Kumho Ecsta PS91 Best

The Ecsta PS91 is engineered with an innovative new carbon black compound enhanced with silica and Max Grip Performance Resin that forms into an asymmetric tread pattern. These features improve handling on wet and dry roads as well as bolstering cornering grip. Kumho employs a 3-D Dimple Design that reduces heat buildup in the tread blocks to enhance tread life, durability, and overall performance. A notched, continuous center rib is coupled with stiff tread blocks to accelerate steering responsiveness and stability. A group of four circumferential grooves work in conjunction with slanted lateral grooves to evacuate water away from the tire and enhance wet traction. Internally, the Ecsta PS91 is reinforced with dual nylon cap plies that amplify handling responsiveness, stability, and durability.
