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
