5. DOT Street Legal Competition Tires
P Zero Trofeo and P Zero Corsa tire lines use special tire construction
an
d compounds to achieve their distinctive performance in dry
conditions. As a result of that, their performance in cold temperatures,
heavy rain or standing water will be decreased. Use extreme caution
and drive slowly on wet roads.
The minimum tread depth will be reached earlier than normal road
ti
res, resulting in reduced tread life.
6. Winter Tires
The standard Pirelli tires may be effective in light snow conditions.
Ho
wever, for winter use, you may wish to install winter tires. During
winter use, Pirelli strongly recommends the fitment of four winter
tires. Please check your vehicle owner’s manual concerning winter tire
size recommendation. If the winter tires have a lower speed rating
than the original equipment tires, vehicle handling may be affected,
and the vehicle maximum speed must be reduced to the winter tire
speed rating.
Pirelli requires
that studded tires be installed on all four positions.
Installing studded tires only on the drive positions of any vehicle,
including a front wheel drive vehicle, may cause adverse handling
characteristics.
7. Run Flat Tires
Always refer to the vehicle owners’ manual with respect to specific
sa
fety and operating information relating to the vehicle. Damaged
Run Flat tires or Run Flat tires that have experienced a loss of pressure
should immediately be replaced with another Run Flat tire of identical
size and Service Description (Load Index and Speed Symbol).
Run Flat tires have been developed based on the specifications of the
ve
hicles on which they are mounted. Accordingly, Run Flat tires
should only be mounted on vehicles specifically manufactured to
accommodate Run Flat tires.
Run Flat tires must be mounted in conjunction with a functional Tire
Pr
essure Monitoring System (TPMS).
The mounting of tires and installation of the TPMS should be carried
ou
t by a specialized dealer.

8. Tire Replacement
The tires fitted to your vehicle as original equipment were tested and
ap
proved 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 symbol) 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
w i
th 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
(f
our 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).
On all wheel drive or four wheel drive vehicles the tires must always
be
replaced in sets of four.
When replacing tires on light truck vehicles, you should always follow
th
e 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:
22
5/45R17) 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 be sure of the exact interchangeability to
maintain proper vehicle dynamics.
Please be aware that it is important that, before fitting the suggested
ti
res, the fitment is allowed by the technical specifications of the
vehicle, the vehicle manufacturer and the relevant homologations.
Pirelli Tire does not express any view as to the compatibility of the
wheel/tire combination with the technical specifications for the
chassis and vehicle.
PIRELLI TIRES
208
TO MAINTAIN PROPER 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 making plus size fitments, you should consult with the dealer
re
garding any suspension or braking system modifications which
may be recommended for the vehicle.
9. Tire Inspection
As a minimum, tires (including the spare tire) should be examined
an
d 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 tire dealer and
replaced if necessary. Pirelli tires have treadwear indicators in the
tread grooves, which show up when the tread has worn to 2/32”
remaining. At this point, your tires must be replaced because they are
illegal and dangerous.
The mere passage of time (age) does not cause tires to deteriorate, but
ra
ther exposure to outside forces. Such outside forces can include, but
are not limited to: road hazards, punctures, improper repairs,
misalignment, under inflated operation, over inflated operation,
excessive heat caused by over deflected operation, excessive exposure
to ozone, improper storage conditions, etc. Tire companies can only
have an impact on a few of these exposures. Tire companies add
antiozinants and anti-oxidants (anti-degradation compounds) to
minimize degradation. Pirelli believes that since there is no way to
accurately predict what outside forces a tire will be exposed to there is
no scientifically supportable age limit that can be set for tires.
To avoid cosmetic damage, use a mild soap solution to clean sidewalls
a n
d rinse off with low-pressure tap water. Never apply cleaners or
dressings to enhance sidewall appearance to avoid removal of
antioxidants, which are intended to prevent ozone degradation. The
removal of anti-oxidants may degrade the rubber and can lead to
sidewall cracking. Use of high-pressure sprayers may cause sidewall
damage.
WARNING!
Driving on a damaged tire is dangerous, as the tire can suddenly
fa
il, which can lead to an accident and serious personal injury or
death.

