Wheels and Tires

It allows conclusions to be drawn regarding the level
of grip and the rigidity of the tires.
Information
The tire temperature is calculated based on several
variables (e.g. acceleration, wheel speed, ambient
temperature, etc.). The tire temperature display
shows a mean value of the temperatures of the tire
tread surface, the belt core and the interior of the
tire. It is therefore not possible to measure the dis-
played tire temperature at any specific point of the
tire.
Display
The tire temperature is displayed as a colored bar
next to the tire pressure (actual pressure) for each
wheel on the instrument cluster.
A cold tire is indicated by a blue bar. During the
transition period, the color of the bar changes from
blue to white. When the tire is at operating temper-
ature, the bar is white. The larger the bar appears,
the warmer the tire is.

Information
The summer and UHP tires approved by Porsche
ensure safe vehicle handling over a wide tempera-
ture range, including with cold tires.
e
Adapt your driving style and maneuvers to the
road and weather conditions and to the traffic
situation.
e Bring the tires to operating temperature for driv-
ing with the maximum dynamics experience or
for driving on racetracks.
Setting the Tire Pressure Monitor-
ing System (TPMS) in the PCM
WARNING
Incorrect settings
Tire pressure that is too low or too high destroys the
tire and wheel, extends the braking distance and
significantly increases the risk of an accident.
Although the Tire Pressure Monitoring System is
available, it is the driver's responsibility to ensure
that the tires are inflated to the correct tire pressure
and that the vehicle settings are correct. Incomplete
or incorrect settings can affect the output of warn-
ings and notices.
e
Adjust tire pressure to suit your tires and the
load.
e Ensure that the settings in the TPMS menu cor-
respond to the tires fitted on the vehicle and the
current load of the vehicle (especially after a
wheel change or changes in vehicle loading).
e Select tire type and size in the Tire Pressure
Monitoring menu again, even if a newly mounted
wheel set corresponds to the settings of the
predecessor.

Pressure deviation
The required pressure, the pressure difference from
the required pressure at the relevant wheel as well
as the setting for load, tire type and size are
displayed.
Example: If the reading for the right rear tire is
shown as –0.1 bar , this tire needs to be inflated by
1.4 psi (0.1 bar). The tire temperature has already
been taken into account in the pressures shown.
e
You should only use the pressure difference from
the display or the corresponding tire pressure
warning to correct the tire pressure.
In the case of tires that have not yet been taught-in,
the new target pressures are displayed instead of
the actual pressure differences.
Setting the tire type and tire size
Information
The options available depend on the model and tire
type. It is therefore possible that not all the options
shown here are available.
e
Before fitting tires and wheels with dimensions
that are not available for selection in the Tire
Pressure Monitoring System menu, the missing
information should be added. Visit an authorized
Porsche dealer. Porsche recommends an author-
ized Porsche dealer, as they have trained techni-
cians and the necessary parts and tools.
e Only use tires and wheels approved by Porsche.
