Tire pressures
Measure tire pressure only when tires are cold. Air pressure increases as tires get hotter and must not be decreased.
Collapsible spare wheel:
2.2 bar (32 psi)
Note
Underinflation can cause tire damage that is not immediately noticeable.
Conditions leading to slow air loss or structural damage
^
damage to bead during installation
^
installation damage from excessive expansion of bead core; tire could part from rim
^
installation damage to inside of tire; could cause loss of air or ply separation
^
punctures from foreign objects (nails, glass, rocks, etc.); moisture can cause rust at puncture
^
squeezing damage (from driving over potholes, curbs, or similar objects)
^
sidewall damage (from rubbing against curb or slipping off road shoulders)
^
cuts in tire (especially sidewalls)
^
damage from underinflation
CAUTION
Porsche recommends replacing a tire if there is damage to the tread or sidewall and any possibility of structural deterioration exists.
Note
Repairing tires with pressurized sealants or tubes is not acceptable.
Retreading tires is not acceptable.
Wear
Excessive, rapid tire wear is usually attributed to driving habits.
Almost all tires have tread wear indicators specified for the U.S.
The tread wear indicator is a ridge across the tread base at 6 points on the circumference of the tire.
