Tires, Wheels
The original equipment radial tires on your
Porsche c o m p l y w i t h all applicable Federal
M o t o r Vehicle Safety Standards.
Tire pressures
Check tire pressure when the tires are still
cold. Also check spare tire.
Tire pressure:
36 psi or 2.5 bar
Tire size:
225/50 VR 16
215/60 VR 15
205/55 R 1 6 M + S
185/70 SR 15 M + S
Collapsible spare 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 f l a p . 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 c o v e r i n g .
The tire pressure will increase p r o g r e s s i v e l y
with increasing temperature; therefore, never
let any air out of w a r m tires to meet c o l d 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 t r i p . Also,
check for unusual wear or damage such as
cuts, broken c o r d and punctures.
Do not drive with w o r n tires or tires show-
ing cuts or bruises as they may lead to
sudden deflation.
For g o o d 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 increased
tire wear, increased gas consumption 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 p e r i o d . Therefore extra care should
be taken when driving with new tires.
Tire wear
If you notice that tires are wearing un-
evenly, consult your authorized dealer. U n -
even w e a r may not always be due to im-
proper wheel alignment. It can be the result
of individual driving habits such as corner-
ing at high speeds. If the tire pressure is
not checked and adjusted regularly, ab-
normal tire wear can also occur.
Tire rotation
By rotating the wheels periodically (approx,
e v e r y 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
f r o n t axle.
When replacing tubeless tires, always install
a new valve stem. When replacing tires re-
quiring an inner tube, always install 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 w h e e l s , be sure that they c o n -
form to Porsche specifications for your
model.
Wheel balancing
A w h e e l 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. U n -
balanced wheels may affect car handling and
tire life.
W h e n balancing light alloy wheels, use only
adhesive balancing w e i g h t s supplied through
the Porsche parts service.
