(Continued)
• Use an accurate tire gauge to check tire air pressures. Always
maintain the proper recommended air inflation pressure in all
tires. If there is an indication that one of your tires has lost four
or more pounds of air pressure, immediately look for signs of
penetration through the tire, valve leaks or wheel damage that
may account for the air loss. You should also have your tires
inspected by a tire retailer immediately.
• Air pressure should be checked when tires are cold (before they
h
ave been driven), ideally in the early morning. Driving, regard -
less of distance, causes tires to heat up and simultaneously
in
crease air pressure.
• Never exceed the maximum inflation pressure for the tire.
•
Never bleed air from hot tires as this may result in underinfla -
t
ion.
• Inspect your tires daily. If you notice any damage to your tires or
w
heels, replace them with a spare and immediately visit any tire
retailer for advice. Driving over potholes, curbs, wood debris,
metal, etc., can damage a tire and should be safely avoided.
Contact with such hazards requires an immediate and thorough
tire inspection by your tire retailer.
• Always examine your tires for penetrations, bulges, cracks, cuts,
a
nd abnormal wear – particularly at the tire edges – which may
be caused by, for example, vehicle misalignment or tire underin -
flation. Failure to properly control a vehicle when one or more
ti
res are underinflated may result in an accident. Use of a
damaged tire may result in rapid air loss, including sudden tire
failure.
• An explosion of the tire/rim assembly may occur due to improper
m
ounting. Only specially trained persons should mount tires.
• Failure to store tires in accordance with the following recom -
m
endations may result in damage to your tires, reduction in tire
du
rability, or sudden tire failure.

CONTROLLABILITY
Controlling a vehicle when a tire failure occurs
If a tire failure occurs, you may hear a loud noise, feel a vibration,
an
d/or the vehicle may pull toward the side of the failed tire. If
possible, step on the accelerator momentarily to maintain forward
momentum and ensure vehicle control. It is most important that you
DO NOT BRAKE OR ABRUPTLY TURN THE STEERING WHEEL.
Slowly remove your foot from the accelerator and hold the steering
wheel firmly while steering to remain in your lane. Once the vehicle
has slowed and is fully under control, apply the brakes gently; safely
pull over to the shoulder and come to a stop. Inspect the tires. If one
or more looks flat or low, shows detachment or other damage, remove
tire assembly and replace it with a properly inflated spare. Bumps or
bulges may indicate detachment within the tire body and require
inspection by a qualified tire technician.
DRIVING ON ANY TIRE THAT DOES NOT HAVE THE CORRECT
I N

FLATION PRESSURE IS DANGEROUS
Any underinflated tire builds up excessive heat that may result in
su
dden tire destruction. If tires are supplied as original equipment,
refer to the tire decal on the vehicle (check vehicle and/or vehicle
Owner’s Manual for decal location) for the recommended operating
pressures. For replacement tires, the correct inflation pressure will be
provided by your tire retailer; if not, refer to the vehicle decal.
These inflation pressures must be maintained as a minimum.
Ho
wever, do not exceed the maximum pressure rating indicated on
the tire sidewall.
SELF-SUPPORTING TIRES. ZERO PRESSURE (ZP) TIRES, AND
PA
X® SYSTEM TIRES, AT LOW OR ZERO AIR PRESSURE
The handling characteristics of a vehicle with a deflated PAX® System
ti
re or 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.

all provisions of the limited warranty are void. For a list of approved
systems, see an authorized PAX® System retailer, or call toll free:
1-877-PAX TIRE or 1-877-729-8473
For all types of tires, consult your vehicle tire placard or owner’s
ma
nual for recommended operating pressures. If the tires are
purchased as replacement tires, operating instructions for the low
pressure warning system will be provided by the manufacturer of that
system. Recommended operating pressures will be provided by a
participating Michelin® tire retailer for self supporting ZP tires.
Recommended operating pressure for PAX® System Tires will be
provided by a PAX System retailer. These inflation pressures must be
maintained as a minimum. However, do not exceed the maximum
pressure rating indicated on the tire sidewall.
CHECK THE COLD INFLATION PRESSURES IN ALL YOUR
T I

RES, INCLUDING THE SPARE, AT LEAST ONCE EACH
MONTH
Failure to maintain correct inflation may result in improper vehicle
ha
ndling and may cause rapid and irregular tire wear, sudden tire
destruction, loss of vehicle control and serious personal injury.
Therefore, inflation pressures should be checked at least once each
month and always prior to long distance trips. This applies to all tires,
including sealant types, and Self-Supporting Zero Pressure (ZP) tires
which are as susceptible to losing air pressure as any other type of tire
if not properly maintained.
UNDERINFLATION
It is impossible to determine whether tires are properly inflated by
si
mply looking at them. It is almost impossible to “feel or hear” when
a tire is being run underinflated or nearly flat. Tires must be checked
monthly with a tire pressure gauge.
Pressures should be checked when tires are cold, in other words,
be
fore they have been driven on. Driving, even for a short distance,
causes tires to heat up and air pressure to increase.
Checking pressure when tires are hot:
If pressures are checked after tires have been driven for more than
th
ree minutes or more than one mile, (2 km) the tires become hot and
th

e pressures will increase by approximately 4 psi. Therefore when the
tire pressure is adjusted under these conditions, it should be increased
to a gauge reading of 4 psi greater than the recommended cold
inflation pressure.

