24 hours in a
t
emperature-controlled environment of 68° F (20° C) or warmer.
WARNING!
• Check inflation pressure before using your spare tire. Failure to have 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 used with any other
w
heel, 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.
• D o not operate your vehicle with more than one temporary spare in use (this does
n
ot apply to a full size spare), and only operate it at limited speeds and distances as
indicated on the sidewall of the tire.
• T he “T” Type temporary spare tire may lower ground clearance when used. Avoid
d
riving 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.
