If stored in unfavorable conditions, or if not properly handled, tires change their physical properties. This can lead to a shorter service life, and the tires may even deteriorate to the extent that they become unusable. Correctly stored and handled tires retain their properties virtually unchanged for several years.
Storage in the open air, even under a protective covering, is not permitted.
A storeroom for tires should be cool, dry and dark and should be well ventilated. Storage temperature must not exceed normal room temperature. In heated rooms the tires must be shielded from the heat source.
The tires must be protected from direct sunlight and continuous changes of air. As ozone is particularly damaging, storerooms must not contain any devices that generate ozone.
Solvents, fuels, lubricants, and chemicals should not be kept in tire storerooms or come into contact with tires.
Ensure that tires are not stored under pressure to avoid cracks.
Minimizing storage time helps avoid damage.
