When not in use, It is important to store wheels away from direct sunlight, rain, water, heat sources or sparks. You should never store them near solvents, gasoline, oils or similar substances – especially flammable ones.
Store wheels1 hung up or lying on their sides on the floor. Never hang up tires not installed on rims for storage. Be sure to store them standing upright or lying on their sides. If you hang up tires without their rims, they may become deformed.
