Accelerated rubber breakdown, which is commonly seen on tires as cracking and dry rot, will affect your spare tire even though it remains stationary on the back of your vehicle or trailer until you need it. The rubber of most tires contains protective waxes that are released to the surface when you drive on it. Because you're not using your spare, it's more vulnerable to damage caused by exposure to UV rays and ozone. In short, your spare tire will wear out even if its rubber has never met the pavement. A spare tire cover is one way you can combat this form of wear.
