•Tires improperly repaired or with repairs not conforming to Tire and
Rubber Association of Canada standards, or with section repairs, or
with a self-vulcanizing plug only or patch only.
•Tires which have been recapped, or retreaded, or regrooved.
•Tires used in racing or other competitive events.
•Tires removed in multiples when only one tire can be claimed, or is
suspect of a claim.
•Ride related anomalies after the first 2/32” of treadwear.
•Tires which become unserviceable because of tire operation in excess of
tire/wheel manufacturers’ specifications and recommendations, in-
cluding spinning.
•Tires which become unserviceable because of a mechanical irregularity
in the vehicle such as misalignment, defective brakes, defective shock
absorbers or struts, or improper rims.
•Tires damaged by fire, chemical corrosion, vandalism, wrecks, chains,
theft, run while flat, under inflated, over inflated or abused during
servicing.
•Tires affected by flat spotting caused by improper transport or storage.
•Tires which became unserviceable because of road hazard injuries (e.g.,
nails, glass, metal objects) or other penetrations or snags, bruises or
impact damage, except for those Run Flat lines/sizes specifically
covered by the Pirelli Road Hazard Policy.
•Tires with weather / ozone cracking which were purchased more than
four years prior to presentation for adjustment. (If no proof of
purchase date is available, the warranty will be four years from the
DOT date).
•Summer tires that developed surface cracks due to use in low ambient
temperatures. These include P Zero Silver, P Zero Trofeo, P Zero Corsa
System, P Zero, P Zero Rosso™, P Zero Nero, Cinturato P1, Cinturato
P7, Scorpion Zero™ and Scorpion Verde.

10. Tire Rotation
Pirelli recommends that you follow the tire rotation procedure as defined
in your vehicle owner ’s manual. If there is no procedure, PTI recom-
mends 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 tires
may be repaired if the diameter does not exceed 6 mm. The repair
material used must seal the innerliner 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 6 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.
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 TIRE DOES NOT ENDORSE:
•The use of tire sealants in Pirelli tires to repair, even temporarily, a
puncture;
•The repairing of V, W, Y or Z Speed Rated tires;
•The repairing of Run Flat 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, the
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 flat
spots in the tread may indicate alignment or other problems with the
tires or the vehicle. Consult your authorized Toyo Tires dealer.
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.
IDENTIFYING DAMAGED WHEELS
Periodically check to see if any of the following symptoms exist, in which
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
tightening could cause this.)
•If there are cracks in the wheel.
WORN OUT TIRES
Tires must be replaced when tread is worn to 2/32” (1.6 mm). Treadwear
indicators on Toyo tire treads show the 2/32” depth (1.6 mm). Most states
require that tires be replaced when the tread depth is worn to 2/32”
(1.6 mm). Tires may lose sufficient wet and snow traction before reaching
2/32” (1.6 mm) of wear. Many wet weather accidents result from
skidding on worn out tires.
Excessively worn tires are more susceptible to penetrations. Consider
replacing your tires earlier if you drive in snow or wet conditions.

WARNING!
Continued operation of your vehicle with excessively worn tires
may lead to loss of vehicle control in adverse weather conditions,
tire failure, and serious personal injury or death.
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
inspected 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.
WARNING!
•Before having your tire repaired, tell your authorized Toyo Tires
dealer if you have used an aerosol puncture sealant to inflate/ seal
the tire. Aerosol puncture sealants could contain a highly flam-
mable, explosive gas.
•Driving on an improperly repaired tire is dangerous. An improper
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 not
perform or allow anyone to perform any alterations to your tires.
Alterations may prevent proper performance, leading to tire dam-
age, which could result in sudden tire failure and loss of vehicle
control and lead to serious personal injury or death.
•Never repair a tire with 2/32” (1.6 mm) or less tread remaining. At this
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
diameter. Such tires cannot be properly repaired and must be replaced.
•Repairs of all tires (radial and non-radial) must be of the plug and
inside patch type. Using plugs alone on any type of tire is not a safe
repair.

•Do not use a rope type plug for repair. A tire must be removed from the
wheel and inspected for interior damage. Any tire repair done without
removing the tire from the wheel is improper and unsafe.
•Never repair a tire with a puncture or other damage outside the tread
area. Do not repair sidewall damage. Such tires cannot be properly
repaired and must be replaced.
