DRIVING ON ANY TIRE THAT DOES NOT HAVE THE CORRECT INFLATION PRESSURE
IS DANGEROUS
Any underinflated tire builds up excessive heat that may result in sudden 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. However, do not exceed
th
e maximum pressure rating indicated on the tire sidewall.
CHECK THE COLD INFLATION PRESSURE IN ALL YOUR TIRES, INCLUDING THE SPARE, AT
LE A
ST ONCE EACH MONTH
Failure to maintain correct inflation may result in improper vehicle handling and may
c a
use 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 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 simply 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, before they have been
d r
iven 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 three minutes or
m o
re than 1 mile, (1.6 km) the tires become hot and the pressures will increase by
a p
proximately 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.
Check cold pressure as soon as possible, preferably within 24 hours. “Bleeding” air from
h o
t tires could result in underinflation. Use an accurate tire gauge to check pressures.
Never allow children to inflate or deflate tires. 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)

ECK INFLATION PRESSURES AS SOON AS POSSIBLE FOLLOWING A LOW PRESSURE
WARNING
The PAX® System requires a functioning, correctly calibrated on-board vehicle tire
p r
essure 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 low air pressure
s i
tuation 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 self-supporting tires and
u s
e 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 Authorized PAX® System
R e
tailer 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 instructions for checking
p r
essures 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 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. We recommend that you
manually monitor and check tire pressure inflation with a pressure gauge. Your tires
