Nankang AS-2+ 255/35 R19 96Y Run Flat

The void ratio of the inside and outside are respectively 38% and 34%, and it can improve tire’s drainage efficiency and also wet handling. With broadened circumferential groove width, the section area of inside/ outside grooves are increased 21.3% and 43.8% respectively compared to the conventional design. And it can increase the volume to contain... moremore water for better drainage performance. Brand new profile design and reinforced sidewall design can upgrade tire stiffness. Serrated wall of circumferential groove: Discharge water in the circumferential grooves promptly and effectively, as well as reduce the noise caused by the friction between airflow and groove wall. For inside and outside lateral groove on tread shoulder, we use chamfering design to optimize the angle of lateral grooves, and it can reduce tire’s rolling sound and improve block stiffness effectively.
