Original Equipment (O.E.) self-supporting run-flat summer tires are an appropriate tire choice for sporty vehicles manufactured in the U.S., as well as those imported from Europe and Asia. Developed for use on new cars and light trucks, these tires offer temporary extended mobility in the event a puncture allows complete pressure loss, as well as provide a sporty blend of ride quality, noise comfort and handling, along with dry and wet traction. These tires are not intended to be driven in near-freezing temperatures, through snow or on ice.
Dunlop Self-Supporting Technology (DSST) tires incorporate special sidewall reinforcements that support the weight of the vehicle even after sustaining air pressure losses that would render conventional tires immobile. While internal tire damage will likely make replacement necessary, DSST tires are designed to endure being run on while flat for up to 50 miles at speeds up to 55 mph and provide drivers the temporary extended mobility necessary to drive through stormy weather and away from dangerous situations.
Original Equipment self-supporting run-flat summer tires are most often repurchased as direct replacements for pairs and sets of worn out Original Equipment tires and DSST tires are only recommended for vehicles originally equipped with self-supporting run-flat tires and a tire pressure monitoring system.
While we attempt to provide a picture of as many of these tires as possible, the pictures used to represent these tires cannot be guaranteed to be an exact depiction of each tire’s appearance because of the variety of subtle differences in tread designs and sidewall styling.
Though they cannot be labeled as run-flat tires, tires branded with MOExtended or MOE on their sidewalls offer run-flat-like characteristics by delivering limited temporary extended mobility after a puncture results in complete loss of air pressure. Because MOExtended or MOE tires do not have the same speed and distance endurance of conventional run-flat tires, they should not be substituted in any situation where a conventional run-flat tire is required. To confirm what your vehicle needs, check our Original Equipment tire listing for your year, make and model or see your vehicle owner’s manual.
