Use a tire protectent to prevent the ravages of ultraviolet light or ozone damage in the summer and harsh weather conditions in the winter. Be sure to clean tire sidewalls with Armor All or a similar product. Whenever your vehicle is stored for long periods of time (a classic car, for example), cover your tires and remove the vehicle's weight or load to help prevent sidewall cracks from forming.
