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 SPEED RATING
All Toyo Tires® passenger, light truck, and truck tires have a
ma
ximum 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.
Toyo Tires® does not endorse the operation of any vehicle in an
u n
safe or unlawful manner. Obey all local speed limits.
Tire speed ratings do not imply that a vehicle can be safely driven at
th
e speed for which the tire is rated. Speed ratings are based on
laboratory tests and relate to performance on the road, but are not
applicable if tires are underinflated, overloaded, worn out, damaged,
or altered.
WARNING!
No tire, regardless of its design or speed rating, has an unlimited
ca
pacity for speed. Exceeding the tire’s speed capability could
cause overheating and sudden tire failure, possibly leading to loss
of vehicle control and serious personal injury or death.
WARNING!
High-speed driving with underinflated or overloaded tires may
re
sult in immediate tire failure, possibly leading to loss of vehicle
control, which could cause an accident, including 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.

COMPETITION TIRE STORAGE
The rubber compounds used in these tires have unique properties
th
at, 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
da
mage 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
1
5° F (-9° C).
2. Avoid moving these tires in conditions below 15° F (-9° C).
3
. Before mounting and dismounting, store these tires for at least 24 hours
i
n a temperature- controlled environment of 68° F (20° C) or warmer.
4. Remove these tires from the vehicle and deflate to half the normal
a
ir-pressure during prolonged periods of non-use or storage.
Always inspect tires for signs of cracking and never use tires that
ha
ve cracked.
SPECIAL ADVICE FOR LIGHT TRUCKS
Never exceed the speed limit as indicated by the speed symbol on the
ti
re’s sidewall. See the chart and explanation of speed ratings in this
manual.
If you do not know the speed rating of your Toyo brand tire, contact
yo
ur Toyo Tires® dealer or Toyo Tire U.S.A. Corp. for current
information.
WARNING!
Improper storage can damage your tires in ways that may not be
vi
sible and could lead to serious personal injury or death.

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).
REPLACEMENT TIRES FOR LIGHT TRUCKS – P-METRIC VS.
LT

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 utility
vehicle, or a trailer.
When a P-metric or metric tire is installed on a light truck (SUV,
p i
ckup, minivan), the load rating is reduced by dividing by 1.1. (This
load reduction factor is prescribed by Federal Motor Vehicle Safety
Standards (FMVSS) and is based on the expectation that
passenger-type tires may experience more severe loading and usage
conditions when applied to light trucks.) For example, 305/50R20 has
a maximum load capacity of 3086 lbs. If this tire is fitted to a light
truck, the actual allowable load for the tire is 2805 lbs. (3086 lbs.
divided by 1.1).
Consult the load and inflation charts that can be found at
www.toyotires.com
. Contact Toyo Tires® Technical Service with any tire
replacement questions: 1-
800-442-8696 (Pacific Time) or
1-888-444-8696 (Eastern Time).
WARNING!
• P-metric and LT-metric tires are not necessarily interchangeable.
P
-metric and LT-metric tires follow completely different Load/
Inflation tables and are designed to carry different loads at
different pressures.
• LT-metric tires carry their load at higher inflation pressures and
d
o not always have adequate load capacity to replace P-metric
tires of the same size.
• After reducing a P-metric tire’s load rating by dividing by 1.1 for
f
itment on a Light Truck, the P-metric tire may not offer suffi -
cient load capacity to replace an LT-metric tire of the same size.
• Contact your Toyo Tires dealer or Toyo Tires Technical Service
f
or help determining how to choose a proper replacement size.
• Driving with underinflated or overloaded tires may result in
i
mmediate tire failure, which can cause an accident and could
lead to serious personal injury or death.

VEHICLES WITH MODIFIED SUSPENSION
USEFUL TIRE INFORMATION
There is a lot of useful information molded into the sidewall of a tire.
I t
shows the name of the tire, its size, if it is tubeless or tube type, the
maximum load and maximum inflation, and important safety
warnings. The sidewall markings on passenger and light truck tires
are slightly different.
WARNING!
Large-diameter tires and modified suspensions that increase
g r
ound clearance will alter vehicle handling.
• The vehicle may become more likely to roll over.
•
Braking distances may increase.
•
Slower speeds may be required to maintain control.
D
rive with extreme caution until you become familiar with how
yo
ur vehicle handles. Always wear your seat belt.
Some modifications may be illegal in your state. Consult your
Ow
ner’s Manual, the instructions for this product, and state law
before modifying your vehicle.

tions of their use and may vary due to driving habits, service prac-
tices, differences in road characteristics, and climate.
• Traction - The traction grades from highest to lowest are AA, A, B,
a
nd C, and they represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified government
test surfaces of asphalt and concrete.
• Temperature - The temperature grades are A (the highest), B, and C,
r
epresenting the tire’s resistance to the generation of heat and its
ability to dissipate heat when tested under controlled conditions on
a specified indoor laboratory test wheel. Sustained high tempera -
tures can cause the materials of the tire to degenerate and reduce tire
li
fe, and excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance that all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard
No. 139. Grades B and A represent higher levels of performance on
the laboratory test wheel than the minimum required by law.
• D OT Quality Grades - All passenger car tires must conform to
f
ederal requirements in addition to these grades. CAUTION!
The traction grade assigned to tires is based on locked braking
( s
traight ahead) traction tests and does not include cornering
(turning) traction.
WARNING!
The temperature grade is established for a tire that is properly
in
flated and not overloaded. Excessive speed, underinflation, or
excessive loading either separately or in combination can cause
heat buildup and possible tire failure. This can cause an accident,
which could lead to serious personal injury or death.
