Ultra High Performance Summer run-flat tires offer temporary self-supporting run-flat capabilities for up to 50 miles at speeds of up to 50 mph, even after losing all air pressure due to a puncture. These tires cater to driving enthusiasts seeking a combination of excellent performance aesthetics, precise handling, and durability rated at Z-speed or higher, while also delivering reliable traction on both wet and dry surfaces. They commonly serve as Original Equipment (O.E.) on sports cars, performance coupes, and high-performance sedans. However, it is crucial to note that these tires are not suitable for driving in near-freezing temperatures, snowy conditions, or on icy roads. O.E. Ultra High Performance Summer run-flat tires are typically bought as direct replacements for the original tired-out pairs or sets of a vehicle. Alternatively, they can also be utilized for other vehicle applications when procured in sets of four or axle pairs, provided they are available in an appropriate size, load range, and speed rating that align with the performance category and specifications of the existing O.E. run-flat tires. It is important to bear in mind that utilizing run-flat tires is only advisable for vehicles that originally come equipped with self-supporting run-flat tires and are equipped with a tire pressure monitoring system.
