180 Driving and Driving Safety
Despite the advantages of transmission and chassis control systems, it is still the driver’s responsibility to adapt his driving style and maneuvers in line with road and weather conditions, as well as the traffic situation.
The increased safety that is provided should not induce you to take greater risks with your safety. The limits set by the physics of driving cannot be overcome.These systems cannot reduce the risk of accidents due to inappropriate speed.fAdapt your driving style, maneuvers and speed to the road and weather conditions, as well as the traffic situation.
Porsche Traction Management
(PTM)
Porsche Traction Management is an active allwheel control system designed to influence longitudinal and lateral dynamics. It is closely linked with the Porsche Stability Management (PSM) system.
The permanently driven rear axle enhances the vehicle’s sporty features. Drive power is distributed fully variably to the front axle, depending on the driving situation.
In conjunction with PSM, the PTM system ensures perfect distribution of power among all four wheels in every driving situation. This improves traction and driving stability and ensures the same high level of agility and dynamic response.
In spite of the advantages of PTM and four-wheel drive, it is still the driver’s responsibility to adapt his driving style and maneuvers in line with road and weather conditions, as well as the traffic situation.
The increased safety that is provided should not induce you to take greater risks with your safety. The limits set by the physics of driving cannot be overcome, even with PTM or four-wheel drive.Risk of accidents due to inappropriate speed cannot be reduced by PTM or four-wheel drive.
Advantages of PTM
– Clearly perceptible improvement in traction, driving stability and steering ability of the vehicle.– Vehicle is more manageable when driven at its performance limits.– Improved straight-ahead tracking and greater stability.– More sporty vehicle setup while making full use of all the advantages of four-wheel drive.– ASR, ABD and PTV Plus further enhance traction for all wheels.
For information on ASR and ABD:fPlease see the chapter “PORSCHE STABILITY MANAGEMENT (PSM)” on page 181.
For information on current torque distribution between front and rear wheels in the multi-function display:fPlease see the chapter “ALLWHEEL MENU” on page 114.

250 Minor Repairs
Wheel alignment, wheel balancing
As a precaution, have wheels with summer tires balanced in the spring, and those with mud and snow tires before winter. Unbalanced wheels may affect car handling and tire life.Only the specified weights may be used for wheel balancing.
Self-adhesive weights must not come into contact with cleaning agents, since they could drop off.Uneven tread wear indicates wheel imbalance. In this event, the vehicle should be checked at an authorized Porsche dealer.
If, during a trip, uneven running or vibrations occur that could be caused by damage to tires or the car, the speed must be reduced immediately, but without braking sharply. If you continue your trip without having the cause of the fault remedied, you might lose control of your vehicle.fStop the vehicle and check the tires.fIf no cause for the fault can be found, drive carefully to the nearest authorized Porsche dealer.
The summer tires of your Sports Car have been specially developed and adapted for high performance. At low outside temperatures (<15°C (60°F)), the tire characteristics change. This can result in noises occurring when parking or maneuvering at low outside temperatures.
Wheels with Tire Pressure Monitoring System (TPMS) sensors
Before changing wheels, make sure that the wheels are compatible with your vehicle’s TPMS.fCheck this with your authorized Porsche dealer.
Removing and storing tires
fAfter changing, adjust tire pressure and torque wheel bolts diagonally. Please see the chapter “CHANGING WHEELS” on page 254.fStore tires in a cool and dry place. Rotate periodically to avoid flat spots.fDo not store summer tires or park vehicles fitted with summer tires at ambient temperatures below 5 °F (-15 °C).fAvoid contact with fuel, oil and grease.
Tires must always remain on the same side of the vehicle.When wheels are removed, the direction of rotation and position of each wheel should be marked.
Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with their marking.
The perception that tire durability and performance are not affected by storage and age is unfounded. Chemical additives, which make the rubber elastic, lose their effectiveness over the course of time and the rubber becomes brittle and cracks.
Therefore, the tires should be inspected from time to time.
Information
Under no circumstances should tires older than 6 years be used on your Porsche.
The age of the tire can be obtained from the “DOT” code number. If, for example, the last four numbers read 1213, then the tire was produced in the 12th week of 2013.
Snow tires
The installation of Porsche approved snow tires is recommended.
Use Porsche approved snow tires for grip on snow and ice. Summer performance tires are not suitable for usage in cold, snowy, or icy conditions.Check with your local Motor Vehicle Bureau for possible restrictions.

– third four-digit code means tire type code. – fourth four-digit code means date of manufacture.If, for example, the last four numbers read 0211, the tire was produced in the 2nd week of 2011.
C – Tire ply composition and material
The number of layers in the tread and sidewalls and their material composition.
D – Maximum permissible inflation pressure
The maximum permissible cold inflation pressure to which a tire can be inflated.fDo not exceed the permissible inflation pressure.
E – Maximum Load rating
The maximum load in kilograms and pounds can be carried by the tire. If you replace tires always use a tire that has the same maximum load rating as the factory installed tire.
F – Radial
The identification indicates if the tire has radial structure.
G – Term of tubeless or tube tire
Identification for tubeless tires.
Speed code letters
The speed code letter Y indicates the maximum permitted speed for the tire.This code letter is shown on the tire sidewall.
Information
Tires with a maximum speed rating that is lower than the specified maximum vehicle speed may be mounted only if they bear an M+S identification on the tire sidewall.fPlease note that in addition to snow tires, all-season tires are also subject to speed limits and bear this identification.fNever drive faster than the speed rating of the tires, and obey all speed and traffic laws.
G - Rim width in inches H - Rim-flange contour code letter I - Symbol for drop-center rim J - Rim diameter in inches K - Double hump L - Rim offset in mm
Inscription on alloy wheels
The information is provided on the rear of the spokes. The rim width in inches A and the rim offset F are visible from the outside. This information can be found near the tire valve.
T up to 118 mph (190 km/h)
H up to 131 mph (210 km/h)
V up to 150 mph (240 km/h)
W up to 167 mph (270 km/h)
Y up to 186 mph (300 km/h)
(Y) up to 186 mph (300 km/h) as for Y tires. Speeds of more than 185 mph(300 km/h) are also possible at a maximum tire load capacity of 85 % (confirmation from tire manufacturer required for speeds of more than 185 mph (300 km/h)).
