Wheel Storage

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2018 Porsche Cayenne, 2017 Porsche Cayenne, 2016 Porsche Cayenne, 2015 Porsche Cayenne, and 2014 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

Tires must be stored in a cool, dry and dark room with adequate ventilation. They must never come into contact with fuel, oil, grease or chemicals. Complete wheels can be stacked for storage. It is advisable to increase the tire pressure by 0.4 bar (6 psi).

If the tires are not mounted on wheels, store them in the vertical position. Tires stored in vertical position should be turned every two weeks in order to prevent excessive flattening. If the tires are stacked in horizontal position, they will become severely deformed and cannot be seated in the rim flange easily when mounted.

Tires age due to physical and chemical processes, which can impair their function. If they are stored for an extended period, they will harden and become brittle faster than tires that are in continual use. Hairline ageing cracks can occur on older tires. If tires are in use, the kneading action activates the plasticizer in the rubber and thereby prevents hardening and cracking.
