Wheels / tires - general notes
The service of storing a customer's wheels is one which is now almost taken for granted. For this reason, we have published this BMW Technical Service bulletin to provide a uniform storage concept, which will prevent damage being caused due to incorrect storage.
The tire's rubber will age under the influence of sunlight, heat, humidity, movements in the air and ozone, and will thus lose some of its stability and elasticity. For this reason, tires should never be stored in the open-air. If open - air storage cannot be avoided, the wheels / tires must be stored in a clean and dry condition and covered with waterproof material. It is essential that wheels / tires are protected against rain, snow and sunlight, but due to the risk of corrosion they must not be stored in tire sacks. For more information on protective covers for wheels and tires,
Wheels / tires with tire pressure control (RDC) must not be cleaned with high-pressure cleaning equipment.
