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.

WARNING!(Continued)
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.
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.
NITTO TIRE
296

Full-size spare tires (not temporary spares) of the same size, construction,
and speed rating may be used in a five-tire rotation pattern.
After rotation, check the inflation pressure of all the tires. The front and
rear tire pressures may vary according to the vehicle manufacturer ’s
specifications.
Remember to follow your vehicle Owner ’s Manual for tire rotation
intervals. Your Limited Warranty recommends Nitto brand tires to be
rotated as follows:
•Every 3,500 miles or less for high performance (low profile) tires.
•
Every 7,500 miles or less for standard passenger and light truck tires.
NITTO TIRE
297

More frequent rotation or a thorough vehicle inspection may be necessary
if, upon inspection, irregular or erratic treadwear is beginning to appear.
It is important to remember the following:
•These tire rotation recommendations do not take into account different
tire and construction types mixed on the vehicle.
•Some tires cannot be rotated in the manner described. Such tires
include unidirectional tires. Unidirectional tread patterns must be
rotated front-to-rear only so that the direction of revolution does not
change.
•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 manufac-
turer ’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 Nitto 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 Nitto dealer.
TIRE SPEED RATING
All Nitto passenger and light 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 Nitto at

•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
characteristics 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).
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 Nitto brand tire, contact your
Nitto dealer or Nitto Tire U.S.A. Inc. 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
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.
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 Nitto dealer or Nitto 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
