TIRE MIXING
• Toyo Tires® recommends that all four tires be of the same size,
s
peed 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.
• Match tire size designations in pairs on an axle, except during the
t
emporary use of a spare tire.
• If two radial tires and two non-radial tires are used on a vehicle, put
t
he radials on the rear 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
M
anual specifies speed-rated tires, the replacement tires must have
the same or higher speed rating to maintain vehicle speed capa -
bility.
• F
ailure to follow proper procedures. For proper mounting proce -
d
ures, consult the Rubber Manufacturers Association’s publica -
tion “Care and Service of Automobile and Light Truck Tires”
(r
ef.: www.ustires.org ).
•
Exceeding the maximum bead seating pressure of 40 psi. Be
a
bsolutely certain beads are fully seated before adjusting the
inflation pressure to the level recommended for vehicle opera -
tion.
Never put flammable substances in the tire/wheel assemblies at
an
y time. Never put any 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,
co
nstructions, 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.
WARNING! (Continued)

• 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.

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.
TOYO TIRES® – LIMITED WARRANTY
237
Full-size spare tires (not temporary spares) of the same size,
construction, and speed rating may be used in a five-tire rotation
pattern.
After rotation, check the inflation pressure of all the tires. The front
an
d rear tire pressures may vary according to the vehicle
manufacturer’s specifications.
Remember to follow your vehicle Owner’s Manual for tire rotation
in
tervals. Your Limited Warranty recommends Toyo brand tires to be
rotated as follows:
• Every 3,500
miles or less for high performance (low profile) tires.
• Every 7,500 m
iles or less for standard passenger and light truck tires.

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.

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
-TRUCK
TOYO TIRES® – LIMITED WARRANTY
248
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.
