TIRE MIXING
Michelin® tires are radial tires and for best performance it is recommended 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 Manual when
mi
xing, matching, or replacing tires on 4-wheel drive vehicles, as this may require special
precautions.
MICHELIN® DOES NOT RECOMMEND MIXING PAX® SYSTEM TIRES WITH NON-PAX®
T I
RES/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) definition 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 Winter tires is recommended for optimal
p e
rformance. 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. Refer 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
s i
gn of irregular wear, even if it occurs before 6,000 miles (10,000 km). This is true for
a l
l vehicles.
When rotating tires with a directional tread pattern, observe the arrows molded on the
s i
dewall which show the direction the tire should turn. Care must be taken to maintain
the proper turning direction.
Some Tire Pressure Monitoring Systems (TPMS) may not recognize that a tire has been
m o
ved to a different position on your vehicle. Make certain that your TPMS system is
reset, if necessary, so as to correctly identify the location of each tire on your vehicle.
Refer to your vehicle owner’s manual or your vehicle dealer.
Determine whether rotated tires require tire inflation adjustment as front and rear
p o
sition tire pressure may vary according to the vehicle manufacturer’s specification due
to the actual load on that wheel position. Some vehicles may have different sized tires
mounted on the front and rear axles, and these different sized tires have rotation
restrictions. Always check the vehicle owner’s manual for the proper rotation
recommendations.
MICHELIN®
133
Full-size Spare
Full-size spare tires (not temporary spares) of the same size and construction should be
u s
ed in a five tire rotation. Always check the inflation pressure of the full-size spare
immediately before incorporating it into rotation. Follow the vehicle manufacturer’s
recommended pattern for rotation, or if not available, see a qualified tire technician.
Replacement of Two Tires
It is recommended that all four tires are replaced at the same time. However, when only
t w
o tires are replaced, the new tires should be put on the rear. The new tires, with deeper
tread, may provide better grip and water evacuation in wet driving conditions.
CUSTOMIZATION OF TIRES, WHEELS, OR SUSPENSION ON SUVS AND LIGHT
TRUCKS
Due to their size, weight and higher center of gravity, vehicles such as SUVs and light
trucks do not have the same handling characteristics as automobiles. Because of these
differing characteristics, failure to operate your SUV/truck in a proper and safe manner
can increase the likelihood of vehicle rollover. Modifications to your SUV/truck tire size,
tire type, wheels or suspension can change its handling characteristics and further
increase the likelihood of vehicle rollover. Whether your SUV/truck has the original
equipment configuration for tires, wheels and suspension or whether any of these items
have been modified, always drive safely, avoid sudden, sharp turns or lane changes and
obey all traffic laws. Failure to do so may result in loss of vehicle control leading to an
accident and serious injury or death.
TIRE ALTERATIONS
Do not make or allow to be made any alterations on your tires. Alterations may prevent
proper performance, leading to tire damage which can result in an accident. Tires which
become unserviceable due to alterations such as truing, whitewall inlays, addition of
balancing or sealant liquids, or the use of tire dressing containing petroleum distillates
are excluded from warranty coverage.
REPAIRS WHEREVER POSSIBLE, SEE YOUR MICHELIN® TIRE RETAILER AT ONCE
If any MICHELIN® tire sustains a puncture, have the tire demounted and thoroughly
inspected by any MICHELIN® tire retailer for possible damage that may have occurred.
A tread area puncture in any MICHELIN® passenger or light truck tire can be repaired
provided that the puncture hole is not more than 1/4 inch in diameter, not more than
o n
e radial cable per casing ply is damaged, and the tire has not been damaged further
by the puncturing object or by running underinflated. Tire punctures consistent with
these guidelines can be repaired by following the US Tire Manufacturers Association
(USTMA) recommended repair procedures.
