When not in use, It is important to store wheels away from direct sunlight, rain, water, heat sources or sparks. They should never be stored near solvents, gasoline, motor oil, or similar substances, especially not flammable ones.
Store wheels1 hung up or lying on their sides on the floor.
Never hang up tires not installed on rims for storage. Store them standing upright or lying on their sides instead. If you hang up rimless tires, they may become deformed.
