wheel size PORSCHE 911 GT3 2013 6.G Information Manual

Wheels and tyres.
Twent y inches instead of the 19 on the
predecessor model. Another improvement
to dynamic performance that brings you
closer to the sport y limit. The wheels
are platinum ­coloured and made from a
forged alloy.
The central locking device with ‘GT3’ logo
is derived from motorsport. Compared
with the conventional five ­bolt wheel con ­
nection, it offers enhanced performance
thanks to the reduction in rotating masses.
And, of course, it ensures a faster wheel
change, which is vital when you’re in the
pit and the clock is ticking. Tyre sizes are 245/35 ZR 20 on

9 J x 20 at the front and 305/30 ZR 20
on 12 J x 20 at the rear.

Road ­legal sports t yres on the new
911 GT3 help to provide the grip it
needs. Bear in mind, however, that the
reduced tread depth increases the
risk of aquaplaning on wet surfaces.
Tyre Pressure Monitoring (TPM) is fit ted
as standard in the new 911 GT3. Not only
does it send warnings to the on ­board
computer’s display screen in the event
of a gradual or sudden loss of pressure,
it also features a racetrack mode. This
takes into consideration the pressure and temperature characteristics of the t yres
on the circuit and precisely monitors
the pressure set in each individual t yre.
In other words, TPM is designed around
your sporting passion.
Porsche Active Suspension

Management (PASM).
This electronic active damping system
offers continuous adjustment of the
damping force on each wheel based on
the current driving situation and your
driving st yle.
At the press of a but ton, you can select
bet ween t wo different modes. ‘Normal’
mode is designed for sport y driving on
public roads and on wet racetracks.
‘Sport ’ mode is specially tuned for
maximum lateral acceleration and offers
the best possible traction on the track.
