The following procedures concerning replacement tires must be
followed:
• Confirm that the load-carrying capacity is greater than or equal to
t
he loadcarying capacity of the OE tire size at the pressure indicated
on the vehicle Tire Information Placard.
• Carefully note any differences between recommendations for front
a
nd rear axle positions regarding the tire size and/or inflation pres-
sure.
• The speed rating must be equal to or greater than what is specified
b
y the vehicle manufacturer if the speed capability of the vehicle is
to be maintained.
• Tires should be mounted on approved wheel widths. If changing
t
ire sizes, check to make sure the wheel has adequate load and infla -
tion pressure capacity.
• Body and chassis clearance must be checked on the vehicle’s front
a
nd rear axles.
In addition to the above, light truck tire replacements should take into
co
nsideration the following:
• Proper spacing between dual tires is necessary for optimum tire
p
erformance. 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 inch (6.4 mm) for light truck tires.
WARNING!
• Failure to install tires with adequate load capacity will result in
t
ire 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
a
nd 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 replace -
ment could adversely affect the safe handling of the vehicle,
po
ssibly resulting in a loss of vehicle control leading to personal
injury or death.

CONSIDERATIONS IN PLUS SIZING
Always refer to and follow the vehicle manufacturer’s replacement
ti
re 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
wi
ll 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
st
amp 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
es
pecially 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
wo
rn 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
co
uld 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
t
he 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
f
ree of cracks, dents, chips, and rust. The tire must be free of bead
damage, cuts, and punctures.

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.

• 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.

TIRE WEAR – VISUAL CHECK
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.

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 SPINNING
TOWING OR USE OF SLIDE-IN TRUCK CAMPERS
If you are towing a trailer or using a slide-in truck camper, refer to
y o
ur vehicle Owner’s Manual.
WINTER (SNOW) TIRES Winter driving presents special challenges for vehicle
handling. The use of winter tires, studs, and chains,
wh
ile improving traction performance in snow and 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
w
ear, and replacement should be considered in order to maintain
effectiveness in heavy snow conditions.
• Tire speed rating – When lower-speed-rated winter tires replace
h
igher-speed-rated touring and high performance all-season radial
tires, do not exceed the lower-rated speed.
WARNING!
Spinning a tire to remove a vehicle stuck in mud, snow, or wet
gr
ass 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 miles
pe
r hour (55 km/h) can reach a speed capable of disintegrating a
ti
re with explosive 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 directly
be
hind 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
pa
ved surfaces. Failure to allow for adequate braking distance
could result in serious personal injury or death.
