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.Goodyear's warranty states: "Ultra high-performance summer tires are not recommended for winter use, and tread or shoulder cracking on those tires resulting from winter use will not be covered under our warranty."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.
