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.

Filling in tire sealant
The tire sealant can be found in the right-hand box in the luggage compartment. The compressor is located under the cover in the luggage compartment.
The tire sealant can be used to seal small cuts, especially in the tire tread.
Sealing the tire with the tire sealant is only an emergency solution so you can drive to the nearest workshop. Even if the tire is air-tight, it may only be used for short journeys in an emergency.
The tire sealant set comprises: – a filler bottle– a filler hose– a valve turner– a spare valve insert– a sticker with the maximum permitted speed– a compressor– operating instructions
Always observe the following points:fUse the tire sealant only in the case of cuts or punctures no larger than 0.15 in. (4 mm).fNever use the tire sealant if the rim is damaged.
The sealant is highly flammable and harmful to health.fFire, naked flame and smoking are prohibited when handling tire sealant.fAvoid contact with skin, eyes or clothing due to caustic chemical properties of the tire sealant.fKeep tire sealant away from children.fDo not inhale vapors, due to the consequent harm to personal health resulting in serious personal injury or death.
In the event of contact with sealant:
fIf sealant gets on your skin or into your eyes, thoroughly rinse the affected part of your body immediately with plenty of water.fChange soiled clothing immediately.fSee a doctor immediately in the event of an allergic reaction.fIf sealant is swallowed, thoroughly rinse out the mouth without delay and drink plenty of water. Do not induce vomiting.See a doctor immediately.
