owner’s manual, vehicle manufacturer, or a Bridgestone

TPMS operation and service.
RUN-FLAT or LOW TIRE PRESSURE
OPERATION
SAFETY WARNING
Serious personal injury or death may result from a tire failure or
accident due to improper run-flat or low tire pressure operation.
Read and follow the instructions below, and the other mainte-
nance and safety recommendations elsewhere in this manual.
General Instructions
The Tire Pressure Monitoring System (TPMS) required in your
vehicle may have different methods of alerting you when your
tire has lost inflation pressure. The international standard for the
definition of run-flat operation is pressure at or below 10 psi (70
kPa); however, some vehicle manufacturers may have estab-
lished a different pressure limit. Consult your vehicle owner’s
manual for the details of your TPMS. Once the TPMS has indi-
cated that a tire has reduced inflation pressure, the run-flat mode
of operation has commenced. During this phase of operation,
please follow these instructions:
• Reduce speed as much as safely and reasonably possible;
do not exceed 50 mph (80 km/h). The greater the speed,
the less distance the tire can travel.
• Avoid abrupt or aggressive acceleration, braking, or
cornering maneuvers as much as safely and reasonably
possible. Pot holes and other road hazards should be
avoided. Careful driving limits potential damage to the tire,
wheel, and vehicle.
• Proceed to a safe and convenient location for tire service
as soon as possible. Take note of your mileage; your
operation distance is limited. See "Distance—How Far You
Can Drive,” the next section in this manual.
• If an unusual vibration or vehicle handling difficulty arises,
stop driving as soon as safely and reasonably possible.
The tire may be about to suddenly fail. Release the accelera-
tor and gradually reduce speed. The tire will need to be
replaced before proceeding.
• If towing a trailer, stop driving as soon as safely and
reasonably possible. In this condition, it is potentially
dangerous to operate a vehicle/trailer combination. If
possible, disconnect the trailer and proceed as noted above.
Do not continue to tow any trailer until proper tire service or
replacement has been performed.
• Do not touch a tire recently run-low or run-flat (it may be
very hot). Allow the tire to cool before handling.
