The HTR Z II (High Technology Radials-2nd generation) is Sumitomo's Ultra High Performance Summer tire developed for the drivers of sports cars, sporty coupes and performance sedans. The HTR Z II is designed to blend a unique appearance, dry and wet performance and ride comfort. Like all summer tires, the HTR Z II is not intended to be driven in near-freezing temperatures, through snow or on ice.
The HTR Z II molds a high performance tread compound featuring ultra micro carbon technology and silica-based rubber into a directional pattern that features wide, arched tread blocks to enhance dry road traction and handling. A circumferential center rain groove and multi-direction water channels resist hydroplaning and enhance wet traction. The tire's internal structure features two steel belts with spirally wrapped Jointless Nylon Band reinforcement to enhance high-speed durability while minimizing weight and improving ride uniformity. The lower sidewall features Single Strand Beads for improved wheel fit and Wheel Flange Guards to help protect alloy wheels from accidental curb damage.
NOTE: Sumitomo reassessed the HTR Z II line’s UTQG ratings in 2009. This resulted in tires featuring the same design, materials and manufacturing methods previously rated 220 AA A to be assigned UTQG ratings of 360 A A. Sumitomo has confirmed that regardless of the branded UTQG ratings, all HTR Z II tires are fully compatible and may be mixed individually or in pairs as necessary.
El neumático HTR Z II (High Technology Radials-2nd generation) de Sumitomo, pertenece a la categoría: Ultra Alto Rendimiento Para Verano y fue desarrollado para conductores de autos deportivos, cupé deportivo y sedánes de rendimiento. El diseño del HTR Z II combina una apariencia única con buen rendimiento sobre superficies secas y mojadas, y un andar confortable. Como todo neumático de verano no fue diseñado para ser utilizado en temperaturas cercanas al nivel de congelación o superficies con hielo o nieve.
El HTR Z II posee un compuesto de caucho de alto rendimiento que utiliza la tecnología micro carbón y un caucho con base de sílice. La banda de rodamiento posee un patrón direccional con bloques anchos en forma de arco, para mejorar la tracción y maniobrabilidad sobre superficies secas. Un canal central circunferencial y ranuras con diferentes direcciones aumentan la tracción sobre superficies mojadas y ayuda a resistir el deslizamiento sobre agua (hydroplaning).
La construcción interna cuenta con dos correas de acero reforzadas con una banda de nailon envuelto en espiral, sin uniones que permite mayor durabilidad para altas velocidades, a la vez, minimiza el peso y mejora la uniformidad del andar. La parte baja del flanco posee una sola hebra (Single Strand Beads) como alambre del aro o talón para mejorar el ajuste con el rin, además tiene una pestaña que protege los aros del daño causado por las aceras.

*Tire Rack's Tire Warranty Rating is an overall rating given to tire warranties after subjectively evaluating their value for the consumer. Warranties are rated on a scale of 0-5 with 5 being the highest. This rating combines all of the aspects of each tire's warranty where applicable, including: mileage/treadlife, materials and workmanship, balance and uniformity, replacement tire cost, warranty duration and any special manufacturer's warranties that apply. See official manufacturer's warranty brochure for specific details.
NOTE: New vehicle Original Equipment tire warranties often differ from those covering replacement tires. Consult your vehicle documents to confirm Original Equipment tire warranty coverage.
The Original Equipment applications for this tire are not available online at this time. Please call 888-541-1777 to speak with one of our sales specialists. We apologize for any inconvenience this may cause.
