The XBRI Ecology tire is a member of the ultra-high performance category. It is designed to give performance and confidence to drivers of high-performance sedans by providing abundant traction, precise handling and positive steering response on dry and wet roads. The exterior features a specially formulated tread compound molded into a six-rib directional tread design to provide tread rigidity for improved traction, steering response and cornering stability. . The continuous center rib of the tread design provides constant rubber-to-road contact to improve straight-line tracking and reduce noise levels. The placement of the wide circumferential and angled side grooves combines dry road performance with wet weather traction and hydroplaning resistance.
