The mounting of tires and installation of the Tire Pressure Monitoring
System (TPMS) should be carried out by an authorized Pirelli dealer.
Pirelli “Seal Inside” Technology
Select Pirelli tires incorporate “Seal Inside” technology, a construction
designed to stop the loss of air from a tire in most circumstances when \
the tire is punctured by an object. The “Seal Inside” technology is
not designed or intended to be a permanent repair. Should the “Seal
Inside” technology be activated, immediately drive your vehicle to
an authorized Pirelli dealer for an inspection to determine if repair or\

replacement is needed. Go to www.us.pirelli.com for more information.
Pirelli Noise Canceling System
Select Pirelli tires are constructed with Pirelli Noise Canceling System\

(PNCS). This is a technology that reduces the tire cavity noise caused
by the vibration of the tire structure when rolling on the road surface,\

which is one of the major factors generating noise inside the vehicle.
Tire Replacement
The tires fitted to your vehicle as Original Equipment were tested and
approved by the vehicle manufacturer and the tire manufacturer and
take into account all aspects of the vehicle’s operation. Changes in
the tire size, type or construction should not be made without seeking
advice from the vehicle or tire manufacturer or an authorized Pirelli
dealer since unapproved tires on your vehicle could adversely affect
steering, handling, braking and traction. The tire information (tire size,
load index and speed rating) as found on the vehicle placard or in the \
owner’s manual should always be followed when replacing tires. It
is strongly recommended that Pirelli tires be mounted in sets of four
with the same tread type. Pirelli tires should not be mixed with other
tire brands. It is necessary to follow this procedure because different
tire constructions have different handling characteristics. Tires on
the same axle must be the same manufacturer, brand, tire size, load
index, speed rating and Pirelli part number. When changing only two
tires on a vehicle which is homogeneously fitted (four tires of the same
tire size), fit the new tires on the rear axle. This applies to all vehicles
regardless of their drive axle (Front or Rear Drive).

PIRELLI
202
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

PIRELLI
203
minimum tread depth and they may be dangerous if left in service.
Tires should be removed from service for numerous reasons,
including tread worn down to minimum depth, damage or abuse
(including, without limitation, punctures, cuts, impacts, cracks, bulges,
under inflation, overloading, etc.). For these reasons, tires, including
spares, should be inspected at least once a month and before long
trips. Inspection should occur regardless of whether the vehicle is
equipped with a tire pressure monitoring system. In addition to these
visual conditions, consumers should take note of and address any
change in performance such as increased air loss, noise or vibration or \
other factors.
The mere passage of time (age) does not cause tires to deteriorate,
but rather exposure to outside forces. The service life of a tire is a
function of service and storage conditions. For each individual tire,
this service life is determined by many factors such as temperature/
weather, storage conditions, and service conditions (e.g., load, speed,
inflation pressure, maintenance, and road hazard damage, etc.) to
which a tire is subjected throughout its life. Since service and storage
conditions vary widely, accurately predicting the service life of any
specific tire based on chronological age is not possible. There is no
scientific or technical data that establishes or identifies a minimum
or maximum service life, but the longer a tire has been in service,
the greater the chance that it will need to be replaced due to service-
related conditions.
Only use a mild soap solution to clean tires and rinse the soap off with
low pressure tap water, use of high-pressure sprayers may cause
damage. Never apply cleaners or other products to enhance sidewall
or tire appearance to avoid removal of substances which are intended
to protect the tire and reduce rubber degradation associated with the
impact of ozone and other environmental conditions.
The removal of these substances may degrade the rubber and can
lead to sidewall cracking. To remove the protective film from a Pirelli
tire with white letters, first flood the area with a stream of water from a
hose. After a minute or two the film will soften and it can be removed
with soft nylon brush if needed.

