Nankang Green/Sport Eco-2+ ( 165/60 R12 75H XL )

Center sub grooves with shallower depth enhance vertical/lateral block stiffness to avert block deformation and further reduce energy consumption. Shoulder groove bottom with big angle retains shoulder block continuity, weakens block wriggling, and reduces energy consumption. Two section lateral groove on shoulder profile prevents uneven tread wear and provides adequate traction. Four circumferential groove enhances drainage performance and safety for wet road driving. Center rib reinforces straight driving and handling performance. Circumferential rib on tread shoulder, with thin sipes instead of run-through lateral grooves, prevents groove resonance and reduce noise generated by run-through lateral grooves. Adopting excellent dispersible silica and unique agents reduce rolling resistance substantially as well as enhances wet grip using unique synthetical rubber with ‘‘Chain-End Modification‘‘ strengthens fuel saving and traction. The ha-oil-free formula for all sizes conforms with EU environmental protection laws.
