visible damage. Bumps, bulges, or cracks in any tire may indicate
detachment within the tire body and require inspection by a qualified
tire professional. If any tire, including the spare, has bumps, bulges, \
cracks, or other visible damage, do not resume driving with that tire. I\
f
you have no other option, you should drive as slowly and cautiously as
possible until you can obtain towing or mechanical assistance. If the
spare tire is not properly inflated, do not resume driving with that tire
unless you have no other option, in which case you should drive only
as slowly as is safely possible in the traffic conditions until you can
both get the spare tire properly inflated and have it checked by a tire
professional to ensure that it is safe to use.
Proper Inflation
Driving On Any Tire That Does Not Have The Correct
Inflation Pressure Is Dangerous
An underinflated tire builds up excessive heat that may result in
sudden tire failure and an accident. If your tires are those that came
as original equipment on your vehicle when it was new, refer to the tire
information placard that came on your vehicle (located in the vehicle’s
door jamb, inside the fuel hatch, or on the glove compartment door),
for the recommended operating pressures. For replacement tires,
ask your Michelin tire retailer for the correct inflation pressure; if you
do not, refer to the tire information placard that came on your vehicle \
(located in the vehicle’s door jamb, inside the fuel hatch, or on the
glove compartment door), for the recommended operating pressures.
These inflation pressures must be maintained as a minimum. Never
exceed the Maximum Pressure rating stated on the tire sidewall. Note
that proper inflation pressures for rear tires may differ from proper
inflation pressures for front tires. The Maximum Pressure rating on the
tire is normally not equal to the placard pressure.

MICHELIN
125
Check the Cold Inflation Pressure in All Your Tires,
Including the Spare, at Least Once Each Month
Failure to maintain correct inflation may result in improper vehicle
handling and may cause rapid and irregular tire wear, sudden tire
failure, loss of vehicle control, and an accident. Therefore, inflation
pressures should be checked at least once each month and before
every long-distance trip. This applies to all tires, including sealant
types and self-supporting tires, which are as susceptible to losing air
pressure as any other type of tire if not properly maintained. Pressures\

should be checked before the tires have been driven on or after they
have been allowed to cool down to the ambient air temperature.
Driving for even a short distance causes tires to heat up and their air \
pressure to increase, and recommended tire pressures are for tires
that have not been heated by recent driving on them.
Underinflation and Overinflation Must Be Checked
with a Tire Pressure Gauge
Tires must be checked monthly with a tire pressure gauge. It is
impossible to determine whether tires are properly inflated by simply
looking at them. It is almost impossible to feel or hear when a tire is \
being run underinflated or overinflated. Use an accurate tire pressure
gauge to check tire pressure each month. Small and inexpensive tire
pressure gauges are available. You should keep one in your vehicle’s
glove box or trunk and use it monthly and as otherwise needed.
Self-Supporting Zero Pressure™ (ZP) Tires at Low
or Zero Air Pressure
The handling characteristics of a vehicle with a deflated Self-
Supporting Zero Pressure (ZP) tire (whether front or rear) are not
the same as those of a vehicle with normally inflated tires. Avoid
high speeds and hard cornering whenever a low-pressure warning is
activated. Even a Self-Supporting Zero Pressure (ZP) tire can build
up excessive heat when run underinflated for an extended period of
time. The length of time and distance a Self-Supporting Zero Pressure
(ZP) tire will perform at low or zero inflation will depend on the severity

MICHELIN
126
of the event causing air loss, the ambient temperature, the speed at
which the tire is operated, and the conditions under which the tire
is operated. In particular, hard braking, cornering, and other sharp
maneuvers will greatly reduce the length of time the tire can perform at\

low or zero inflation. Continuous use of an underinflated tire may lead
to sudden tire failure and an accident. If a tire at low or zero pressur\
e
begins to vibrate or cause difficulty in vehicle handling, replace it
immediately with the temporary spare. If Self-Supporting Zero Pressure
(ZP) tires are supplied as original equipment, refer to the vehicle
owner’s manual for complete details on the low tire pressure warning
system designed to alert you in the event of a low pressure condition.
MICHELIN
® SELF-SUPPORTING ZERO PRESSURE™ (ZP) TIRES
MUST BE USED ONLY WITH AN OPERATIONAL, MICHELIN
APPROVED, LOW TIRE PRESSURE WARNING SYSTEM. Otherwise,
all provisions of the limited warranty are void. For a list of approved \
systems, see your Michelin tire retailer or call 1-800-847- 3435. NOTE:
Some MICHELIN Self-Supporting Zero Pressure (ZP) tires can only be
mounted on special SH-M (Symmetric Hump - Modified) wheels. These
tires bear the special SH-M designation, molded into the sidewall of
the tire, next to the ZP designation. DO NOT MOUNT A TIRE WITH
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. For a list of approved systems, see your participating
Michelin
® tire retailer, or call 1-800-847-3435. For all types of tires,
consult your vehicle owner’s manual or the tire information placard
that came on your vehicle (located in the vehicle’s door jamb, inside
the fuel hatch, or on the glove compartment door) for recommended
operating pressures. Recommended operating pressures will be
provided by a Michelin tire retailer for self-supporting ZP tires. These
inflation pressures must be maintained as a minimum. Never exceed
the Maximum Pressure rating shown on the tire sidewall.

