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.

10. Tire Rotation
Pirelli recommends that you follow the tire rotation procedure as
de
fined in your vehicle owner’s manual. If there is no procedure, PTI
recommends tire rotation every 8,000 to 11,000 kilometers to optimize
your tire wear.
11. Tire Repair
Punctures, nail holes or cuts located in the tread area of Pirelli radial
ti
res may be repaired if the diameter does not exceed six mm. The
repair material used must seal the inner liner and fill the injury to be
considered a permanent repair. Tire and Rubber Association of
Canada and industry approved repair methods include a combination
of plug and patch; chemical or hot vulcanizing patches, and head type
plugs, all 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, they are not always
airtight and the plug may fail. If a tire puncture exceeds six mm 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, which can upset the balance and may result in a sudden
failure at highway speeds and high operating temperatures.
PIRELLI TIRE DOES NOT ENDORSE:
• T he use of tire sealants in Pirelli tires to repair, even temporarily, a
p
uncture
• The repairing of V, W, Y or Z Speed Rated tires
•
The repairing of Run Flat tires
WARNING!
Driving on an improperly repaired tire is dangerous, as the tire
ca
n suddenly fail, which can lead to an accident and serious
personal injury or death.

TIRE SAFETY AND MAINTENANCE INFORMATION
IMPORTANT SAFETY INFORMATION
This manual is not intended to provide proper training or service
pr
ocedures for tire mounting, dismounting, balancing, rotation, or
repair. Please leave these tasks to qualified tire service professionals.
Inflation pressure can decrease by one psi for every 10°F temperature
d r

op Important factors in tire care are:
• Proper inflation pressure
•
Proper vehicle loading
•
Proper vehicle maintenance
•
Regular inspection
•
Good driving habits
R
efer to your vehicle Owner’s Manual for additional tire safety and
se
rvice advice.
WARNING!
• Toyo Tires® are designed and built with great care. Any tire, no
m
atter 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
o
n your vehicle.

CAUTION!
The inflation pressure shown on the sidewall of the tire is not the
in
tended inflation pressure for the vehicle. Always refer to the
vehicle’s Tire Information Placard.
WARNING!
Driving on tires with insufficient inflation pressure is dangerous
be
cause it will cause your tires to overheat. This can cause sudden
tire failure, which may result in loss of vehicle control and lead to
serious personal injury or death.

RECOMMENDATIONS FOR SAFE TIRE INFLATION
• If you must inflate your tires when they are hot, add four pounds
p
er square inch (4 psi) (28 kPa) above the recommended inflation
pressure specification. Recheck the inflation pressure when the tires
are cold and adjust to the recommended inflation pressure shown
on the vehicle’s Tire Information Placard.
• Never release air or nitrogen from a hot tire in order to reach the
r
ecommended cold tire pressure. Normal driving causes tires to run
hotter and inflation pressure to increase. If you release pressure
when your tires are hot, you may dangerously underinflate your
tires. If your tires lose more than one pound per square inch (1 psi)
per month, the tire, the valve, or the wheel may be damaged.
Consult an authorized Toyo Tires dealer for an inspection.
• Over-inflation can cause the tire to be more susceptible to impact
d
amage.
• Over-inflation or underinflation may adversely affect vehicle
h
andling.
• Remember to check your spare tire. Consult your vehicle Owner’s
M
anual for the correct inflation pressure and use of a “temporary
use” spare tire. The inflation pressure specified for a spare tire is
typically different from that specified for your regular tires.
• Use valve caps to keep valve cores clean and clear of debris and to
h
elp guard against air leakage.
WARNING!
Never inflate a tire unless it is secured to the vehicle or a tire
mo
unting machine. Inflating an unsecured tire is dangerous. If
the tire bursts, it could be propelled into the air with explosive
force and cause serious personal injury or death.

