Offering drivers high performance and security, Yokohama Tire’s ADVAN Sport ZPS (Zero Pressure System) run-flat tire can be driven up to 50 mi (80 km) at 50 mph (80 km/h) after the loss of air. The tire provides strength from the inside, where it uses rigid sidewall reinforcement with a low heat-generating compound that is designed to support the weight of the vehicle during loss of air pressure. A bead-filler delivers a comfortable ride during normal operations and high rigidity under zero-pressure conditions. An extra-thick bead wire placed in a hexagonal arrangement allows for easier fitting to the rim and reduces the risk of bead unseating after loss of air pressure. Available in 13 sizes to fit high-performance vehicles such as the BMW 3 Series, Yokohama’s nanotechnology tread compound also provides additional grip from the outside.
