• 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.

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.

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 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.

EXPLANATION OF TIRE SPEED SYMBOLS
A speed rating is designated by a letter that indicates the maximum
s p
eed capability of a tire. The speed rating of a tire is based on
standards for reaching and sustaining a specified speed, and is
determined via laboratory tests that simulate road performance at
various speeds.
Tires may be marked with one of these speed symbols: M, N, P, Q, R,
S,
T, U, H, V, W, Y, or (Y) to identify the particular tire’s speed rating.
Additionally, the letter Z may appear in the size designation.
When purchasing or replacing speed-rated tires, make sure to:
• Use the ranking in the following chart to compare the speed
s
ymbols of all the tires.
• Follow the vehicle manufacturer’s recommendations, if any,
c
oncerning the use of speed-rated tires.
To avoid reducing the speed capability of the vehicle, replace a
sp
eed-rated tire only with another tire having at least the same or
higher speed rating. Remember, the “top speed” of the “lowest rated”
tire on the car cannot be exceeded without risk of tire failure.

The letter symbols and corresponding design speeds are:
* Any tire with a speed capability above 149 mph (240 km/h) can, at
t h
e tire manufacturer’s option, include a “Z” in the size designation
(e.g., 245/40ZR18). If the load index and the speed symbol are not
included, the tire manufacturer must be consulted for the maximum
speed capability (P245/40ZR18 speed capability is greater than
149 mph [240 km/h]). If a service description is included with the size
de
scription, the speed capability is limited by the speed symbol in the
service description (i.e., 235/45ZR17 97W = maximum speed 168 mph
[2
70 km/h]).
** Although no upper limit speed is specified, the indicated tires
no
netheless have limited rated speed capability. Call 1-800-442-8696
(Pacific Time) or 1-888-444-8696 (Eastern Time) for a referral for more
technical information.
Speed-Rated Symbol Speed Category
M Up to 81 mph (130 km/h)
N Up to 87 mph (140 km/h)
P Up to 93 mph (150 km/h)
Q Up to 99 mph (160 km/h)
R Up to 106 mph (170 km/h)
S Up to 112 mph (180 km/h)
T Up to 118 mph (190 km/h)
U Up to 124 mph (200 km/h)
H Up to 130 mph (210 km/h)

CAUTION!
Tire speed symbols do not imply that vehicles can be safely
dr
iven at the maximum speed for which the tire is rated,
particularly under adverse road and weather conditions, or if the
vehicle has unusual characteristics. Never operate a vehicle in an
unsafe or unlawful manner.

plus a mountain/snowflake symbol . Even the best all-season tires
will not provide acceptable levels of traction if you drive too fast in
snow or ice conditions and if you do not allow more stopping
distance on icy roads compared to dry road surfaces. Your ability to
safely maneuver your vehicle in snow or ice conditions is consider -
ably reduced if your tires are too worn to provide adequate road grip.
SAFE USE OF TEMPORARY SPARE TIRES
• T he temporary spare tire is designed for temporary use only. It must
n
ot be used continuously as a standard tire. The temporary spare
tire should be returned to the trunk as soon as it is convenient to
have your standard tire repaired or replaced.
• The temporary spare tire should not be used for speeds exceeding
5
0 mph.
• Never use chains on temporary spare tires, because it could cause
d
amage to your vehicle.
• When you replace the temporary tire, replace it only with the same
t
ype of tire.
• A full-size spare tire in your vehicle is intended for use as a spare
w
hen needed. Please see 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.
WARNING!
The spare tire your car is equipped with may be of a different size
an
d construction from the other tires on your vehicle. When using
any temporary type spare tire, be sure to follow the vehicle
manufacturer’s instructions. Failure to observe recommended
precautions could lead to erratic vehicle behavior and/or tire
damage, possibly resulting in an accident and serious personal
injury or death.
