Flat Tire - Porsche 718 Cayman GT4RS 2023 Owner's Manual

Storing wheels
e
Always store wheels in a cool, dry and dark place.
Store tires without rims vertically.
e
Do not store summer tires or vehicles with
mounted summer tires at ambient temperatures
under 5 °F (–15 °C).
e
Avoid contact with gasoline, oil or grease.
e
Do not use tires that are more than 6 years old.
Chemical additives, which make the tire rubber
elastic, lose their effectiveness over time and the
rubber becomes brittle. The age of the tire can
be seen from the "DOT" code number shown on
the tire sidewall. If the last four digits read 3015,
for example, then the tire was produced in the
30th week of 2015.
