2. Tire Categories
ALL SEASON TIRES (ALL WEATHER TIRES): Tires that are designed
to
perform in a variety of road conditions in all seasons of the year. An
all season tire will carry “M+S”, “M&S”, or “M/S” designation on the
sidewall. All Season tires may carry a Limited Treadwear Warranty
depending on line.
SUMMER TIRES (MAXIMUM PERFORMANCE, HIGH
PE
RFORMANCE, ULTRA HIGH PERFORMANCE): Summer
Performance tires offer superior handling, grip and cornering ability
compared to standard tires. They are rated for operation at higher
speeds. Maximum Performance, High Performance and Ultra High
Performance categories each have different performance
characteristics, UTQG ratings and rate of wear depending on line.
Some lines may carry a limited treadwear warranty.
WINTER TIRES (SNOW TIRES): A winter tire is a tire with a tread
de
sign and compound made specifically for snowy and icy conditions
and is identified by M&S, M+S or M/S markings on the sidewalls.
Tires designed for use in severe snow conditions are further identified
with a pictograph of a mountain with a snowflake on the sidewalls
and must meet specific snow performance test requirements. Pirelli
Winter tires do not carry a mileage warranty.
The information provided above is an overview of tire types. Tread
pa
tterns and rubber compounds vary among the seasonal tire types
and provide varying performance characteristics and limitations
based on your individual needs and vehicle specifications. Summer
performance tires are different than winter and all season types. To
determine which Pirelli lines carry a Limited Treadwear Warranty,
please refer to The PTI Treadwear Mileage Warranty Conditions and
Mileage Warranty sections found in this document.
3. Pressure Recommendations
Recommended tire inflation pressures for your vehicle can be found
ei
ther on your vehicle’s tire placard or in your vehicle owner’s
manual. Correct pressures are related to load, speed and vehicle
handling and are vital for even braking, maximum traction and good
tire life. Under no circumstances should your tire’s cold inflation
pressure be less than that indicated on your vehicle’s tire placard or in
your vehicle owner’s manual or higher than the maximum cold
inflation pressure molded on to the tire’s sidewall. Under inflation
causes excessive flexing, deterioration of the tire and rapid wear of the

12. Storage
Should you need to store tires after removal from a vehicle (as in the
ca
se 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
“T
ubeless”. 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
th
e 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
eq
uipment 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
ma
nufacturer 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
cl
aims:
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
br
eaks, bulges, punctures, stone drills, chips, and scales), fire, theft, or
collision.
Conditions arising from improper tire/vehicle maintenance or use,
no
t limited to:
• Irregular or excessive treadwear due to: Incorrect inflation; over -
l
oading; vehicle misalignment; failure to rotate tires; and poor or
de
fective 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;
r
acing; or other competitive activities.
• Damage, corrosion, or deterioration from using oil-based chemicals,
w
ater-based sealers, balancing substances, or flammable gases.
• Damage from improper use of tire chains.
T
ires with the DOT identification number removed or rendered
il
legible.
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, incor -
r
ect wheel size, water or other material trapped inside the tire
du
ring mounting, or failure to keep the tires balanced.
• Damage resulting from improper repair materials or procedures.
F
ailure to meet conditions of this Limited Warranty, not limited to:
• Any tire that is not an Eligible Tire.
•
Any tire for which mileage and tire rotation records are not avail -
a
ble or verifiable.
• Any tire not presented and available for Toyo Tires’ inspection.
•
Any tire worn beyond the treadwear indicators (less than 2/32” of
r
emaining tread).
• Uniformity issues after the first 25% of treadwear.
TOYO TIRES® – LIMITED WARRANTY

• When two new tires have been installed onto the rear axle positions,
they are to be kept on the rear but rotated from side to side. This is
recommended after installing two new tires to the rear position, or
if you discover significant tread depth differences between the front
and rear positions during rotation intervals.
REPLACING ONE TIRE
• Replacing a single tire on a vehicle can have an adverse effect on
s
uspension systems, gear ratios, transmission, and tire treadwear.
• If single tire replacement is unavoidable, it is recommended that the
s
ingle new tire be paired with the tire that has the deepest tread and
both be placed on the rear axle. Placing greater traction on the rear
axle on wet surfaces is necessary to prevent a possible oversteer
condition and loss of vehicle stability.
WHEEL ALIGNMENT AND BALANCING
• Proper wheel alignment and balance are very important consider -
a
tions for safety and getting the maximum mileage from your tires.
Yo
u need to check how your tires are wearing at least once a month.
• Your vehicle may be out of alignment if your tires are wearing
u
nevenly, such as when the inside shoulder of the tire is wearing
faster than the rest of the tread. This condition not only shortens the
life of your tires, it adversely affects the handling characteristics of
your vehicle, which could be dangerous. If your tires show irregular
wear, have your vehicle’s alignment checked immediately.

UNIFORM TIRE QUALITY GRADING (UTQG)
The Uniform Tire Quality Grading (UTQG) standards are intended to
a s
sist you in making an informed choice in your purchase of
passenger car tires by providing information indicating relative
performance in the areas of treadwear, wet stopping traction, and
temperature resistance. All passenger car tires must conform to
federal safety requirements in addition to these grades.
• Treadwear - The treadwear grade is a comparative rating based on
t
he wear rate of the tire tested under controlled conditions on a spec -
ified government test track. For example, a tire graded 200 would
we
ar twice as long on the government course as a tire graded 100. It
is wrong to link treadwear grades with your projected tire mileage.
The relative performance of the tires depends upon the actual condi -