TIRE REPAIRS
Repairs of all tires must be of the combined plug and inside patch type. Your MICHELIN®
PAX® System tires must be removed from the wheel for inspection prior to repair. Plug
only repairs are improper. A tire should be removed from the rim and inspected prior to
MICHELIN®
134
repair. Any tire repair done without removing the tire from the rim is improper. An
improperly repaired tire will cause further damage to the tire by either leaking air or
allowing air, moisture and contaminants to enter the structure of the tire. An improperly
repaired tire can fail suddenly at a later date.
Never repair a tire with less than 2/32nds of an inch tread remaining. At this tread depth,
th
e tire is worn out and must be replaced.
STORAGE
Tires contain waxes and emollients to protect their outer surfaces from ozone and
weather checking. As the tire rolls and flexes, the waxes and emollients continually
migrate to the surface, replenishing this protection throughout the normal use of the tire.
Consequently, when tires sit outdoors, unused for long periods of time (a month or more)
their surfaces become dry and more susceptible to ozone and weather checking and the
casing becomes susceptible to flat spotting. For this reason, tires should always be
stored in a cool, dry, clean, indoor environment. If storage is for one month or more,
eliminate the weight from the tires by raising the vehicle or by removing the tires from
the vehicle. Failure to store tires in accordance with these instructions could result in
damage to your tires or premature aging of the tires and sudden tire failure.
When tires are stored, be sure they are placed away from sources of heat and ozone such
a s
hot pipes and electric generators. Be sure that surfaces on which tires are stored are
clean and free from grease, gasoline or other substances which could deteriorate the
rubber. Tires exposed to these materials during storage or driving could be subject to
sudden failure.
FOLLOW THESE MOUNTING RECOMMENDATIONS
Tire changing can be dangerous and must be done by professionally trained persons
using proper tools and procedures as specified by the Rubber Manufacturers
Association (RMA). PAX® System tires must be mounted and dismounted only by
specially trained, authorized PAX® System retailers, utilizing PAX® System authorized
equipment.
Your tires should be mounted on wheels of correct size and type and which are in good,
cle
an condition. Wheels that are bent, chipped, rusted (steel wheels) or corroded (alloy
wheels) may cause tire damage. The inside of the tire must be free from foreign material.
Have your retailer check the wheels before mounting new tires. Mismatched tires and
rims can explode during mounting. Also, mismatched tires and rims can result in
dangerous tire failure on the road. If a tire is mounted by error on the wrong-sized rim, do
not remount it on the proper rim, scrap it. It may have been damaged internally (which is
not externally visible) by having been dangerously stretched and could fail on the
highway.
Old valves may leak. When new tubeless tires are mounted, have new valves of the
c o
rrect type installed. Tubeless tires must only be mounted on wheels designed for
tubeless tires i.e., wheels which have safety humps or ledges. As with any other tire air
valve, the PAX® System valve stem-pressure sensor combination must be in good
MICHELIN®
135
condition to assure its performance. Always utilize valve caps capable of containing the
tire’s air pressure, should the valve core leak. The valve cap is the primary seal against
air loss.
It is recommended that you have your tires and wheels balanced. Tires and wheels which
a r
e not balanced may cause steering difficulties, a bumpy ride, and irregular tire wear.
SPECIAL MOUNTING INSTRUCTIONS FOR PAX® SYSTEM TIRES
PAX® System wheels are different from all other wheels. Never attempt to mount a
non-PAX® System tire on a PAX® System wheel, or a PAX® System tire on a non-PAX®
System wheel. Attempting to do so could cause serious injury or death. All PAX® System
components (tire, wheel, support ring, pressure sensor and gel) must be utilized. Never
utilize a PAX® System tire and wheel without every other properly functioning component
part, correctly installed by an Authorized PAX® System retailer. The PAX® System must
be used on all wheel positions.
After a low or zero pressure driving event, the PAX® System tire and wheel may be hot to
th
e touch. Always allow a PAX® System tire to cool before attempting to handle it. Failure
to do so could result in injury.
