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)
Check cold pressure as soon as possible, preferably within 24 hours.
“Bleeding” air from hot tires could result in underinflation. Use an
accurate tire gauge to check pressures. Never allow children to inflate
or deflate tires.
FOR MICHELIN® PAX® SYSTEM TIRES/SELF-SUPPORTING ZERO
PRESSURE (ZP) TIRES CHECK INFLATION PRESSURES AS SOON
AS POSSIBLE FOLLOWING A LOW PRESSURE WARNING
The PAX® System requires a functioning, correctly calibrated on-board
vehicle tire pressure 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 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
air pressure 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 MICHELIN® PAX® System tire and
self-supporting tires and use a pressure gauge to check the air pressure
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 nearest
Authorized PAX System Retailer 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 pressures when tires are hot.) When tires
have cooled, check air pressure again. If any tire has lost more than
MICHELIN170
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 (4) tires and the spare. We recommend that
you 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 vehicle
owner ’s manual and often on a placard located in the vehicle’s door
jamb, inside the fuel hatch, or on the glove compartment door. If you
have a plus size fitment that requires a higher inflation pressure, your tire
pressure monitoring system will require re-calibration to new inflation
pressure. Refer to your tire dealer/installer of plus size tires for proper
inflation pressure.
We recommend checking air pressure once each month, and before a long
trip. Whether you have a full-sized or mini-spare, make sure that it is
properly inflated as well. If the TPMS generates improper monitoring or
signals we recommend that you consult your owner ’s manual provided
with your vehicle and follow-up with your vehicle’s manufacturer.
TIRE SPINNING
Do not spin wheels in excess of 35 mph (55 km/h) as indicated on the
speedometer. Excessive speed in a free-running, unloaded tire can cause
it to “explode” from centrifugal force. The energy released by such an
explosion is sufficient to cause serious physical injury or death. Never
allow anyone to stand near or behind the spinning tire.
When in mud, sand, snow, ice or other slippery conditions, do not engage
in excessive wheel spin. Accelerating the motor excessively, particularly
with automatic transmission vehicles, may cause a drive tire that has lost
traction to spin beyond its speed capability. This is also true when
balancing a drive tire/wheel assembly on the vehicle using the vehicle
engine to spin the tire/wheel assembly.
MICHELIN
171
When rotating tires with a directional tread pattern, observe the arrows
molded on the sidewall which show the direction the tire should turn.
Care must be taken to maintain the proper turning direction.
Some Tire Pressure Monitoring Systems (TPMS) may not recognize
that a tire has been moved to a different position on your vehicle. Make
certain that your TPMS system is reset, if necessary, so as to correctly
identify the location of each tire on your vehicle. Refer to your vehicle
owner ’s manual or your vehicle dealer.
Determine whether rotated tires require tire inflation adjustment as front
and rear position tire pressure may vary according to the vehicle
manufacturer ’s specification due to the actual load on that wheel
position. Some vehicles may have different sized tires mounted on the
front and rear axles, and these different sized tires have rotation
restrictions. Always check the vehicle owner ’s manual for the proper
rotation recommendations.
Full-size Spare
Full-size spare tires (not temporary spares) of the same size and construc-
tion should be used in a five (5) tire rotation. Always check the inflation
pressure of the full-size spare immediately before incorporating it into
rotation. Follow the vehicle manufacturer ’s recommended pattern for
rotation, or if not available, see a qualified tire technician.
Replacement of Two (2) Tires
It is recommended that all four (4) tires are replaced at the same time.
However, when only two tires are replaced, the new tires should be put
on the rear. The new tires, with deeper tread, may provide better grip and
water evacuation in wet driving conditions.
CUSTOMIZATION OF TIRES, WHEELS, OR SUSPENSION ON
SUVS AND LIGHT TRUCKS
Due to their size, weight and higher center of gravity, vehicles such as
SUVs and light trucks do not have the same handling characteristics as
automobiles. Because of these differing characteristics, failure to operate
your SUV/truck in a proper and safe manner can increase the likelihood
of vehicle rollover. Modifications to your SUV/truck tire size, tire type,
wheels or suspension can change its handling characteristics and further
increase the likelihood of vehicle rollover. Whether your SUV/truck has
the original equipment configuration for tires, wheels and suspension or
whether any of these items have been modified, always drive safely,