MICHELIN
127
For Self-Supporting Zero Pressure (ZP) Tires, Check
Inflation Pressures as Soon as Possible Following a
Low Pressure Warning
Be certain to ensure that your vehicle’s Tire Pressure Monitoring
System (TPMS) is functioning and is correctly calibrated. Refer to your
vehicle owner’s manual or your vehicle dealer. Low pressure warning
systems are designed to alert the driver to a low inflation situation
in at least one tire on the vehicle. While your ZP tires are designed
to provide continued mobility in the event of an air loss, the sooner
you respond to a warning and take corrective action, the greater the
likelihood that the tire can be returned to service. Always visually
inspect your Self-Supporting tires and use a pressure gauge to check
the inflation in all 4 tires following any low pressure warning (unless
advised to do otherwise by the manufacturer of your low pressure
warning system). If the tire pressure is at or below 18 PSI, proceed to\

the Michelin tire retailer for ZP tires (or a representative of your vehicle
manufacturer if advised to do so in your vehicle owner’s manual) and
have the tire demounted and thoroughly inspected for possible internal
damage. If you are unable to see any damage to the tire, and the tire
pressure is more than 18 PSI, reinflate your tire to the proper inflation.
When tires have cooled, check inflation again. If any tire has lost more
than 5 PSI from the previous pressure check, have the tire inspected
at once by a Michelin tire retailer (or representative of your vehicle
manufacturer if your vehicle owner’s manual so advises.) Failure to do
so may cause irreparable damage to the tire and result in sudden tire
failure and an accident.
Tire Pressure Monitoring Systems (TPMS)
Your vehicle is likely equipped with a Tire Pressure Monitoring System
(TPMS) that is designed to monitor the pressure of tires mounted on
your vehicle and sends a signal to the driver if a tire pressure falls
below a predetermined level. A TPMS should not replace monthly
manual pressure checks for all four tires and the spare. You should
manually monitor and check tire pressure inflation with a pressure
gauge. Your tires should have the recommended pressure listed by
your vehicle’s manufacturer. This information can be found in the

Unlimited Z or (Y) tires. Speed rating is identified as a part of the tire’s
sizing or service description. Exceeding the lawful speed limit is neith\
er
recommended nor endorsed.
In the latest attempt to standardize tire designations, all ratings exce\

Unlimited Z incorporate the speed symbol and load index as the tire’ s
service description.
For Example:
“Z” Rated Tires
When “Z” appears in the size description with the service descript\
ion,
the maximum speed is indicated by the service description.
Examples:
For tires having a maximum speed capability above 240 km/hr (149
mph), a “Z” may appear in the size designation.
For tires having a maximum speed capability above 300 km/hr (186
mph), a “Z” must appear in the size designation and the service
description must include Y in parenthesis. Example: 275/40ZR18
(99Y). Consult the tire manufacturer for maximum speed when there is
no service description.

is molded into the sidewall. Tires without this notation are not
recommended for winter driving in regions that experience
winter conditions.
Although All-Season tires are designed to provide reliable performance
in some winter conditions, the use of four winter tires is recommended
for optimal performance. Tires designated for use in severe winter
conditions are marked on at least one sidewall with the letters
“M” and “S” plus a pictograph of a mountain with a snowflake
on it. If such a tire needs to be temporarily replaced with a
tire not so marked, you should immediately drive at a safe
speed to a Michelin dealer to have the spare returned to the
trunk and replaced on your vehicle by another tire with the letters
“M” and “S” and the related pictograph.
Tire Rotation and Replacement
To obtain maximum tread life, you must rotate your tires. You should
rotate your tires every 6,000 to 8,000 miles (10,000 to 12,000 km)
or as specified by your vehicle manufacturer, whichever occurs
more frequently. Check your vehicle owner’s manual for any
recommendations by your vehicle manufacturer. 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. When rotating tires with a directional
tread pattern, observe the arrows molded on the sidewall that show the
direction in which the tire should rotate.
Care must be taken to maintain the proper rotation direction. Some Tire
Pressure Monitoring Systems (TPMS) may not recognize that a tire
has been moved 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 for this
information. Determine whether rotated tires require tire inflation
adjustment, because front and rear position tire pressure may vary
according to the vehicle manufacturer’s specification due to the actual
load on that wheel position. Some vehicles may have tires of different

MICHELIN
137
size mounted on the front versus the rear axles, and these different
tires have rotation restrictions. Always check the vehicle owner’s
manual for the proper rotation recommendations.
Full-Size Spare
Full-size spare tires (not temporary spares) of the same size and
construction should be used in a five-tire rotation and should be
inspected by a tire professional during routine tire inspection. Always
have spare tires inspected before installation. Tires are composed
of various types of rubber compounds and other materials having
performance properties essential to the proper functioning of the tire. \
These component properties change over time. Always check the
inflation pressure of the full-size spare and look for any indication of
cracking or other damage immediately before incorporating the spare
into rotation. If you see any damage, or if the tire is underinflated, do
not resume driving with that tire unless you have no other option, in
which case you should drive only as slowly as is safely possible in the \
traffic conditions until you can both get the spare tire properly inflated
and have it checked by a tire professional to ensure that it is safe
to use. Follow the vehicle manufacturer’s recommended pattern for
rotation. If such a recommendation is unavailable, see a qualified
tire professional.

