Your winter tires should be kept in a cold, dry, and dark place. Even if they are covered with a protective covering, you should never leave your winter tires outside. Ensure that the temperature in your storage room does not surpass that of a regular room. If at all possible, avoid storing your tires outside or in a place where the temperature can fluctuate. Tires and wheels especially 30 Inch Rims left outside, even if covered, are subjected to damaging environmental changes. A climate-controlled basement, garage, or workshop is the best place to keep tires.
