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

PIRELLI TIRES
205
tread edges. Over inflation 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
b e

checked only when the tire is cold or before it has been driven.
Driving even a short distance (1 kilometer or 2 to 3 minutes) causes
ti

res to heat up and the air pressure to increase approximately 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:
Check the cold inflation pressure on the tires, at least by the next day.
N e

ver 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
ti
res 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.
WARNING!
Driving on tires with improper inflation pressure is dangerous.
Th
ese 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

8. Tire Replacement
The tires fitted to your vehicle as original equipment were tested and
ap
proved 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 unapproved 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
w i

th 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
(f
our 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
th
e 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:
22
5/45R17) 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
ti
res, 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 combination with the technical specifications for the
chassis and vehicle.

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.

TIRE PRESSURE BASICS
The combined effect of losing one psi per month over several months
al
ong with a one psi decrease for every 10°F temperature drop could
add up to a severe “run low” condition; consequently, it is important
to check your tires’ inflation pressure at least once per month. Inflation
pressure enables a tire to support its load; therefore, proper inflation
is critical.
HOW TO DETERMINE PROPER TIRE INFLATION PRESSURE
It is impossible to determine whether tires are properly inflated just
by
looking at them.

It is important to check your tires using an accurate tire pressure
gauge, which can be purchased at your tire dealer or auto supply
store.
Under inflation can overload tires. Check the inflation pressure every
mo
nth, including for the spare tire, to make sure it is up to
specification. Check it again before long trips or when carrying extra
weight.
Look for FCA US LLC’s recommended inflation pressure listed on the
Ti
re Information Placard usually located on your vehicle’s door edge,
door post, glove box, or inside the trunk lid.
