Some of the biggest tire manufacturers, including Bridgestone/Firestone and Michelin, however, have issued bulletins to retailers calling for tires to be removed from service 10 years after the date of manufacture. The bulletins note that consumers should follow the tire replacement recommendations in their vehicle owner's manual if they offer different advice on a tire's shelf life. Ford, Chrysler, BMW, Audi and Toyota all recommend that tires be replaced six years after they were made.
Because of those bulletins, tire retailers should not be selling tires close to or older than 10 years of age, according to Sean Kane, who heads a private auto safety firm. "It's shocking to hear that particularly now because companies, like Sears, these large tire retailers have had this information in their hands for some time," said Kane.
