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
