Spare wheel
Warning!
Risk of accident. The wheel and tire size and
the tire quality of the spare wheel and normal
wheel may differ.
If a spare wheel that differs from the normal
tires is used, this may impair the driving
behavior.
f The spare wheel must be used only over short
distances in cases of emergency.
For safety reasons, replace the tires before
the wear indicators appear (webs in the tire
grooves, 1/16 in. (1.6 mm) high).
f Never deactivate the Porsche Stability
Management (PSM) system.
f If the tire on the spare wheel is older than
4 years, the spare wheel should be used only
in the event of a flat.
f Avoid hard acceleration and high cornering
speeds.
The maximum permitted speed is 50 mph
(80 km/h) if the mounted spare wheel differs
from the other three wheels on the car. This
maximum speed must not be exceeded
because of altered driving characteristics and
for reasons of wear.
f Do not use a spare wheel from a different
vehicle type.
f Do not mount the spare wheel from your car on
a different vehicle.
