Tires should be stored in a dry, cool place, away from sunlight and sources of ozone, such as electric motors. If you must store tires flat - one on top of the other - don't stack them too high. Excessive weight can damage the bottom tire.

Make sure air can circulate around all sides of the tires, including underneath, to prevent moisture damage.

If storing tires outdoors, protect them with an opaque, waterproof covering, and elevate them from the ground. Do not store tires on or over black asphalt or other heat-absorbent or reflective surfaces, such as snow-covered ground or sand. Do not allow solvents, fuels, lubricants, and chemicals to come in contact with tires.

Your vehicle's spare tire carrier or compartment is not intended to be used for long-term storage of your spare. If your vehicle has a full-size spare (the same size as all your all other tires), it should be included in the tire rotation pattern.
