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. Tire 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
Tires 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 winter road conditions. Visual tire
inspection therefore becomes more crucial as the tires wear out.
Hard Braking
You 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.
Spinning
•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.

Theprorated cost of a replacement tireis determined as follows:
[(Original usable tread worn) ÷ (Original usable tread)] x (Actual current
dealer selling price).
Acomparable Nitto brand tireis the same tire, or a tire of the same basic

CONSEQUENTIAL DAMAGES(e.g., loss of time, loss of use of vehicle,
towing charges, road services, cost of rental car, inconveniences, etc.).
Some states do not allow the exclusion or limitation of incidental or
consequential damages, so the above exclusions may not apply to you.
The terms of this Limited Warranty may not be changed by anyone,

TIRE WEAR, INSPECTION AND REPLACEMENT
The shallow grooves and race compound used in this drag tire are
designed to optimize dry traction. You should expect these tires to have
a much shorter tread life, and to operate for considerably fewer miles,
than ordinary passenger tires. You should check the condition, including
tread depth, of your tires regularly and promptly replace them before the
tread reaches the wear bars. These tires should be inspected after each use
at a track or for competition purposes. Regular inspection becomes
particularly important the longer a tire has been in service. Please see the
“Identifying Damaged Tires” and “Worn Out Tire” sections for additional
information regarding tire inspection and identifying damaged tires.
NO MILEAGE WARRANTY
These tires are not guaranteed to last a specified number of miles.

IMPORTANT SAFETY INFORMATION
This manual is not intended to provide proper training or service
procedures for tire mounting, dismounting, balancing, rotation, or
repair. Please leave these tasks to qualified tire service professionals.
mNOTICE!
Nitto brand tires are designed and built with great care. Any tire, no matter
how well constructed, can fail as a result of punctures, impact damage,
underinflation/overloading or other conditions resulting from use. Tire
failures may create a risk of property damage or personal injury. To obtain the
highest possible performance, tires must be maintained properly.
Remember, you are ultimately responsible for the tires installed on your
vehicle.
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.

VEHICLES EQUIPPED WITH TIRE PRESSURE MONITORING
SYSTEMS (TPMS)
Even if your vehicle is equipped with a tire pressure
monitoring system, you should check your tire pres-
sure at least once per month when the tires are cold
(for example, after being parked overnight). Tire pres-
sure warning systems are not a substitute for regular
tire pressure maintenance.
WARNING!
If your vehicle is equipped with TPMS, read the vehicle Owner ’s
Manual regarding its operation. Some TPMS systems do not alert you
until the tires are significantly underinflated, which could result in
permanent tire damage and possible sudden tire failure. In the event
that your TPMS malfunction indicator lamp is displayed, you should
immediately pull over to a safe parking area and check your tires.
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 Nitto 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.

Nitto 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.

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 Nitto 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).
•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.
