SELF-SUPPORTING ZERO PRESSURE
(ZP) TIRES
AT LOW OR ZERO AIR PRESSURE
The handling characteristics of a vehicle with a deated Self-Supporting Zero
Pressure (ZP) tire (whether front or rear) are not the same as those of a vehicle
with normally inated 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 underinated 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 ination will depend on the severity 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 ination. Continuous use of an
underinated tire may lead to sudden tire failure and an accident. If a tire at low
or zero pressure begins to vibrate or cause difculty 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 - Modied) 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 ination
pressures must be maintained as a minimum. Never exceed the Maximum
Pressure rating shown on the tire sidewall.
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 ination 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
