FOLLOW THESE ADDITIONAL GUIDELINES
When installing only two tires, fit the tires with the deepest tread
de
pth on the rear axle. If radials and non-radials must be fitted to the
same vehicle, fit radials on rear axle. Never mix radials and
non-radials on the same axle. When fitting winter tires or all-season
tires to performance vehicles, always fit in sets of four. It is not
recommended to fit tires with different speed ratings. If tires with
different speed ratings are installed on a vehicle, they should be
installed with like pairs on the same axle.
The speed capability of the vehicle will become limited to that of the
lo
west speed rated tires.
Use of lift kits with some vehicle/tire combinations can cause
in
stability. When changing tire sizes, always consult dealer for
optimum rim width and carefully check vehicle/tire clearances.
RETREADED TIRES
Retreaded passenger and light truck tires are not warranted by
Goodyear® for any reason. Speed ratings and US Department of
Transportation (DOT) test compliance certifications are voided for
retreaded tires.
DO MAINTAIN VEHICLE SUSPENSION, WHEEL ALIGNMENT AND
BA
LANCE AND ROTATE YOUR TIRES
Lack of rotation, worn suspension parts, underinflation/ overinflation,
whe
el imbalance and misalignment can cause vibration or irregular tire
wear. Rotate your tires according to your vehicle manufacturer’s
recommendations or at maximum intervals of 6,000 miles / 10,000 km.

CAUTION!
Never substitute a “Standard Load” (SL) tire for an Extra Load
( X
L) or Reinforced tire. If the vehicle was originally equipped
with “Extra Load” (XL) or Reinforced tires, replace those tires with
similar-sized Extra Load (XL) or Reinforced tires.

NOTE:
your vehicle manufacturer may provide additional tire warranty
co
verage over and above what is provided by Michelin. Consult your
vehicle Owner’s Manual for further information.
NOTE:
Some Michelin® Self-Supporting Zero Pressure (ZP) tires can only be
mo
unted on special SH-M (Symmetric Hump - Modified) wheels.
These tires bear the special SH-M designation, molded into the side -
wall of the tire, next to the ZP designation. DO NOT MOUNT A TIRE
WI
TH THE SH-M DESIGNATION ON THE SIDEWALL ON A
STANDARD WHEEL. DOING SO VOIDS THIS LIMITED
WARRANTY AND COULD CAUSE THE TIRE TO BECOME
UNSERVICEABLE AT LOW OR ZERO PRESSURE, RESULTING IN
SERIOUS PERSONAL INJURY OR DEATH.
Treadwear – Mileage Warranty Coverage for Michelin® Passenger
an
d Light Truck Tires
Michelin® passenger and light truck tires are covered by a
ma
nufacturer’s limited warranty for treadwear. For the mileage
warranty associated with a specific tire line, please see your
Michelin® tire retailer or visit us at
www.michelinman.com/home
.
Some vehicles come from the vehicle manufacturer with “split
fi
tments” – meaning different size tires on the front and rear axles.
Because these tires cannot be rotated as recommended by Michelin®,
the mileage warranty on each rear tire will cover half the number of
miles as the standard mileage warranty for that particular tire design.
Michelin® Self-Supporting Zero Pressure (ZP) tires have the same
mileage warranty as the standard tire line of which they are a part, up
to but not exceeding 30,000 miles. DOT-approved competition tires
(e
.g., Michelin® Pilot® Sport Cup tires) are excluded from any
mileage warranty. Michelin® Winter tires must be used during winter
months only, defined as a period beginning on or after September 1st
of a given year and ending no later than April 30th of the following
year. Michelin® winter tires require documentation of the timing of
the installation and removal of the tires each winter to maintain
coverage under the limited warranty for treadwear.
An important reminder:
No tire manufacturer can guarantee you a certain number of miles
fr
om a given tire. Driving habits, driving conditions, road conditions,
and vehicle maintenance all play a part in the tread life of a tire. If a
tire does not reach the warranted mileage, and the owner of the tires

