NITTO TIRE
171
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.
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
NITTO TIRE
172
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 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
Technical Services at (888) 529-8200 Pacific Time if you are not sure
about the maximum speed rating of your tires.
Nitto 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.

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 utilit\
y
vehicle, or a trailer.

Pirelli Run Flat tires are manufactured with technology that allows
limited low inflation operation in the event of sudden loss of pressure.
As a result, in addition to the standard warranty coverage, Pirelli
provides road hazard coverage on both Pirelli Original Equipment Tires

For Example:
Load Index Number: a numeric code which indicates the maximum
load carrying capacity of a tire at the maximum cold inflation pressure.
Speed Symbol: an alphabetical code which indicates the maximum
speed at which the tire can carry a load corresponding to its Load
Index when properly inflated. These two items together are known as
the “Service Description”.
Speed Symbol Chart
*For tires having a maximum speed capability above 149 mph, a “ZR”
may appear in the size designation; above 186 mph, a “ZR” must
appear in the size designation, and a Service Description, including the\
“Y” speed symbol, must be included in brackets.

Tire Categories
ALL SEASON TIRES (All Weather Tires): Tires that are designed to
perform in a variety of road conditions in All Seasons of the year. An
All Season tire will carry “M+S”, “M&S”, or “M/S” desi\
gnation on the
sidewall. All Season tires may carry a treadwear warranty depending
on the product line.
SUMMER TIRES: Summer tires offer superior handling, grip and
cornering ability compared to standard tires under certain conditions.
Some lines may carry a treadwear warranty.
WINTER TIRES (Snow Tires): A winter tire is a tire with a tread design
and compound made specifically for snow and ice conditions and
is identified by M&S, M+S or M/S markings on the sidewalls. Tires
designed for use in severe snow conditions are further identified with a
pictograph of a mountain with a snowflake on the sidewalls and must
meet specific snow performance test requirements. Pirelli Winter tires
do not carry a treadwear warranty.
The information provided above is an overview of tire types. Tread
patterns and rubber compounds vary among the seasonal tire types
and provide varying performance characteristics and limitations.
Summer performance tires are different than winter and All Season
types. To determine which Pirelli lines carry a treadwear warranty,
please refer to the “Treadwear Coverage” sections in this document.
Pressure Recommendations
Recommended tire inflation pressures for your vehicle can be found
either on your vehicle’s tire placard or in your owner’s manual. Correct
pressures are related to load, speed and vehicle handling and are
vital for even braking, maximum traction and good tire life. Under no
circumstances should your tires’ cold inflation pressure be less than
PIRELLI
199
that indicated on your vehicle’s tire placard or in your owner’s manual
or higher than the maximum cold inflation pressure molded on to the
tire’s sidewall. Under inflation causes excessive flexing, deterioration of
the tire and rapid wear of the tread edges. Over inflation results in an
uncomfortable ride, a reduced area of tire contact with the road surface\
(i.e., smaller tire footprint), higher susceptibility to impact damage and
rapid wear on the tread center. Whether inflated by air or nitrogen,
regular inflation pressure maintenance remains critical and necessary.
Use of nitrogen alone is not a replacement for regular inflation
pressure maintenance.
WARNING: Driving on tires with improper inflation pressure is
dangerous. These situations can cause a tire failure, including
tread/belt separation, even at a later date, which could lead to an
accident and serious personal injury or death.
Inflation pressure must be checked at least once a month and before
long trips, and should be checked only when the tire is cold or before i\
t
has been driven. Driving even a short distance causes tires to heat up
and the air pressure to increase. Never reduce or “bleed” air from\
hot
tires since your tires will then be underinflated when they cool down.
Always use a reliable pressure gauge.
UHP Summer Tires
The special tread compounds formulated for Ultra High Performance
(UHP) summer tires are optimized for maximum dry and wet
performance in warm temperatures. The compounds in these tires will
have decreased performance, such as lateral and braking traction, at
temperatures below 45° F or when driving on snow or ice. In addition,\
they can lose flexibility and may develop random surface cracks
at very cold temperatures; therefore extra care should be used in
handling tires. All Season or winter tires should be installed for use at
temperatures below 45° F, UHP summer tires are not recommended
for lower temperature conditions.

On all wheel drive or four wheel drive vehicles the tires must always
be replaced in sets of four. When replacing tires, you should always
follow the vehicle manufacturer’s recommendations. Passenger and
light truck tires are not interchangeable, due to differences in their
pressures and load carrying capacity.
P-Metric and Euro-Metric Interchangeability: Euro-Metric (Example:
225/45R17) tires have a load index which is equal to or greater than
that of the same size P-Metric (Example: P225/45R17) tire. Therefore,
they have the same or higher load carrying capacity at the maximum
rated inflation pressure. Always check with your tire dealer or Pirelli
Tire Consumer Affairs to check interchangeability to maintain proper
vehicle dynamics.
Please be aware that it is important, before fitting the suggested tires,
to confirm that the fitment is allowed by the technical specifications of
the vehicle, the vehicle manufacturer and the relevant homologations.
Pirelli does not express any view as to the compatibility of the wheel/
tire combination with the technical specifications for the chassis
and vehicle.
TO MAINTAIN VEHICLE DYNAMICS AND LOAD CARRYING
CAPACITY, REPLACEMENT TIRES MUST ALWAYS HAVE A LOAD
INDEX AND SPEED SYMBOL EQUAL TO OR GREATER THAN
THOSE FITTED AS ORIGINAL EQUIPMENT.
When installing plus size fitments, you should consult with the dealer
regarding any suspension or braking system modifications which may
be recommended for the vehicle.
Tire Inspection
As a minimum, tires should be examined and air pressure checked
monthly and always prior to long trips. They should also be examined
if you strike any unusual object on the road. Tires showing bulges,
cracks, cuts, penetrations or uneven wear must be dismounted and
examined by an authorized Pirelli dealer and replaced if necessary.
Pirelli tires have treadwear indicators in the tread grooves, which
clearly show when the tread has worn to 2/32” remaining. At this point,
your tires must be replaced because they do not meet the federal