SPECIAL MOUNTING INSTRUCTIONS FOR SELF-SUPPORTING ZERO PRESSURE™ (ZP)
T I
RES
ZP tires can be more difficult to mount than conventional tires. They should be mounted
a n
d demounted only by a properly trained tire professional. ZP tires can generate a
tremendous amount of heat when run at low or zero pressure. ALWAYS ALLOW A ZP TIRE
TO COOL BEFORE ATTEMPTING TO HANDLE IT. FAILURE TO DO SO COULD RESULT IN
INJURY.
MICHELIN® ZP tires are tubeless tires designed to operate in emergency conditions at
lo
w or zero air pressure.
MICHELIN® SELF SUPPORTING Zero Pressure™ (ZP) TIRES AND SPECIAL SYMMETRIC
H U
MP-MODIFIED (SH-M) WHEELS
Some MICHELIN® ZP tires can only perform with zero pressure capability when mounted
o n
special SH-M wheels. These tires bear the SH-M designation immediately following
the ZP designation on the sidewall of the tire. DO NOT MOUNT ZP TIRES WITH THE SH-M
DESIGNATION ON STANDARD WHEELS. IN SUCH APPLICATIONS, THE TIRES MAY
BECOME UNSERVICEABLE AT LOW OR ZERO PRESSURE, CAUSING SERIOUS PERSONAL
INJURY OR DEATH.
SPECIAL MOUNTING INSTRUCTIONS FOR MICHELIN® TRX™ TIRES
The MICHELIN® TRX™ tire is a tubeless tire that must only be mounted on special wheels
( T
R or JM type) with millimetric seat diameter. If TRX tires are mounted on standard
wheels, they will not retain air due to an air escape feature designed into the bead area
of these tires.
Do not try to override this feature by mounting TRX tires with tubes. The MICHELIN®
T R
X™ tire must be used on all wheel positions.
MICHELIN®

replaced based on their calendar age alone. However the older a tire the greater the
chance that it will need to be replaced due to the service-related evolution or other
conditions found upon inspection or detected during use.
While most tires will need replacement before they achieve 10 years, it is recommended
t h
at any tires in service 10 years or more from the date of manufacture, including spare
tires, be replaced with new tires as a simple precaution even if such tires appear
serviceable and even if they have not reached the legal wear limit. For tires that were on
an original equipment vehicle (i.e., acquired by the consumer on a new vehicle), follow
the vehicle manufacturer’s tire replacement recommendations, when specified (but not
to exceed 10 years).
The date when a tire was manufactured is located on the sidewall of each tire.
C o
nsumers should locate the Department of Transportation (DOT) code on the tire which
begins with DOT and ends with the week and year of manufacture. For example, a DOT
code ending with “2204” indicates a tire made in the 22nd week (May) of 2004.
REMEMBER TO AVOID DAMAGE TO YOUR TIRES AND POSSIBLE ACCIDENT
• CHECK TIRE PRESSURE AT LEAST ONCE EACH MONTH WHEN TIRES ARE COLD AND BEFORE LONG TRIPS.
• D O NOT UNDERINFLATE/OVERINFLATE.
•
DO NOT OVERLOAD.
•

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.

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 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 with the same
t r
ead 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
sa
me 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
o f
four.
When replacing tires on light truck vehicles, you should always follow the vehicle
m a
nufacturer’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
h a
ve 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
a l
lowed 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.
TO MAINTAIN PROPER VEHICLE DYNAMICS AND LOAD CARRYING CAPACITY,
R E
PLACEMENT TIRES MUST ALWAYS HAVE A LOAD INDEX AND SPEED SYMBOL EQUAL
TO OR GREATER THAN THOSE FITTED AS ORIGINAL EQUIPMENT.
When making plus size fitments, you should consult with the dealer regarding any
s u
spension or braking system modifications which may be recommended for the vehicle.
9. Tire Inspection
As a minimum, tires (including the spare tire) should be examined and air pressure
checked monthly and always prior to long trips. They should also be examined if you
strike any unusual object on the road. Tires showing bulges, cracks, cuts, penetrations
or uneven wear must be dismounted and examined by an authorized Pirelli tire dealer
