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 PERFORMANCE, ULTRA HIGH
P E
RFORMANCE): 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 design and compound
m a
de 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 Q

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 patterns and rubber
c o
mpounds 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 either 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.
Underinflation causes excessive flexing, deterioration of the tire and rapid wear of the
tread edges. Overinflation results in an uncomfortable ride, a reduced area of tire contact
with the road surface (i.e., smaller tire footprint), higher susceptibility to impact damage
and rapid wear on the tread center.
Inflation pressure must be checked at least once a month and should be checked only
w h
en the tire is cold or before it has been driven. Driving even a short distance
(1 kilometer or 2 to 3 minutes) causes tires to heat up and the air pressure to increase
a p
proximately 4 psi. In case it is necessary to adjust the air pressure in tires that have
been driven, the air pressure should be increased to a gauge reading of 4 psi higher than
the recommended cold inflation pressure.
For Example Only:
WARNING!
Driving on tires with improper inflation pressure is dangerous. These situations can
cause a tire failure, including tread/belt separation, even at a later date, which could
lead to an accident and serious personal injury or death.
Gauge Reading of Hot Tire: 27 PSI
Recommended Cold Inflation Pressure: 26 PSI
Desired Gauge Reading of Hot Tire: 26 PSI + 4 PSI = 30 PSI
Therefore: Add 3 PSI
PIRELLI TIRES

Check the cold inflation pressure on the tires, at least by the next day. Never reduce or
“bleed” pressure from hot tires since your tires will then be underinflated when they cool
down. Always use a reliable pressure gauge.
4. Ultra High Performance (UHP) Summer Tires
Rubber compounds formulated for ultra high performance summer tires can lose
flexibility and may develop random surface cracks at cold temperatures. Therefore extra
care should be used in handling tires in this condition. These compounds are optimized
for maximum dry and wet performance in warm conditions. Special tread compounds in
these tires will have decreased performance, such as lateral and braking traction, at
temperatures below 7° C or when driving on snow or ice. Therefore, it is recommended
to install winter tires in these conditions.
5. DOT Street Legal Competition Tires
P Zero Trofeo and P Zero Corsa tire lines use special tire construction and 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 tires, resulting in
re
duced tread life.
6. Winter Tires
The standard Pirelli tires may be effective in light snow conditions. However, 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 safety 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 vehicles on which
t h
ey 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 Pressure Monitoring
S y
stem (TPMS).
The mounting of tires and installation of the TPMS should be carried out by a specialized
d e
aler.

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 manufacturer 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.

FOUR-WHEEL DRIVE (4WD) AND ALL-WHEEL DRIVE (AWD) VEHICLES
If no instructions for tire mixing appear in the vehicle Owner’s Manual, follow these
guidelines:
• D o not mix tire sizes. All four tires must be marked with the same tire size, unless
o
therwise specified by the vehicle manufacturer. This also applies to winter/snow
tires.
• D o not mix tread pattern types such as all-terrain and all- season.
STUDLESS WINTER/SNOW TIRES
• It is always preferable to apply winter/snow tires to all wheel positions, including dual
tires, to maintain vehicle mobility and control.
• I f winter/snow tires are applied to the f
ront axle of any vehicle, winter/snow tires must
also be installed on the
rear axle. DO NOT apply winter/snow tires only to the front
axle. This applies to all passenger and light truck vehicles, including front-wheel- drive,
4WD, and AWD vehicles.
• If winter/snow tires are installed on the rear axle of any vehicle, it is recommended
(but not required) that they also be installed on the
front axle.
STUDDED WINTER/SNOW TIRES
• Studded winter/snow tires have higher traction qualities under most winter weather conditions.
• I f studded winter/snow tires are installed on the f
ront axle of any vehicle, studded
winter/snow tires must also be installed on the
rear axle. DO NOT apply studded
winter/snow tires only to the front axle.
• If studded winter/snow tires are installed on the rear axle of any vehicle, it is strongly
recommended that they should also be installed on the
front axle. Only if studded
winter/snow tires are installed on all wheel positions of a vehicle will optimum
handling characteristics be achieved.
WARNING!
Unless winter/snow tires on the rear axle have comparable traction qualities to the
tires on the front axle, the vehicle may experience adverse handling characteristics.
This may result in loss of vehicle control, which can lead to serious personal injury or
death.
WARNING!
Installing only two studded winter/snow tires on the front axle of any vehicle (including
front-wheel-drive vehicles) without studded winter/snow tires on the rear axle can
cause adverse vehicle handling characteristics. This can result in a loss of vehicle
control, which could cause serious personal injury or death.

