Tires, Wheels
The original equipment radial tires on your
Porsche comply with all applicable Federal
Motor Vehicle Safety Standards.
Tire pressures
Check tire pressure when the tires are
still cold. Also check spare tire.
Do not drive with worn tires or tires show
ing cuts or bruises as they may lead to
sudden deflation.
For good car handling and long tire service
life, it is important to maintain recommended
tire pressures. Tires which are inflated
above or below specifications can cause in
creased tire wear, increased gas consump
tion and affect the road holding of the car.
When purchasing replacement tires, make
sure that they show the same specifications
for tire size, load carrying capacity, tread
pattern, etc. This also applies to Porsche-
recommended replacement tires.
New tires do not grip the road as well during
the first 60 to 120 miles (100 to 200 km) as
after this period. Therefore extra care should
be taken when driving with new tires.
Tire wear
If you notice that tires are wearing unevenly,
consult your authorized dealer. Uneven
wear may not always be due to improper
wheel alignment. It can be the result of indi
vidual driving habits such as cornering at
high speeds. If the tire pressure is not check
ed and adjusted regularly, abnormal tire
wear can also occur.
Tire rotation
By rotating the wheels periodically (approx.
every 3.000 miles/5.000 km), it is possible to
obtain a certain amount of uniform wear.
Only rotate wheels on the same side so that
the direction of tire rotation remains the
same.
Tire replacement
If you replace tires on one axle only, be
sure to use tires of the same make and type.
Always put the new pair of tires on the front
axle.
When replacing tubeless tires, always in
stall a new valve stem. When replacing
tires requiring an inner tube, always in
stall new tubes.
Repairs of tires and inner tubes should
be done by qualified repair shops only.
Wheels
If you intend to use other than original
equipment wheels, be sure that they con
form to Porsche specifications for your
model.
Wheel balancing
A wheel should always be balanced after a
tire repair. Also, since regular use or hard
braking can cause tire imbalance, the
wheels should be balanced from time to
time. Unbalanced wheeels may affect car
handling and tire life.
When balancing light alloy wheels, use only
adhesive balancing weights supplied
through the Porsche parts service.

Collapsible spare
ι ire pressure:
36 psi or 2.5 bar
32 psi or 2.2 bar
Do not exceed the maximum tire inflation
pressure listed on the sidewall of the tire.
All tire inflation pressures are also listed in
side the fuel filler flap. Tire pressure and
maximum speed information for the collaps
ible spare tire is located on the lid of the
spare wheel well underneath the luggage
compartment covering.
The tire pressure will increase progressively
with increasing temperature; therefore, ne
ver let any air out of warm tires to meet cold
tire pressure specifications.
In the interest of safety, check the tire pres
sure of all tires at least once a week, and
always before going on a long trip. Also,
check for unusual wear or damage such as
cuts, broken cord and punctures.