Replacement of Two Tires
All four tires should be replaced at the same time. However, if only
two tires are replaced, the new ones should be put on the rear.
Deeper tread tires on the rear axle provide better handling, wet grip
and evacuate water, thereby helping to avoid oversteer and loss of
vehicle stability on wet surfaces. Deeper tread tires on the front axle \
can improve wet straight line braking and stopping distance. If only
two tires are being replaced, Michelin generally recommends they be
installed on the rear axle in the absence of a tire service professional’ s
recommendation or consumer’s preference to the contrary.

MICHELIN

Whenever a Repair Is Needed, Immediately See
Your Michelin
® Tire Retailer or, If One Is Not Readily
Available, Another Qualified Tire Professional
If any MICHELIN® tire sustains a puncture, have the tire demounted
and thoroughly inspected by a qualified tire professional for possible
damage that may have occurred. A tread area puncture in any
MICHELIN
® passenger or light truck tire can be repaired if the
puncture hole is not more than 1/4” in diameter, not more than one
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.
Repairs of all tires must be of the combined-plug-and-inside-patch
type. Your MICHELIN tires must be removed from the wheel for
inspection prior to repair. Plug-type repairs made on a tire that remains
mounted on a wheel are improper and can result in an accident. A tire
should be removed from the rim and inspected prior to repair. Any tire
repair done without removing the tire from the rim is improper and can
result in an accident. An improperly repaired tire may 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 and result in an accident. Never \
repair a tire with less than 2/32nds of an inch of tread remaining. At this
tread depth, the tire is worn out and must be replaced.
Storage
Tires contain materials to protect their outer surfaces from ozone
and weather checking. As the tire rolls and flexes, those materials
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

Reading the Dot
DOT XXXX XXXX XXX (prior to August 2000)
DOT XXXX XXXX XXX
(1990-1999)
DOT XXXX XXXX XXXX (after July 2000)
The Dot
The “DOT” symbol certifies tire manufacturer’s compliance with U.S.
Department of Transportation tire safety standards. Next to the symbol
is the tire identification or “serial number.” The first two characters
identify the plant where the tire was manufactured. The next two
characters reflect the tire size. The following one to four digits may
be used at the tire manufacturer’s option as a descriptive code. The
last three characters are numbers identifying the week and year of
manufacture. (Example: “O25” means second week of the year of
decade, e.g.: 1995, 1985, etc.) For the 1990-1999 decade MICHELIN
®
brand tires are marked with a triangle pointing to the last three numeri\
c
characters. Tires produced after July 2000 have an additional digit
to identify a given decade. For example, 2800 means the tire was
produced during the 28th week of 2000; 0201 during the 2nd week
of 2001. If the last digits of your DOT number contain three numeric
characters and are not marked with a triangle, consult a qualified tire
professional to determine the year of manufacture.
Service Life for Passenger Car and Light Truck Tires
Including Spare Tires
Tires are composed of various types of material and rubber
compounds having performance properties essential to the proper
functioning of the tire itself. These component properties evolve over
time. For each tire, this evolution depends upon many factors such
as weather, storage conditions, and conditions of use (load, speed,
inflation pressure, maintenance etc.) to which the tire is subjected
throughout its life. This service-related evolution varies widely so that
accurately predicting the serviceable life of any specific tire in advance
is not possible. That is why, in addition to regular inspections and
inflation pressure maintenance by consumers, it is recommended

MICHELIN
143
that passenger car and light truck tires, including spare tires be
inspected regularly by a qualified tire specialist, such as a Michelin
tire retailer, who will assess the tire’s suitability for continued service.
Tires which have been in use for 5 years or more should continue to
be inspected by a specialist at least annually. Consumers are strongly
encouraged to be aware not only of their tires’ visual condition and
inflation pressure but also of any change in dynamic performance such
as increased air loss, noise or vibration, which could be an indication \
that the tires need to be removed from service to prevent tire failure. \
It
is impossible to predict when tires should be 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 that any tires in service 10 years or more from the date
of manufacture, including spare tires, be replaced with new tires as
a precaution even if such tires appear serviceable and even if they
have not reached the legal wear limit. For tires that were on an origina\
l
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. Consumers
should locate the Department of Transportation or “DOT” code on the
tire. The code begins with “DOT” and ends with the week and year of
manufacture. For example, a DOT code ending with “2214” indicates a
tire made in the 22nd week of 2014.