Furthermore, a tire’s speed rating does not imply that vehicles can be
safely driven at the maximum speed for which the tire is rated,
particularly under adverse road and weather conditions or if the
vehicle has unusual characteristics.
Michelin® highway passenger tires that do not have a speed symbol on
th
e sidewall have a maximum speed rating of 105 mph (170 km/h).
Li
ght truck highway tires that do not have a speed symbol on the
sidewall of the tire have a maximum speed rating of 87 mph (140 km/h).
Michelin® Winter tires that do not have a speed symbol on the
si
dewall or tires with Q symbols have a speed rating of 100 mph
(1
60 km/h). Winter tires with a speed symbol have a maximum speed
ra
ting in accordance with the symbol.
The speed and other ratings of retreaded tires are assigned by the
re
treader and replace the original manufacturer’s ratings.
IMPORTANT: In order to maintain the speed capability of the vehicle,
re
placement tires must have speed ratings equal to or higher than
those fitted as original equipment (as indicated on the vehicle tire
placard or Owner’s Manual). If tires with lower speed ratings are
fitted, the vehicle’s handling may be affected and the speed capability
of the vehicle will be lowered to the maximum speed capability of the
replacement tires as indicated in the following table.
REMEMBER ..
.High speed driving can be dangerous and may
damage your tires.
AND... When driving at highway speeds, correct inflation pressure is
e
specially important.

alignment and balance checked immediately. Tires which have been
ran underinflated will show more wear on the shoulders than in the
center of the tread.
TIRE MIXING
Michelin® tires are radial tires and for best performance it is
re
commended that the same size and type of tire be used on all four
wheel positions. Before mixing tires of different types in any
configuration on any vehicle, be sure to check the vehicle
manufacturer’s owner‘s manual for its recommendations.
It is especially important to check the vehicle manufacturer’s Owner’s
Ma
nual when mixing, matching, or replacing tires on 4-wheel drive
vehicles, as this may require special precautions.
MICHELIN® DOES NOT RECOMMEND MIXING PAX® SYSTEM
TI
RES WITH NON-PAX TIRES/SELF-SUPPORTING ZERO
PRESSURE (ZP) TIRES WITH NON-ZP TIRES OTHER THAN THE
TEMPORARY USE OF THE SPARE IF THE VEHICLE IS SO
EQUIPPED.
WINTER DRIVING
Tires which meet the US Tire Manufacturers Association (USMTA)
de
finition of snow tires are marked M/S, or M&S. On such tires, this
designation is molded into the sidewall. Tires without this notation
are not recommended or Winter driving.
While All-Season tires are designed to provide reliable
performance in some Winter conditions, the use of four
Wi
nter tires is recommended for optimal performance.
Tires designate for use in severe Winter conditions are
marked on at least one sidewall with the letter “M”
TIRE ROTATION AND REPLACEMENT
To obtain maximum tire wear, it may be necessary to rotate your tires.
Re
fer to your vehicle owner’s manual for instructions on tire rotation.
If you do not have an owner‘s manual for your vehicle, Michelin®
recommends rotating your tires every 6,000 to 8,000 miles (10,000 to
12
,000 km).
Monthly inspection for tire wear is recommended. Your tires should
be
rotated at the first sign of irregular wear, even if it occurs before
6,000 miles (10,000 km). This is true for all vehicles.

ROAD HAZARD REPLACEMENT PROGRAM
Most patterns sold by NEXEN TIRE are covered by a road hazard
wa
rranty that protects the consumer against non-repairable damage
caused by puncture, snag, cut, bruise or impact break. Typical road
hazards are nails, glass, potholes and other debris. Covered tires will
be eligible for a free replacement for the first 3/32" of original tread
depth, or for a period of two years from the date of purchase;
whichever comes first. If the DOT number on the tire is greater than
two years from the adjustment date, an invoice showing date of
purchase is necessary. The cost of mounting, balancing and any other
service charges including applicable taxes are required to be paid by
the consumer.

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

5. DOT Street Legal Competition Tires
P Zero Trofeo and P Zero Corsa tire lines use special tire construction
an
d 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
ti
res, resulting in reduced tread life.
6. Winter Tires
The standard Pirelli tires may be effective in light snow conditions.
Ho
wever, 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
sa
fety 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
ve
hicles on which they 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
Pr
essure Monitoring System (TPMS).
The mounting of tires and installation of the TPMS should be carried
ou
t by a specialized dealer.
