Max Performance Summer run-flat 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 serious driving enthusiasts who want a combination of a performance appearance, competent handling and Z-speed rated (or higher) durability with enhanced dry and wet traction. Often used as Original Equipment (O.E.) on powerful sports cars, performance coupes and high performance sedans, Max Performance Summer run-flat 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. Max Performance Summer run-flat 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.Limited sizes of the Goodyear Eagle F1 Asymmetric 2 RunOnFlat are available with Goodyear's SoundComfort Technology, which involves the manufacturer adhering a layer of sound-absorbing foam to the inner liner of the tire to reduce cabin noise in the vehicle. These sizes are identified on the Specs page and in the search results. Related Information: Learn more about MOExtended/MOE tires here.
