A Seating capacityMaximum number of vehicle occupants,

B Vehicle load limit Is the maximum total weight limit specified of
the load (passengers and cargo) for the
vehicle. This is the maximum weight of
passengers and cargo that can be loaded into
the vehicle.

Size of tires mounted at the factory.
D Recommended cold tire inflation pressure These values are for cold tires (68 °F/20 °C).
Tire traction
Warning!
When driving on wet or slushy roads, a
wedge of water may bu ild up between the
tires and the road. This phenomenon is
known as “hydroplane” and may cause
partial or complete loss of traction, vehicle
control or stopping ability.
f Reduce speed on wet surfaces to prevent this.
Tire lifeTire life depends on various factors, i.e., road
surfaces, traffic and weather conditions, driving
habits, type of tires and tire care.
f Inspect your tires for wear and damage before
driving off. If you notice uneven or substantial
wear, wheels might need alignment or tires
should be balanced or replaced.Tire wearThe original equipment tires on your Porsche have
built-in tire wear indicators. They are molded into
the bottom of the tread grooves and will appear as
approximately 1/2 in. (12 mm) bands when the
tire tread depth is down to 1/16 of an in (1.6 mm).
When the indicators appear in two or more
adjacent grooves, it is time to replace the tires.
We recommend, however, that you do not let the
tires wear down to this extent.
Worn tires cannot grip the road surface properly
and are even less effective on wet roads.
In the United States, state laws may govern the
minimum tread depth permissible. Follow all such
laws.

Minor Repairs
Danger!
Driving on worn tires can result in loss of
control of the vehicle and could cause
serious personal injuries or death.
f Do not drive with worn tires or tires showing
cuts or bruises as they may lead to sudden
deflation and loss of control which could cause severe personal injury.
f If you notice that tires are wearing unevenly,
consult your authorized Porsche dealer.
Uneven wear may not alwa ys be due to improper
wheel alignment. It can be the result of individual
driving habits such as cornering at high speeds. If
the tire pressure is no t checked and adjusted
regularly, abnormal tire wear can also occur.
Tire caref Avoid damaging tires and wheel rims.
f I f y o u m u s t d r i v e o v e r a c u r b o r o t h e r o b s t a c l e ,
drive slowly and at an obtuse angle.
f Check tires for uneven wear and damage
before driving off.
f Remove imbedded material.
f Replace worn or damaged tires immediately.
f Keep oil, fuel, brake fluid, etc. away from tires.
f Replace missing valve stem caps.
f Keep tires inflated correctly.
f Wash tires when washing the vehicle. Also
clean inner side of wheels.
f Do not use abrasive cleaners when washing
the wheels.
f Check wheel rims for corrosion.
f Remove road salt, if driving in winter.
Tire damage, puncturefPlease see the chapter “HIGH-PRESSURE
CLEANING EQUIPMENT” on page 270.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected
tires.
f Check tires – including sidewalls – regularly for
foreign bodies, nicks, cuts, cracks and bulges.
f Cross curb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp curbs.
f In cases of doubt, have the wheel (particularly
the inner side) checked by an authorized Porsche dealer.

Minor Repairs

In case of tire damage, where it is uncertain
whether there is a break in the ply with all its
consequences or tire damage caused by thermal
or mechanical overloading due to loss of pressure
or any other prior damage, we recommend that
the tire be replaced for safety reasons.
If one faulty tire is replac ed it should be noted that
the difference in tread depth on one axle must not
exceed 30%. Handling inconsistencies may result.
f Perform a visual inspection if necessary.Tire replacementsfUse only tire makes and types tested by
Porsche.
If you do not use a Porsche recommended
replacement tire, make sure that you
purchase your new tires from a reputable tire
dealer and that the dealer complies with all
manufacturers warnings for those tires.
Only tires with the same manufacturer and
with the same specific ation code (e.g. “N0”,
“N1”…) should be mounted on the vehicle.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Tires should be replaced no less than on one axle
at the time. Only tires of the same make and type
must be used. Mixed tire s are not permissible and
will affect vehicle performance, safety, and can
affect vehicle warranty. Porsche dealers can recommend the most current
replacement tire options for your vehicle.
Initially, new tires do not have their full traction.
You should therefore drive at moderate speeds
during the first 60 - 120 miles (100 - 200 km).
Tires must always remain
on the same side of
the vehicle.
When wheels are removed, the direction of
rotation and position of each wheel should be
marked.
If new tires are installed only on one axle, a
noticeable change in hand ling occurs due to the
different tread depth of the other tires. This
happens especially if only rear tires are replaced.
However, this condition disappears as the new
tires are broken in.
f Please adjust your driving style accordingly.
Installation of new tires should only be done by a
qualified tire technician.
Valves
f Use only plastic valve caps.
f The rubber valves must be replaced whenever
the tires are changed.
f The fitting and replacement specifications
must be observed for metal valves.
f Only use Original Porsche metal valves.
f Protect the valve inserts against soiling with
valve caps. Soiled valve inserts can cause a
gradual loss of air.
Parking at the curb
Danger!
Hard impacts against curbs (or traffic
islands) are dangerous and may cause
hidden tire damage which is not noticeable
until later. Such damage can result in
accidents at high speeds causing serious
personal injury or death. Depending on the
force of impact, the edge of the rim can also
be damaged.
f After such an impact, have the wheel checked
by an expert.
f If you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle. Exercise care when parking along curbs.
Maintenance note
Tire repairs are not permissible under any
circumstances.
Wheel alignment, wheel balancingAs a precaution, have wheels with summer tires
balanced in the spring, and those with mud and
snow tires before winter. Unbalanced wheels may
affect car handling and tire life.
Only the specified weights may be used for wheel
balancing.
