Street/Sport Truck Summer run-flat light truck tires provide temporary self-supporting run-flat mobility for a distance of 50 miles at up to 50 mph, even after a puncture has allowed complete air pressure loss. They are designed for drivers who want to combine aggressive low-profile tires with large rim diameter wheels to enhance their vehicle's appearance. Sometimes used as Original Equipment (O.E.) on 2WD and 4WD pickup, crossover and sport utility vehicles, Street/Sport Truck Summer tires are not intended to be driven in near-freezing temperatures, through snow or on ice.O.E. Street/Sport Truck Summer run-flat light truck tires are typically purchased as direct replacements for worn-out pairs/sets of the vehicle's original tires. They can also be used for other vehicle applications in complete sets of four or axle pairs if available in an appropriate size, load range and speed rating to match the existing O.E. run-flat tires' performance category and specifications.NOTE: Run-flat tires are only recommended for vehicles that are originally equipped with self-supporting run-flat tires and equipped with a tire pressure monitoring system.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.
