Proper Storage Can Slow Down the Ageing of Tires 1. TemperatureThe storeroom temperature should be below 77 ºF, it should preferably be dark and below 59 ºF. The properties of rubber may change, affecting the final service life of the tire, if the temperature is above 77 ºF or below 32 ºF. Cool storage does not have any adverse effect on rubber products. 2. HumidityExtremely 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. 3. LightTires must be protected from light, particularly from direct sunlight and intense artificial light with a high ultraviolet content. 4. Oxygen and ozoneOzone has a very strong deteriorating effect on tires. The storeroom must not contain any ozone-producing equipment, such as fluorescence lamps or mercury vapour lamps, high-voltage electrical equipment, electric motors or any other electrical equipment that may generate sparks or silent electric discharges. 5. DeformationIf possible, tires must be stored freely in their natural form, so that they are not under stress, pressure or torsion. Strong deformities developed during long-time storage may break when pressurised. 6. Solvents, oils, greases, heatTires 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. 7. Tire handlingWhen handling tires in warehouse don`t ever drop tires higher than 5 feet. Typical consequence could be kinked bead. If you find a tire with kinked bead we do not recommend you mount that tire to a rim.
