Important factors in tire care are:•
Proper inflation pressure
•
Proper vehicle loading
•
Proper vehicle maintenance
•
Regular inspection
•
Good driving habits
Refer to your vehicle Owner’s Manual for additional tire safety and
service advice.
TIRE PRESSURE BASICS
The combined effect of losing 1 psi per month over several months
along with a 1 psi decrease for every 10°F temperature drop could
add up to a severe “run low” condition; consequently, it is important to
check your tires’ inflation pressure at least once per month. Inflation
pressure enables a tire to support its load; therefore, proper inflation
is critical.
HOW TO DETERMINE PROPER TIRE INFLATION PRESSURE
It is impossible to determine whether tires are properly inflated
just by looking at them.

IDENTIFYING DAMAGED TIRES•
If your tire strikes a road hazard at any speed, internal tire damage
could result, which may lead to sudden tire failure and loss of
vehicle control. Tire failure may even occur miles after the initial
impact. Impact damage from such hazards may not be visible on
the outside of the tire. Have your Toyo Tires dealer dismount the
tire and inspect it for damage. A tire may not have visible signs of
damage on the tire surface or the interior.
•
If the impact was sufficient to bend the wheel flange, internal
tire damage may have occurred, compromising the safety and
integrity of the tire. Such impact damage may result in a sudden
tire failure many weeks or months later. Tire replacement is highly
recommended as a safety precaution.
•
Indications of impact damage include, but are not limited to, a
bubble or a blister on the outside of the tire.
•
Have your dealer inspect your tires if you see anything unusual
or if cuts, cracks, splitting, or bruises in the tread and sidewall
areas are visible. Bumps or bulges may indicate a serious and
dangerous separation within the tire body. Have your tire inspected
by a qualified tire service person. It may be necessary to have the
tire removed from the wheel for a complete inspection.
•
Inspect your tires for adequate tread depth. When the tire is worn
to the built-in indicators at 2/32” (1.6 mm) or less tread groove
depth, the tire is worn out and must be replaced. Never drive on
tires to the point that the tire cord or the fabric is exposed.
•
Inspect your tires for uneven wear. Wear on one side of the
tread or flat spots in the tread may indicate alignment or other
problems with the tires or the vehicle. Consult your authorized
Toyo Tires dealer.

Toyo Tires speed-rated passenger car tires may be repaired and
returned to service under the following conditions:•
Proper repair materials and procedures have been used.
•
The damage or puncture is not larger than 1/4” (6.4 mm)
in diameter.
•
The repair will be the first repair performed on that tire. (Only
one repair per tire is permitted in order to maintain a limited
speed rating.)
•
The tire must have more than 2/32” (1.6 mm) of tread remaining.
Toyo Tires speed-rated passenger tires that have been properly
repaired qualify for reduced speed ratings as follows:
The maximum speed of a vehicle is limited by the lowest-speed-rated
tire on the car.
PROPER SELECTION OF TIRES
When tires need to be replaced, don’t guess what tire is right for your
vehicle. First look at the vehicle Owner’s Manual or the Tire Information
Placard. They tell you the size of the tires that were on the vehicle as
original equipment.

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
vibration, 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 position.
•
Find a safe place to pull off the road and allow the vehicle to
gradually decelerate. Apply light braking as required to stop safely.
•
Gradually pull over to the shoulder and come to a stop. Look for a
damaged tire on your vehicle.
•
Seek roadside assistance or change the damaged tire with your
spare tire.
•
Have all of your tires and the vehicle thoroughly inspected by a
tire professional.
TIRE ROTATION
The purpose for rotating tires is to achieve more uniform wear for all
tires 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
vehicle Owner’s Manual for rotation advice.

TOYO TIRE
231
• 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 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
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 contac\
t
Toyo Tires Technical Services at (800) 442-8696 (Pacific Time) or
(888) 444-8696 (Eastern Time) if you are not sure about the maximum
speed rating of your 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.
The letter symbols and corresponding design speeds are:
* 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 manufactu\
rer 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 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 Toyo Tires Technical Services (800) 442-8696
(Pacific Time) or (888) 444-8696 (Eastern Time) for a referral for more technical
information.

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).

UNIFORM TIRE QUALITY GRADING (UTQG)
The Uniform Tire Quality Grading (“UTQG”) standards are intended to
assist you in making an informed choice in your purchase of passenger
car tires by providing information indicating relative performance in th\
e
areas of treadwear, wet stopping traction, and temperature resistance.
All passenger car tires must conform to federal safety requirements in
addition to these grades.•
Treadwear - The treadwear grade is a comparative rating based
on the wear rate of the tire tested under controlled conditions on
a specified government test track. For example, a tire graded
200 would wear twice as long on the government course as a
tire graded 100. It is wrong to link treadwear grades with your
projected tire mileage. The relative performance of the tires
depends upon the actual conditions of their use and may vary
due to driving habits, service practices, differences in road
characteristics, and climate.
•
Traction - The traction grades from highest to lowest are AA, A, B,
and C, and they represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified government
test surfaces of asphalt and concrete.
• Temperature - The temperature grades are A (the highest), B, and
C, representing the tire’s resistance to the generation of heat and
its ability to dissipate heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sustained high
temperatures can cause the materials of the tire to degenerate and
reduce tire life, and excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of performance that all
passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 139. Grades B and A represent higher levels
of performance on the laboratory test wheel than the minimum
required by law.