WARNING: Driving on a damaged tire is dangerous, as the tire can
suddenly fail, which can lead to an accident and serious personal
injury or death.
Tire Rotation
Pirelli recommends that you follow the tire rotation procedure as
defined in your vehicle owner’s manual. If there is no procedure
specified, Pirelli recommends tire rotation every 5,000 to 7,000 miles to
optimize your tire wear.
Tire Repair
Punctures, nail holes or cuts located in the tread area of Pirelli
tires may be repaired if the diameter does not exceed 1/4”. The
repair material used must seal the inner liner and fill the injury to be
considered a permanent repair. U.S. Tire Manufacturers Association
and industry approved repair methods include a combination of a
plug and a patch; chemical or hot vulcanizing patches, and head type
plugs; all which are applied from inside the tire. A self-vulcanizing plug
repair may be used only in conjunction with a patch repair, but not
by itself. Plugs may cause further damage to the tire, are not always
airtight and may fail. If a tire puncture exceeds 1/4” or is located \
in the
shoulder or sidewall deflection areas, the tire must be replaced. Never
resort to tubes in tubeless tires or sleeves or large thick patches, whi\
ch
can upset the balance and may result in a sudden failure at highway
speeds and high operating temperatures.
WARNING: Driving on an improperly repaired tire is dangerous,
as the tire can suddenly fail, which can lead to an accident and
serious personal injury or death.
Pirelli Prohibits the Following for Safety Reasons:1.
The use of aftermarket tire sealants in Pirelli tires to repair, even
temporarily, a puncture;
2.
The repairing of V, W, Y or Z Speed Rated tires.

PIRELLI
205
Storage
Should you need to store tires they should be stored indoors in a
cool, dry place. Tire storage areas should be cool (45° F ~ 75° F),
dry, non-dusty, and moderately well ventilated. To protect your tires
from damage related to heat, water, ozone and direct sunlight, it is
suggested you place them in opaque, waterproof containers (e.g.,
plastic trash bags). It is vital that the tires do not come in contact \
with
sources of heat and/or ozone i.e. radiators, electric generators/motors,\

hot pipes, etc., and tires should never be allowed to stand or come into\

contact with water, grease, fuels, brake fluid or any other chemicals.
If you need to transport your tires, please follow the above guidelines.\
WARNING: Driving on an improperly stored tire is dangerous,
as the tire can suddenly fail, which can lead to an accident and
serious personal injury or death.
Tubes in Tubeless Tires
Under no circumstances are tubes to be used in Pirelli tires marked
“Tubeless”. This includes tires that have been repaired. If the tire’s
pressure retention ability has been affected, so as to necessitate a
tube being installed, the tire must be replaced instead.
Tire Valves
Whenever new tires are installed on your wheels, new tire valves of the \
correct type must be installed. During your routine tire inspection, ver\
ify
that all your valves have proper valve caps. Replace as necessary,
since the valve cap is also a seal against pressure loss.
Tire Dismounting and Mounting
Tire fitting should be left to professionals who have the equipment
and training to perform the task properly and safely using U.S. Tire
Manufacturers Association procedures or the vehicle manufacturer’s
recommendations. To maximize the performance of your tires, they
must be installed following the tire sidewall markings with respect to

PIRELLI
206
direction of rotation (directional arrow) or the proper side facing outside
(Outside/Inside). Your wheels should be in good, clean condition.
Wheels should be inspected for distortion, dents, cracks, rust and
foreign matter, and be replaced as necessary. NEVER EXCEED 40
PSI WHEN SEATING BEADS. Both beads and wheels must be clean,
undamaged and well lubricated prior to bead seating.
Tire/Wheel Alignment and Balancing
Tire/Wheel alignment specifications are issued by your vehicle
manufacturer and your vehicle must be kept within the vehicle
manufacturer tolerances. You should have your alignment checked
annually or whenever you notice any irregular wear or vibrations. Tire/
Wheel alignment is important for safety, maximum performance and
mileage from your tires.
Tire/Wheel assemblies should be balanced each time a tire is mounted
to a wheel.

Temporary Spare Tire1.
If less than 50% Worn: Toyo Tires will replace, free of charge,
any Eligible Tire when the original usable tread is worn by 50% or
less, and within 5 years from the date you purchased the vehicle
new. If you cannot provide a copy of the new vehicle registration
or vehicle purchase receipt, the manufacture date of the tire, as
indicated by the tire DOT code, will be used instead to determine
if the tire is within the warranty period. Tire mounting and
balancing costs are covered by Toyo Tires. You are responsible
for taxes and all other costs, fees and expenses.
2.
If more than 50% Worn: Toyo Tires will replace any Eligible Tire
