If stored in unfavourable 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.
Tires should never be stored in the open air, even under a protective covering.
Tires should be stored in a cool, dry area, moderately ventilated and away from direct sunlight.
Storage temperature must not exceed normal room temperature. In heated areas 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, to tires the storage area must not contain any devices ( electric generators or compressors) that generate ozone.
Solvents, fuels, lubricants, chemicals etc. should not come into contact with tires.