MICHELIN®
166
For Example Only:
• Gauge reading of hot tire:.............................................. 32 psi (220 kPa)
•
If recommended cold inflation pressure is: ................ 30 psi (205 kPa)

•
Desired gauge reading of hot tire 30 + 4 psi =... 34 psi (205 + 30 = 235 kPa)

•
Therefore: add 2 psi.................................................................... (15 kPa)
C
heck cold pressure as soon as possible, preferably within 24 hours.
“B
leeding” air from hot tires could result in underinflation. Use an
accurate tire gauge to check pressures. Never allow children to
inflate or deflate tires.
FOR MICHELIN® PAX® SYSTEM TIRES/SELF-SUPPORTING
ZE
RO PRESSURE (ZP) TIRES CHECK INFLATION PRESSURES
AS SOON AS POSSIBLE FOLLOWING A LOW PRESSURE
WARNING
The PAX® System requires a functioning, correctly calibrated
on
-board vehicle tire pressure monitoring system (TPMS) to
monitor the air pressure and alert the driver when a low pressure
event occurs. Be certain to ensure that your vehicle’s 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
lo
w air pressure 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 MICHELIN® PAX® System tire and
se
lf-supporting tires and use a pressure gauge to check the air
pressure in all four 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 nearest
Au
thorized PAX® System Retailer for PAX® tires or a participating
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 air pressure. See

MICHELIN®
167
instructions for checking pressures when tires are hot. When tires
have cooled, check air pressure again. If any tire has lost more than
5 PSI from the previous pressure check, have the tire inspected at
once by an authorized PAX® System Retailer for PAX® tires or a
participating 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 destruction and personal injury.
TIRE PRESSURE MONITORING SYSTEMS (TPMS):
Your vehicle may be equipped with a Tire Pressure Monitoring
Sy
stem (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. We recommend that you 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 vehicle Owner’s Manual and often on
a placard located in the vehicle’s door jamb, inside the fuel hatch, or
on the glove compartment door. If you have a plus size fitment that
requires a higher inflation pressure, your tire pressure monitoring
system will require re-calibration to new inflation pressure. Refer to
your tire dealer/installer of plus size tires for proper inflation
pressure.
We recommend checking air pressure once each month, and before a
l o

ng trip. Whether you have a full-sized or mini-spare, make sure that
it is properly inflated as well. If the TPMS generates improper
monitoring or signals we recommend that you consult your Owner’s
Manual provided with your vehicle and follow-up with your vehicle’s
manufacturer.
TIRE SPINNING
Do not spin wheels in excess of 35 mph (55 km/h) as indicated on the
sp

eedometer. Excessive speed in a free-running, unloaded tire can
cause it to “explode” from centrifugal force. The energy released by
such an explosion is sufficient to cause serious physical injury or
death. Never allow anyone to stand near or behind the spinning tire.
When in mud, sand, snow, ice or other slippery conditions, do not
en
gage in excessive wheel spin. Accelerating the motor excessively,
particularly with automatic transmission vehicles, may cause a drive

MICHELIN®
168
tire that has lost traction to spin beyond its speed 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 CAN BE DANGEROUS
Correct inflation pressure is especially important. H
owever, at high
speeds, even with the correct inflation pressure, a road hazard, for
example is more difficult to avoid and if contact is made, has 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. If you see any damage
to a tire or wheel, replace it with the spare at once and visit a
participating Michelin® tire retailer.
Exceeding the maximum speeds shown on the following page for each
ty
pe of Michelin® tire will cause the tire to build up excessive heat
which can cause tire damage that could result in sudden tire
destruction and rapid air loss. Failure to control a vehicle when one or
more tires experience a sudden 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 RATINGS
Speed Symbols are shown on the sidewall of some Michelin® tires.
Th
e following table shows the maximum speed corresponding to the
symbol.
*Some V (or VR) rated tires may have a speed capacity greater than
14
9 mph (240 km/h). Consult your participating Michelin® tire
re

tailer for maximum speed rating if your vehicle capability exceeds
this speed.
**Z (or ZR) rated tires are designed to use on cars with maximum
sp
eed capabilities in excess of 149 mph (240 km/h).
(W and Y speed ratings are subcategories of Z).
Consult your Michelin® tire retailer for maximum speed capabilities.
Fo
r PAX® System Tires consult an authorized PAX® System Tire
Retailer. Although a tire may be speed-rated, we do not endorse the
operation of any vehicle in an unsafe or unlawful manner. Speed
ratings are based on laboratory tests which relate to performance on
the road, but are not applicable if tires are underinflated, overloaded,
worn out, damaged, altered, improperly repaired or retreaded.

MICHELIN®
169
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.