Toyo Tires 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 diam-
eter.
• The repair will be the first repair performed on that tire. (Only one
r
epair per tire is permitted in order to maintain a limited speed
rating.)
• The tire must have more than 2/32” (1.6
mm) of tread remaining.
Toyo Tires speed-rated passenger tires that have been properly
re
paired qualify for reduced speed ratings as follows:
The maximum speed of a vehicle is limited by the lowest-speed- rated
ti
re on the car.
PROPER SELECTION OF TIRES
When tires need to be replaced, do not guess what tire is right for your
v e
hicle. First look at the vehicle Owner’s Manual or the Tire
Information Placard. They tell you the size of the tires that were on the
vehicle as original equipment.
Replacement tires for any vehicle must be of a size, load range, and
lo
ad capacity (by inflation) that is capable of supporting the same load
as the vehicle’s Original Equipment (OE) installed tires. Avoid
installing used tires on a vehicle. There is no way to determine what
road hazards or abuse a previously owned tire may have incurred.
ORIGINAL SPEED RATING AFTER PUNCTURE REPAIR

CAUTION!
A tire’s speed rating is void if the tire has been retreaded,
da
maged, abused, or otherwise altered from its original condition.
Thereafter, it should be treated as a non-speed-rated tire. In
addition, retreaded passenger and light truck tires are not
warranted by Toyo Tires for any reason. Toyo Tires speed ratings
are voided for retreaded tires.
TOYO TIRES® – LIMITED WARRANTY

The following procedures concerning replacement tires must be
followed:
• Confirm that the load-carrying capacity is greater than or equal to
t
he loadcarying capacity of the OE tire size at the pressure indicated
on the vehicle Tire Information Placard.
• Carefully note any differences between recommendations for front
a
nd rear axle positions regarding the tire size and/or inflation pres-
sure.
• The speed rating must be equal to or greater than what is specified
b
y the vehicle manufacturer if the speed capability of the vehicle is
to be maintained.
• Tires should be mounted on approved wheel widths. If changing
t
ire sizes, check to make sure the wheel has adequate load and infla -
tion pressure capacity.
• Body and chassis clearance must be checked on the vehicle’s front
a
nd rear axles.
In addition to the above, light truck tire replacements should take into
co
nsideration the following:
• Proper spacing between dual tires is necessary for optimum tire
p
erformance. If chains are used, particular care must be taken to
assure adequate clearance between loaded tires to avoid damage
from the chains. The allowable outside diameter difference between
a tire and its dual mate is 1/4 inch (6.4 mm) for light truck tires.
WARNING!
• Failure to install tires with adequate load capacity will result in
t
ire fatigue and sudden tire failure. This could lead to loss of
vehicle control, possibly resulting in personal injury or death.
• Certain vehicle performance parameters, including ride comfort
a
nd handling, may be affected by substitute tire sizes. In some
cases, particularly for SUVs and light trucks, a failure to follow
the vehicle manufacturer’s recommendations for tire replace -
ment could adversely affect the safe handling of the vehicle,
po
ssibly resulting in a loss of vehicle control leading to personal
injury or death.

CONSIDERATIONS IN PLUS SIZING
Always refer to and follow the vehicle manufacturer’s replacement
ti
re recommendations. In some cases, a vehicle manufacturer may
specifically advise against the application of replacement tires that are
not of the original size or type.
TIRE AND WHEEL MATCHING AND MOUNTING
WARNING!
Any attempt to mount a tire on a wheel with a different diameter
wi
ll 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
st
amp 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
es
pecially 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
wo
rn 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
co
uld result in a tire explosion, causing serious personal injury or
death. This is a job for your authorized Toyo Tires 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
t
he 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
f
ree of cracks, dents, chips, and rust. The tire must be free of bead
damage, cuts, and punctures.

231
TIRE MIXING
• Toyo Tires® recommends that all four tires be of the same size,
s
peed rating, and construction (radial or non-radial). In some cases
the vehicle manufacturer may require different sized tires for the
front or rear axles. Never mix P-metric or European Metric
passenger tires with LT-metric tires on the same vehicle.
• Match tire size designations in pairs on an axle, except during the
t
emporary use of a spare tire.
• If two radial tires and two non-radial tires are used on a vehicle, put
t
he radials on the rear axle. If radial and non-radial tires are used on
a vehicle equipped with dual rear tires, the radial tires may be used
on either axle.
SPEED-RATED TIRE
• If the vehicle Tire Information Placard and/or the vehicle Owner’s
M
anual specifies speed-rated tires, the replacement tires must have
the same or higher speed rating to maintain vehicle speed capa -
bility.
• F
ailure to follow proper procedures. For proper mounting proce -
d
ures, consult the Rubber Manufacturers Association’s publica -
tion “Care and Service of Automobile and Light Truck Tires”
(r
ef.: www.ustires.org ).
•
Exceeding the maximum bead seating pressure of 40 psi. Be
a
bsolutely certain beads are fully seated before adjusting the
inflation pressure to the level recommended for vehicle opera -
tion.
Never put flammable substances in the tire/wheel assemblies at
an
y time. Never put any flammable substance into a tire/wheel
assembly and attempt to ignite it in order to seat the beads.
CAUTION!
Driving your vehicle with an improper mix of tire sizes,
co
nstructions, and speed ratings can be dangerous. Your car’s
handling characteristics can be adversely affected. You could have
an accident resulting in serious personal injury or death. Consult
your vehicle Owner’s Manual or an authorized Toyo Tires dealer
for proper tire replacement.
