Temperature
The storeroom temperature should be below +25 ºC (77ºF), maximum. Ideally, it should be dark and below +15 ºC (60ºF). If the temperature is above 25 ºC or below 0 ºC (30 ºF), the properties of rubber may change, thereby affecting the final service life of the tire. Cool storage does not have any adverse effect on rubber products.
Humidity
Extremely humid conditions should be avoided. Humidity in the storeroom air must not be so high that condensation occurs on the tires. Tires must not be stored in conditions where they are exposed to rain, splashes, etc.
Light
Tires must be protected from light, particularly from direct sunlight and intense artificial light with a high ultraviolet content.
Oxygen and ozone
Ozone has a very strong deteriorating effect on tires. The storeroom must not contain any ozone-producing equipment, such as fluorescent lamps or mercury vapor lamps, high-voltage electrical equipment, electric motors or any other electrical equipment that may generate sparks or silent electric discharges.
Deformation
If possible, tires should be stored freely in their natural form, so that they are not under stress, pressure or torsion. Strong deformities developed during long-term storage may break when pressurised.
Solvents, oils, greases, heat
Tires must be particularly protected from any contact with solvents, oils or greases, however short-term. Tires must also be protected from powerful emitters of light and spatter from electric welding.
Tire handling
When handling tires in warehouse don`t ever drop tires higher than 1,5 m (5 ft). Tires could be damaged on drop from bead area, thereby causing a kinked bead.
If you find a tire with kinked bead, we do not recommend mounting it to a rim.
