WARNING!
•Failure to install tires with adequate load capacity will result in tire
fatigue and sudden tire failure. This could lead to loss of vehicle
control, possibly resulting in personal injury or death.
• Certain vehicle performance parameters, including ride comfort
and handling, may be affected by substitute tire sizes. In some
cases, particularly for SUVs and light trucks, a failure to follow the
vehicle manufacturer ’s recommendations for tire replacement
could adversely affect the safe handling of the vehicle, possibly
resulting in a loss of vehicle control leading to personal injury or
death.
The following procedures concerning replacement tires must be fol-
lowed:
• Confirm that the load-carrying capacity is greater than or equal to the
loadcarrying capacity of the OE tire size at the pressure indicated on
the vehicle Tire Information Placard.
• Carefully note any differences between recommendations for front and
rear axle positions regarding the tire size and/ or inflation pressure.
• The speed rating must be equal to or greater than what is specified by
the vehicle manufacturer if the speed capability of the vehicle is to be
maintained.
• Tires should be mounted on approved wheel widths. If changing tire
sizes, check to make sure the wheel has adequate load and inflation
pressure capacity.
• Body and chassis clearance must be checked on the vehicle’s front and
rear axles.
In addition to the above, light truck tire replacements should take into
consideration the following:
• Proper spacing between dual tires is necessary for optimum tire
performance. If chains are used, particular care must be taken to assure
adequate clearance between loaded tires to avoid damage from the
chains. The allowable outside diameter difference between a tire and
its dual mate is 1/4” (6.4 mm) for light truck tires.

CONSIDERATIONS IN PLUS SIZING
Always refer to and follow the vehicle manufacturer ’s replacement tire
recommendations. In some cases, a vehicle manufacturer may specifically
advise against the application of replacement tires that are not of the
original size or type.
TIRE AND WHEEL MATCHING AND MOUNTING
WARNING!
Any attempt to mount a tire on a wheel with a different diameter
will result in an explosion of the tire/wheel assembly that could
cause severe personal injury or death.
Prior to mounting any tire, always check the wheel identification
stamp to verify the correct wheel diameter. Always check the tire
size molded onto the sidewall.
Never exceed 40 psi when seating the tire beads onto the wheel.
Always stand well clear of any tire mounting operation. This is
especially important when the service operator inflates the tire. If
the tire has been improperly mounted, it could burst with explosive
force causing serious personal injury or death.
A new valve stem must be installed on the wheel each time a worn
out passenger or light truck tire is replaced.
Removing and replacing tires on wheels can be dangerous.
Attempting to mount tires with improper tools or procedures could
result in a tire explosion, causing serious personal injury or death.
This is a job for your authorized Toyo Tires dealer or other qualified
tire service location only.
Serious personal injury or death can result from:
•Failure to select the proper tire and wheel. The tire must match the
width and diameter requirements of the wheel. When mounting
truck type radial tires use only wheels approved for radial tires.
• Failure to inspect both the tire and wheel. The wheel must be free
of cracks, dents, chips, and rust. The tire must be free of bead
damage, cuts, and punctures.
• Failure to follow proper procedures. For proper mounting proce-
dures, consult the Rubber Manufacturers Association’s publication
“Care and Service of Automobile and Light Truck Tires” (ref.:
www.rma.org).

WARNING!(Continued)
•Exceeding the maximum bead seating pressure of 40 psi. Be
absolutely certain beads are fully seated before adjusting the
inflation pressure to the level recommended for vehicle operation.
Never put flammable substances in the tire/wheel assemblies at any
time. Never put any flammable substance into a tire/wheel assembly
and attempt to ignite it in order to seat the beads.
TIRE MIXING
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.
• 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.
• Match tire size designations in pairs on an axle, except during the
temporary use of a spare tire.
• If two radial tires and two non-radial tires are used on a vehicle, put
the 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
Manual specifies speed-rated tires, the replacement tires must have the
same or higher speed rating to maintain vehicle speed capability.
• 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
TOYO TIRES – LIMITED WARRANTY
236
Page 238 of 270
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
the lowerspeed- 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)
VEHICLES
If no instructions for tire mixing appear in the vehicle Owner ’s Manual,
follow these guidelines:
• Do not mix tire sizes. All four tires must be marked with the same tire
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.
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.
• If winter/snow tires are applied to the front 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 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.

STUDDED WINTER/SNOW TIRES
•Studded winter/snow tires have higher traction qualities under most
winter weather conditions.
• If studded winter/snow tires are installed on the front 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!
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.
m NOTICE!
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.
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.

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 and
rear tire pressures may vary according to the vehicle manufacturer ’s
specifications.
Remember to follow your vehicle Owner ’s Manual for tire rotation
intervals. 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 miles or less for standard passenger and light truck tires.

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 different
tire and construction types mixed on the vehicle.
• Some tires cannot be rotated in the manner described. Such tires
include 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
rear 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 for
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
rotation pattern. Consult the vehicle Owner ’s Manual.
• Do not include temporary spare tires in the rotation pattern. However,
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 manufac-
turer ’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 to
the vehicle manufacturer ’s recommendation or the inflation pressure
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 tires
must remain on the rear axle. Consult your 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.
WARNING!
No tire, regardless of its design or speed rating, has an unlimited
capacity 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.
Toyo Tires does not endorse the operation of any vehicle in an unsafe or
unlawful manner. Obey all local speed limits.
Tire speed ratings do not imply that a vehicle can be safely driven at the
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!
High-speed driving with underinflated or overloaded tires may
result 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
speed 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 symbols
of all the tires.
• Follow the vehicle manufacturer ’s recommendations, if any, concern-
ing the use of speed-rated tires.
To avoid reducing the speed capability of the vehicle, replace a speed-
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.

ZR Over 149 mph (240 km/h)**
(Y) Over 186 mph (300 km/h)**
* Any tire with a speed capability above 149 mph (240 km/h) can, at the
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 capa-
bility (P245/40ZR18 speed capability is greater than 149 mph
[240 km/h]). If a service description is included with the size description,
the speed capability is limited by the speed symbol in the service
description (i.e., 235/45ZR17 97W = maximum speed 168 mph
[270 km/h]).
** Although no upper limit speed is specified, the indicated tires
nonetheless 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.
mNOTICE!
Tire speed symbols do not imply that vehicles can be safely driven 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.
