System 3 Off-Road XCR350 X-Country radial tires are available in a variety of sizes for ATV and UTV applications. The 8-ply-rated radial carcass is light and flexible; while the medium compound lets the tread blocks flex for predictable and precise handling. A multi-angle tread design features stepped structure for maximum bite, and a staggered shoulder tread enables traction across the entire tread surface. All sizes (except the 36 in.) are DOT marked.
