vehicle owner’s manual and is on a placard located in the vehicle’s
door jamb, inside the fuel hatch, or on the glove compartment door. If
you have plus-size tires that require a higher inflation pressure, your
tire pressure monitoring system will require re-calibration to the new
proper inflation pressure. Refer to your tire dealer/installer of plus-size
tires for proper inflation pressure. You should check air pressure in all
your tires, including the spare, once each month and before every long
trip. Regardless whether your spare is a full-size spare or a mini-spare,
make sure that it is properly inflated. If the TPMS generates improper
monitoring or signals, you should consult your vehicle owner’s manual
and follow up with your vehicle’s manufacturer.
TIRE SPINNING
Do not spin wheels at more than 35 mph (55 km/hr) as indicated
on your vehicle’s speedometer. Excessive speed in a free-running,
unloaded tire can cause it to “explode” from centrifugal force. The
energy released by such an explosion may cause serious physical
injury or death. Never allow anyone to stand near or behind a spinning
tire. When in mud, sand, snow, ice, or another slippery condition,
do not engage in excessive wheel spin. Accelerating the motor
excessively, particularly with automatic transmission vehicles, may
cause a drive tire that has lost traction to spin beyond its speed-
enduring capability. This is also true when balancing a drive tire/wheel
assembly on the vehicle using the vehicle engine to spin the
tire/wheel assembly.
High Speed Driving Is Dangerous
Correct inflation pressure is especially important. However, at high
speeds, even with the correct inflation pressure, a road hazard is more
difficult to avoid, and if tire contact is made with it, there is a greater
chance of causing tire damage than at a lower speed. Moreover,
driving at high speed reduces the reaction time available to avoid
accidents and bring your vehicle to a safe stop.
MICHELIN

Exceeding the maximum speeds shown on the following page for each
type of MICHELIN® tire will cause the tire to build up excessive heat,
which can cause tire damage that could result in sudden tire failure
and rapid air loss. Failure to control a vehicle when one or more tires \
experience a rapid air loss can lead to an accident.
In any case, you should not exceed reasonable speeds as indicated by
the legal limits and driving conditions.
Speed Rating System
The speed rating of a tire indicates the
speed category (or range of v speeds)
at which the tire can carry a load under
specified service conditions. The speed
rating system used today was developed
in Europe in response to the need to
categorize tires into standardized speeds.
A letter from A to Z symbolizes a tire’s
certified speed rating, ranging from 5 km/
hr (3 mph) to above 300 km/ hr (186
mph). This rating system (see chart on
this page) describes the top speed for
which a tire is certified.
When this speed rating system was originally developed, the
Unlimited V category of over 210 km/hr (130 mph) was the top speed
rating a tire could achieve. As manufacturers made more tires that fit
into this category, it was necessary to better regulate performance at
standardized speeds to help ensure safety. The Limited V category of
240 km/hr (149 mph) was then created, and the Z or (Y) speed rating
was added as the top speed rating that a tire could achieve. W and Y
limited speed symbols have been added as higher speed categories.
Always consult the tire manufacturer for the maximum speed of
MICHELIN
131
Consult your Michelin tire retailer for maximum speed capabilities.
Although a tire may be speed-rated, no vehicle should be operated in
an unsafe or unlawful manner. Speed ratings are based on laboratory
tests that relate to performance on the road, but are not applicable
if tires are underinflated, overloaded, worn out, damaged, altered,
improperly repaired, or retreaded. 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
the sidewall have a maximum speed rating of 105 mph (170 kph). Light
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 kph). Michelin
winter tires that do not have a speed symbol on the sidewall or tires
with Q symbols have a speed rating of 100 mph (160 km/hr). Winter
tires with a speed symbol have a maximum speed rating in accordance
with the symbol. The speed and other ratings of retreaded tires are
assigned by the retreader and replace the original manufacturer’s
ratings. IMPORTANT: The replacement tire speed rating should be
equal to or higher than the OEM tire speed rating. If a lower speed
rated tire is selected, then the vehicle top speed becomes limited
to that of the lower speed rating selected. The customer must be
informed of the new speed restriction and that the vehicle’s handling
may be adversely impacted. REMEMBER…High speed driving can
be dangerous and may damage your tires. AND…When driving at
highway speeds, correct inflation pressure is especially important.
Inspect Your Tires, And Do Not Drive On A Damaged
Tire Or Wheel
Road hazards and objects in the road, such as potholes, curbs, glass,
metal, rocks, wood, and debris, can damage a tire and should be
safely avoided. If your vehicle hits any such hazard or object, however,
you should promptly inspect your tires. If you see any damage to any

have safety humps or ledges. Always utilize valve caps capable of
containing the tire’s inflation, should the valve core leak. The valve
cap is the primary seal against air loss. Each tire and wheel assembly
should be balanced to ensure proper tire and vehicle performance and
to maintain tire warranty coverage. Tires and wheel assemblies that
are not balanced may cause steering difficulties, a bumpy ride, and
irregular tire wear.
Special Mounting Instructions For Self-Supporting
Zero Pressure™ (ZP) Tires
ZP tires can be more difficult to mount than conventional tires. They
should be mounted and 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 OR DEATH. Michelin
® ZP tires are
tubeless tires designed to operate in emergency conditions at low or
zero air inflation.
MICHELIN® Self Supporting Zero Pressure™ (Zp) Tires
and Special Sh-M (Symmetric Hump-Modified) Wheels
Some MICHELIN® ZP tires can perform with zero pressure capability
only when mounted on special SH-M wheels. These tires bear the
SH-M designation immediately following the ZP designation on the
sidewall of the tire.
Temporary Type Spare Tires
When using any temporary type spare tire, be sure to follow the vehicle \
manufacturer’s instructions.

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.
