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.

TIRE SPINNING
WARNING!
Spinning a tire to remove a vehicle stuck in mud, snow, or wet grass
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 per hour
(55 km/h) can reach a speed capable of disintegrating a tire 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
behind the spinning tire. Do not spin if a drive wheel is off the
ground.
TOWING OR USE OF SLIDE-IN TRUCK CAMPERS
If you are towing a trailer or using a slide-in truck camper, refer to your
vehicle Owner ’s Manual.
WINTER (SNOW) TIRES
Winter driving presents special challenges for vehicle
handling. The use of winter tires, studs, and chains, while
improving traction performance in snow and ice, requires
additional caution and care with regard to braking, corner-
ing, and speed. It is important to drive with care not only
on snow and ice, but on dry and wet roads as well.
WARNING!
Studded tires may require longer braking distances on dry or wet
paved surfaces. Failure to allow for adequate braking distance could
result in serious personal injury or death.
•Traction is considerably reduced as snow tires approach 50% tread
wear, and replacement should be considered in order to maintain
effectiveness in heavy snow conditions.
•Tire speed rating – When lower-speed-rated winter tires replace
higher-speedrated touring and high performance all-season radial
tires, do not exceed the lower-rated speed.
TOYO TIRES – LIMITED WARRANTY

These tires are marked with the “M&S” designation 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 considerably reduced if your tires
are too worn to provide adequate road grip.
SAFE USE OF TEMPORARY SPARE TIRES
WARNING!
The spare tire your car is equipped with may be of a different size
and 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.
•The temporary spare tire is designed for temporary use only. It must
not 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
50 mph.
•Never use chains on temporary spare tires, because it could cause
damage to your vehicle.
•When you replace the temporary tire, replace it only with the same
type of tire.
•A full-size spare tire in your vehicle is intended for use as a spare when
needed. Please see the “Tire Rotation” section for the proper proce-
dures 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!
•Check inflation pressure before using your spare tire. Failure to
have 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 used
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 characteris-
tics 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 in
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
when 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.
TIRE STORAGE
Tires should be stored indoors in a cool dry place where water cannot
collect 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.
COMPETITION TIRE STORAGE
The rubber compounds used in these tires have unique properties that,
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 damage 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
15° F (-9° C).
TOYO TIRES – LIMITED WARRANTY
250
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 in a temperature-controlled environment of 68° F (20° C) or
warmer.
4. Remove these tires from the vehicle and deflate to half the normal
air-pressure during prolonged periods of non-use or storage.
Always inspect tires for signs of cracking and never use tires that have
cracked.
WARNING!
Improper storage can damage your tires in ways that may not be
visible and could lead to serious personal injury or death.
SPECIAL ADVICE FOR LIGHT TRUCKS
Never exceed the speed limit as indicated by the speed symbol on the
tire’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 your
Toyo Tires dealer or Toyo Tire U.S.A. Corp. for current information.
TIRES DESIGNATED AS “LT” WITH NO SPEED RATING INDI-
CATED 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
TOYO TIRES – LIMITED WARRANTY
251
speeds in excess of 65 mph may be required, then the following
adjustments or recommendations should be followed:
•At speeds from 66 mph through 75 mph, cold inflation pressure must
be increased 10 psi above the recommended pressures for the load
being carried.
•Do not exceed the maximum inflation pressure of the wheel (all wheels
have maximum allowable inflation pressures).
REPLACEMENT TIRES FOR LIGHT TRUCKS – P-METRIC VS .
LT-TRUCK
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.
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.
(Continued)
TOYO TIRES – LIMITED WARRANTY
252
WARNING!(Continued)
•LT-metric tires carry their load at higher inflation pressures and do
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
fitment on a Light Truck, the P-metric tire may not offer sufficient
load capacity to replace an LT-metric tire of the same size.
•Contact your Toyo Tires dealer or Toyo Tires Technical Service for
help determining how to choose a proper replacement size.
•Driving with underinflated or overloaded tires may result in
immediate tire failure, which can cause an accident and could lead
to serious personal injury or death.
When a P-metric or metric tire is installed on a light truck (SUV, pickup,
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).

VEHICLES WITH MODIFIED SUSPENSION
WARNING!
ROLLOVER HAZARD
Large-diameter tires and modified suspensions that increase ground
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.
Drive with extreme caution until you become familiar with how
your vehicle handles. Always wear your seat belt.
Some modifications may be illegal in your state. Consult your
Owner ’s Manual, the instructions for this product, and state law
before modifying your vehicle.
USEFUL TIRE INFORMATION
There is a lot of useful information molded into the sidewall of a tire. It
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.
