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.
m NOTICE!
The traction grade assigned to tires is based on locked braking (straight
ahead) traction tests and does not include cornering (turning) traction.
• 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.
WARNING!
The temperature grade is established for a tire that is properly
inflated and not overloaded. Excessive speed, underinflation, or
excessive loading either separately or in combination can cause heat
buildup and possible tire failure. This can cause an accident, which
could lead to serious personal injury or death.
• DOT Quality Grades - All passenger car tires must conform to federal
requirements in addition to these grades.

2. WHAT IS NOT WARRANTED
Tires that have become unserviceable for the following reasons:
•Road hazard injuries or damages, caused to the tire by obstacles and
debris such as cuts, punctures (whether repairable or not), snags,
bruises, tears, or impact breaks.
• Improper repairs or repairs that have failed.
• Improper inflation or other maintenance abuses.
• Incorrect mounting of the tire, or tire/wheel imbalance.
• Mechanical irregularities in the vehicle such as wheel misalignment,
worn, or faulty parts.
• Accident, corrosion, vandalism, fire, or damage caused by nature.
• Tires used on vehicles in racing or special applications.
• Non-speed-rated temporary spare tires used over 50 mph (80 km/h).
• Tires worn out [2/32 inch (1.6 mm) or less of tread remaining].
• Tires that have been retreaded.
• Tires transferred from the vehicle on which they were originally
installed.
• Improper storage
3. WHAT IS WARRANTED
Tires that have become unserviceable for reasons other than stated above
will be replaced in accordance with this warranty.
If a warrantable condition is found, tires will be replaced as follows:
A) Passenger Car and Light Truck Tires (Other than Temporary Spare
Tires)
When a tire becomes unserviceable during the first 2/32 inch (1.6 mm) of
original usable tread depth or 12 months from date of vehicle purchase,
whichever comes first, it will be replaced with a comparable new
YOKOHAMA tire free of charge. During this period, tires will be
mounted and balanced without charge. Other service charges such as tire
rotation, alignment or applicable taxes are payable by the customer.

4. A tread life of up to 3,000 miles (4,800 km) can be expected dependingon road conditions and your driving habits. To conserve tire tread life,
the spare should be returned to the trunk as soon as the standard tire
can be repaired or replaced.
5. Because the YOKOHAMA high pressure spare tire was specifically designed for your car, it should not be used on any other vehicle.
6. Do not use snow chains on your YOKOHAMA high pressure spare. This could cause damage to your vehicle.
7. When the tread wear indicator appears on the tire, replace it only with the same type spare tire.
8. Check the tire’s cold inflation pressure monthly and maintain at 60 psi (4.2 kg/cm2) even when not in use. Do not inflate over 60 psi.
9. The YOKOHAMA high pressure spare tire should not be used with any other rim nor should standard tires, wheel covers, or trim rings be
used on the YOKOHAMA high pressure spare tire rim on which the
YOKOHAMA high pressure spare tire was originally installed.
IMPORTANT SAFETY INFORMATION
All tires require owner maintenance regardless of how well a tire is
constructed. Operational damages such as punctures, impact damage, cuts,
incorrect inflation, etc., may cause tire failure and subsequent personal
injury and/or property damage. Simple operational and maintenance
practices, as listed below, will reduce the chances of tire problems.
Tire Inspection
Visually inspect your tires frequently for any tire damage such as scrapes,
bulges, cuts, nails, irregular wear, etc. resulting from operation. This must
be done immediately after any known or suspected contact with an object
in the road, a pothole, road irregularity or after severe braking. Refer
these conditions to a reputable tire service center for repair or replace-
ment. Never drive on a tire if such conditions appear.
Tire Loading
Never exceed the maximum vehicle load limit listed on the vehicle
placard, tire information label or in the owners manual. Be aware of the
load carrying limits molded into the tire’s sidewall and do not exceed
those limits. Maximum load can only be carried at the maximum cold
inflation pressure indicated on the tire’s sidewall.

•Do not allow tires to spin at speeds greater than 35 mph if vehicle
becomes stuck.
• Do not stand behind a spinning tire while attempting to push a vehicle.
Speed and force can cause a tire to disintegrate and explode and may
cause property damage and/or personal injury.
YOKOHAMA TIRES — LIMITED WARRANTY
Speed Limits
Regardless of the speed capability of your tires, never exceed lawful
speeds or speeds dictated by driving conditions.
Hazards
Objects in the road that could damage your tires should be safely
avoided. These objects include: potholes, glass, metal, rocks, wood debris
and the like. Unavoidable contact should prompt a thorough tire inspec-
tion.
Air Pressure
Air pressure maintenance is critical to tire service life. Ti re pressures must
be checked frequently when tires are cold (before operation, cool to the
touch) and no less than once per month and before extended operation.
Use a tire gauge to check pressure and maintain it per the vehicle
manufacturer ’s recommendations (on vehicle placard or in owner ’s
manual). Do not reduce pressure when tire is hot and do not inflate a cold
tire higher than limits molded on the tire’s sidewall. Do not overlook
spare tire inflation pressure.
Tire Tread
Ti re s must be replaced when the depth of the tread reaches 2/32 inch
(1.6 mm). YOKOHAMA tires are manufactured with tread wear indica-
tors molded into the tire grooves which indicate tread wearout. As tires
wear down to 2/32 inch (1.6 mm), and tread depth is reduced, tire
traction is reduced during rainfall and road conditions. Visual
tire inspection therefore becomes more crucial as the tires wear out.
Hard Braking
Yo u must inspect your tires after any hard braking situations or after tires
have slid on the pavement. This can cause a flat spot or other damage to
the tread of the tire.