TOWING OR USE OF SLIDE-IN TRUCK CAMPERS
If you are towing a trailer or using a slide-in truck camper, refer to your vehicle Owner’s
Manual.
WINTER (SNOW) TIRES
Winter driving presents special challenges for vehicle handling. The use of
winter tires, studs, and chains, while improving traction performance in snow
a n
d ice, requires additional caution and care with regard to braking, cornering,
and speed. It is important to drive with care not only on snow and ice, but on
dry and wet roads as well.
• T raction is considerably reduced as snow tires approach 50% tread wear, and replace -
m
ent should be considered in order to maintain effectiveness in heavy snow condi-
tions.
• T ire speed rating – When lower-speed-rated winter tires replace higher-speed-rated
t
ouring and high performance all-season radial tires, do not exceed the lower-rated
speed.
• F ollow recommendations in the vehicle Owner’s Manual for winter tires, studs, and
c
hains.
• C onsult your tire dealer, the US Tire Manufacturers Association (USTMA) website
h
ttps://www.ustires.org/ , or your state’s Department of Transportation (DOT) for infor -
mation regarding regulatory and seasonal restrictions for stud usage.
• A lso see the “Tire Mixing” section in this manual for more details.
•
Toyo Tires® recommends that snow tires be installed in matched sets of four.
WARNING!
Spinning a tire to remove a vehicle stuck in mud, snow, or wet grass can be
dangerous. This could cause serious personal injury or death to a bystander or
passenger and extensive vehicle damage. A tire spinning at a speedometer reading
above 35
mph (55 km/h) can reach a speed capable of disintegrating a tire with
e x
plosive force within a matter of seconds. Under some conditions, a tire may be
spinning at twice the speed shown on the speedometer. Never spin a tire above a
speedometer reading of 35 mph (55 km/h). Never allow anyone to stand near or
d i
rectly behind the spinning tire. Do not spin if a drive wheel is off the ground.
WARNING!
Studded tires may require longer braking distances on dry or wet paved surfaces.
Failure to allow for adequate braking distance could result in serious personal injury or
death.

per month and before extended operation. Use a tire gauge to check pressure and
maintain it per the vehicle manufacturer’s recommendations (on vehicle placard or in
Owner’s Manual). Do not reduce pressure when tire is hot and do not inflate a cold tire
higher than limits molded on the tire’s sidewall. Do not overlook spare tire inflation
pressure.
Tire Tread
Tires must be replaced when the depth of the tread reaches 2/32 of an inch (1.6 mm).
YO
KOHAMA® tires are manufactured with tread wear indicators molded into the tire
grooves which indicate tread wearout. As tires wear down to 2/32 of an inch (1.6 mm),
a n
d tread depth is reduced, tire traction is reduced during rainfall and winter road
conditions. Visual tire inspection therefore becomes more crucial as the tires wear out.
Hard Braking
You must inspect your tires after any hard braking situations or after tires have slid on
the pavement. This can cause a flat spot or other damage to the tread of the tire.
Spinning
• Do not allow tires to spin at speeds greater than 35 mph if vehicle becomes stuck.
• D o not stand behind a spinning tire while attempting to push a vehicle. Speed and
f
orce can cause a tire to disintegrate and explode and may cause property damage
and/or personal injury.
