8. 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 unap-
proved 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
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).
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
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 be sure of the exact interchangeability to maintain proper
vehicle dynamics.
Please be aware that it is important that, before fitting the suggested tires,
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 combina-
tion with the technical specifications for the chassis and vehicle.

12. Storage
Should you need to store tires after removal from a vehicle (as in the case
of winter tires), they should be stored in a cool, dry place. 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).
13. 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.
14. 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, verify
that all your valves have proper valve caps. Replace as necessary, since
the valve cap is also a seal against pressure loss.
15. Tire Demounting and Mounting
Tire fitting is best left to professionals who have the proper tools and
equipment to perform the task properly and safely. Your tires should be
mounted or demounted, using Tire and Rubber Association of Canada
procedures or the vehicle manufacturers’ recommendations. 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.

16. Tire/Wheel Alignment and Balancing
Tire/Wheel alignment specifications are issued by your vehicle manu-
facturer and your vehicle must be kept within these tolerances. You
should have your alignment checked annually or whenever you notice
any irregular wear or vibrations. Tire/ Wheel assemblies should be
balanced each time a tire is fitted to a wheel. Tire/Wheel alignment and
balancing are important for safety and maximum performance and
mileage from your tires.

WHAT IS NOT COVERED?
This Limited Warranty does not cover the following categories of claims:
Rapid Treadwear: Original equipment tires are not guaranteed to last a
specified number of miles.
Damage from road hazards (not limited to cuts, snags, bruises, impact
breaks, bulges, punctures, stone drills, chips, and scales), fire, theft, or
collision.
Conditions arising from improper tire/vehicle maintenance or use, not
limited to:
•Irregular or excessive treadwear due to: Incorrect inflation; overload-
ing; vehicle misalignment; failure to rotate tires; and poor or defective
mechanical condition of brakes, shocks, and wheels; or other factors
attributable to the vehicle or wheel.
• Any tire which has been run with low air pressure or while flat.
• Damage due to abuse; vandalism; tire alteration; tire spinning; racing;
or other competitive activities.
• Damage, corrosion, or deterioration from using oil-based chemicals,
water-based sealers, balancing substances, or flammable gases.
• Damage from improper use of tire chains.
Tires with the DOT identification number removed or rendered illegible.
Improper mounting, balancing or repair, not limited to:
• Improper tire mounting, or tire/wheel assembly imbalance.
• Damage from incorrect mounting or dismounting of the tire, incorrect
wheel size, water or other material trapped inside the tire during
mounting, or failure to keep the tires balanced.
• Damage resulting from improper repair materials or procedures.

RECOMMENDATIONS FOR SAFE TIRE INFLATION
•If you must inflate your tires when they are hot, add 4 pounds per
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
recommended 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 1 pound per square inch (1 psi) per month, the tire,
the valve, or the wheel may be damaged. Consult your authorized
Toyo Tires dealer for an inspection.
• Over-inflation can cause the tire to be more susceptible to impact
damage.
• Over-inflation or underinflation may adversely affect vehicle
handling.
• Remember to check your spare tire. Consult your vehicle Owner ’s
Manual 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 help
guard against air leakage.
WARNING!
Never inflate a tire unless it is secured to the vehicle or a tire
mounting 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 pres-
sure at least once per month when the tires are cold
(for example, after being parked overnight). Tire pres-
sure warning systems are not a substitute for regular
tire pressure maintenance.
WARNING!
If your vehicle is equipped with TPMS, read the vehicle Owner ’s
Manual 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.
IDENTIFYING DAMAGED TIRES
•If your tire strikes a road hazard at any speed, internal tire damage could
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
damage 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 recommended as a
safety precaution.
• Indications of impact damage include, but are not limited to, a bubble
or a blister on the outside of the tire.
• Have your dealer inspect your tires if you see anything unusual or if
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 qualified
tire service person. It may be necessary to have the tire removed from
the wheel for a complete inspection.

•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.

•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.
