Select Vehicle or Tire SizeThe Direzza ZII Star Spec is Dunlop's Extreme Performance Summer tire developed for serious sports car, sports coupe and performance sedan enthusiasts looking for race tire-like traction on the street or for use in autocross, drifting and track events.
As an evolution of the Direzza ZII and continuing to use the same tread design, the Direzza ZII Star Spec's tread compound helps provide faster lap times from the start by developing more traction in temperate temperatures along with consistent grip on subsequent laps when the tires are fully warmed up. While this means the Direzza ZII Star Spec's tread compound accommodates a wider operating temperature range, it is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.
Dunlop'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."
Direzza ZII Star Spec tires confirm their "Star Spec" identity in the form of a 5-pointed star symbol branded adjacent to the "Direzza ZII" name on the sidewall. However, this 5-pointed star should not be confused with the same symbol often branded by tire manufacturers on the sidewalls of Original Equipment tires for BMW vehicles.
Direzza ZII Star Spec's high-grip tread compound is molded into a directional design with a continuous center rib flanked by massive shoulders that form a highly rigid tread that delivers high levels of dry grip and handling while promoting uniform tire temperatures and even wear across the tread. Two wide circumferential center grooves channel water through the center of the tread design while angled independent grooves help direct water to the sides of the footprint to enhance wet traction.
The Direzza ZII Star Spec features Dunlop's True Circle Profile that distributes tire deflection forces along the sidewall to provide more control by better communicating tire performance limits to the driver. Its internal structure includes JointLess Band (JLB) Technology that spirally winds polyamide cord over the two wide steel belts to promote strength, uniform ride quality and high-speed capability while 2-ply polyester sidewalls help resist lateral deflection to provide responsive handling and cornering stability.
Note: We recommend installing Direzza ZII Star Spec tires in sets of four to fully realize their benefits.
El neumático Direzza ZII Star Spec de Dunlop pertenece a la categoría: Rendimiento Extremo Para Verano y fue desarrollado para entusiastas de autos verdaderamente deportivos, cupé deportivo y sedanes de rendimiento, que buscan una tracción similar a la experimentada en carreras, aunque, su uso sea en carreteras, competencias autocorss, derrape o de circuito.
El Direzza ZII Star Spec evoluciona del Direzza ZII y continúa utilizando el mismo diseño de huella, aunque, el compuesto de caucho nuevo, ayuda a obtener tiempos más rápidos por vueltas, debido a una mayor tracción en temperaturas moderadas desde el inicio de la carrera, y un agarre constante, en las subsiguientes vueltas, cuando el neumático está caliente. A pesar que el Direzza ZII Star Spec, puede trabajar en un abanico más amplio de temperaturas, no debe ser guardado o manejado en temperaturas cercanas al nivel de congelación o superficies con hielo o nieve.
La garantía Dunlop establece: "Neumáticos de Ultra Alto Rendimiento Para Verano no son recomendados para uso en invierno. Rajaduras en los hombros o banda de rodamiento, producto de su uso en invierno, no serán cubiertos bajo nuestra garantía".
La identidad "Star Spec" del Direzza ZII Star Spec, es confirmada con un símbolo de una estrella de cinco puntas, ubicada al lado del nombre "Direzza ZII" en el flanco o pared. Este símbolo, no debe ser confundido, con el mismo que utiliza BMW, para identificar sus neumáticos originales (O.E., por sus siglas en inglés).
El compuesto de caucho de agarre fuerte, utilizado en el Direzza ZII Star Spec, es moldeado en un diseño direccional, con un segmento central continuo, flanqueado por hombros grandes que dan rigidez a la banda de rodamiento, y así, obtiene niveles altos de agarre sobre superficies secas y maniobrabilidad. Al mismo tiempo, proporcionan temperaturas uniformes y un desgaste parejo del neumático. Dos canales circunferenciales anchos sacan el agua del centro de la huella, mientras que, ranuras anguladas independientes expulsan el agua hacia los lados, para mejorar la tracción.
El Direzza ZII Star Spec utiliza la tecnología "True Circle Profile" de Dunlop, la cual permite distribuir las fuerzas de torsión a lo largo del flanco, con la idea de proporcionar mayor control, al establecer mejor comunicación de los límites de desempeño del neumático con el conductor.
La estructura interna del Direzza ZII Star Spec incluye la tecnología "JointLess Band" (JLB, por sus siglas en inglés) que envuelve cordón de poliamida en forma espiral, por encima, de dos correas anchas de acero, para proporcionar fortaleza, un andar uniforme y de calidad, a la vez, de mayor capacidad para soportar velocidades elevadas. Correas de poliéster, 2-ply (capacidad de tela), en los flancos ayudan a resistir la torsión lateral, para proporcionar maniobrabilidad responsiva y estabilidad al tomar curvas.
Nota: Para obtener todos los beneficios del Direzza ZII Star Spec, recomendamos instalarlos en juegos de cuatro.