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 pressure
at
least once per month when the tires are cold for
example, after being parked overnight. Tire pressure
warning systems are not a substitute for regular tire
pressure maintenance.
IDENTIFYING DAMAGED TIRES
• I f your tire strikes a road hazard at any speed, internal tire damage
c
ould 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 Toyo Tires® 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
d
amage 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 recom -
mended as a safety precaution.
• Indications of impact damage include, but are not limited to, a
b
ubble or a blister on the outside of the tire.
• Have your dealer inspect your tires if you see anything unusual or
i
f 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 qual -
ified tire service person. It may be necessary to have the tire
re
moved from the wheel for a complete inspection.
WARNING!
If your vehicle is equipped with TPMS, read the vehicle Owner’s
Ma
nual 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.

• Inspect your tires for adequate tread depth. When the tire is worn to
the built-in indicators at 2/32” (1.6 mm) or less tread groove depth,
th

e tire is worn out and must be replaced. Never drive on tires to the
point that the tire cord or the fabric is exposed.
• Inspect your tires for uneven wear. Wear on one side of the tread or
f
lat spots in the tread may indicate alignment or other problems
with the tires or the vehicle. Consult an authorized Toyo Tires®
dealer.
IDENTIFYING DAMAGED WHEELS
Periodically check to see if any of the following symptoms exist, in
w h

ich case the wheel must be replaced:
• If the flange is bent.
•
If welds or rivets are leaking.
•
If the stud holes are elongated and not round. (Improper lug nut
t
ightening could cause this.)
• If there are cracks in the wheel.
W

ORN OUT TIRES
Tires must be replaced when tread is worn to 2/32” (1.6 mm).
Tr

eadwear indicators on Toyo Tires® treads show the 2/32” depth
(1.6 mm). Most states require that tires be replaced when the tread
de

pth is worn to 2/32” (1.6 mm). Tires may lose sufficient wet and
sn

ow traction before reaching 2/32” (1.6 mm) of wear. Many wet
we

ather accidents result from skidding on worn out tires.
Excessively worn tires are more susceptible to penetrations. Consider
re
placing your tires earlier if you drive in snow or wet conditions.
WARNING!
Never drive on a tire if there is any evidence of damage. Driving
on
a damaged tire is dangerous. A damaged tire could suddenly
fail, which may result in loss of vehicle control and lead to serious
personal injury or death. Do not attempt to dismount, mount, or
repair a tire yourself. See your Toyo Tires dealer immediately if
you detect damage.

Any retail tire dealer will be glad to measure your tire’s tread depth
for you. Toyo Tires® recommends that tires be replaced in matched
sets of four.
TIRE REPAIRS
If any tire has sustained a puncture, have the tire dismounted and
in
spected internally by an authorized Toyo Tires® dealer for possible
damage that may have occurred. Only specially trained personnel
using the proper tools and procedures should repair tires.
• N ever repair a tire with 2/32” (1.6
mm) or less tread remaining. At
th
is tread depth, the tire is worn out and must be replaced.

• Never repair a tire with a puncture larger than 1/4” (6.4
mm) in diam-
eter. Such tires cannot be properly repaired and must be replaced.

• Repairs of all tires (radial and non-radial) must be of the plug and
i
nside patch type. Using plugs alone on any type of tire is not a safe
repair.
WARNING!
Continued operation of your vehicle with excessively worn tires
ma
y lead to loss of vehicle control in adverse weather conditions,
tire failure, and serious personal injury or death.
WARNING!
• Before having your tire repaired, tell your authorized Toyo Tires
d
ealer if you have used an aerosol puncture sealant to inflate/
seal the tire. Aerosol puncture sealants could contain a highly
flammable, explosive gas.
• Driving on an improperly repaired tire is dangerous. An
i
mproper repair can cause further damage to the tire. It could fail
suddenly, which can result in loss of vehicle control and lead to
serious personal injury or death. To insure safety, go to your
authorized Toyo Tires dealer for professional inspection and
proper tire repairs.
• Cosmetic Tire Alterations Can Be Dangerous! Remember — Do
n
ot perform or allow anyone to perform any alterations to your
tires. Alterations may prevent proper performance, leading to
tire damage, which could result in sudden tire failure and loss of
vehicle control and lead to serious personal injury or death.
