Tire condition
I tire pressure
Tires are safely-relevant
items that are only capable of meeting the requirements
applicable
if they
are run at the correct tire pressure and with sufficient tread depth.
The tire pressures indicated are minimum pressures. The tires must never be run at lower pressures
since this affects roadholding
In a negative manner and may lead to severe tire damage.
Valve caps protect the valve against dust and dirt and therefore help prevent leaks. Always screw
on caps tightly and replace missing caps.
For safety reasons, do not limit tire checks to checking the tire pressure but also check for sufficient
tread depth, ingress of foreign matter, pinholes, cuts, tears and bulges in the sidewall (cord
breakage) !

Due to changes in standards and legislation,
"V" and "ZR" tires require tire pressures that deviate
from the values indicated in the Owner's Manual.
Always use the new tire pressures indicated above. Relevant adhesive labels are available from
all official Porsche dealers.
**
In some cases, only allowed up to 2.5 bar (36 psi) in the U.S.A. This depends on the tire in
question since earlier tires have a sidewall lettering that limits the admissible tire inflation
pressure (max. press) for North America to 36 psi (2.5 bar). Lettering for tire pressures of
3.0 bar = max. press 44 psi or 300 Kpa.
