Kumho ECSTA PS91

The Kumho Ecsta PS91 tires feature a notched center rib which reinforces the block through the C-Cut 3D design, resulting in stability and enhanced handling. The heat dimples readily dissipate thermal buildup in the tires to allow reaching higher speeds without damaging tires owing to excessive heat. The tires also feature four wide circumferential grooves which increase wet grip. The tread compound is comprised of Carbon Black and Silica with Max Grip Performance Resin which gives them the bleeding edge to push past conventional limits.
