Information
If a tire is damaged and it is not possible to determine with absolute certainty that there is no ply damage
- with all of its consequences - or if the tire was thermally and/or mechanically overloaded due to a loss of
pressure or other prior damage, replace the tire in question for safety reasons.
Repairs to "V", "W", "Y" and "ZR" tires are not permissable, as well as the use of inner tubes in tubeless
tires. Please inform your customers accordingly. It is advisable to mount winter tires at temperatures
below 45° F/7°C , because the driving characteristics of summer tires are reduced at low temperatures.
Extremely low temperatures can cause permanent damage to summer tires.
WARNING
Incorrect tire pressure
•
Uncontrollable vehicle handling
Adjust the tire pressure according to specifications. Never allow the pressure to fall below the minimum
pressure.
Check age of tires. Replace tires that are more than 6 years old.
Perform visual inspections.
Use new rubber valves at every tire change.
Use only tires approved by Porsche.
Tire Pressure:
16/17/18-inch wheels
Emergency spare wheel
Front axle
2.0 bar (29 psi)
4.2 bar (61 psi)
Rear axle

Information
The tire pressure applies only to the tire makes and types approved by Porsche, and is specified for cold
tires (approx. 68° F/20°C ). The tire pressures must never be lower than the specified values.
