The S&M Speedball Tire features a low profile, micro knurled tread pattern with smooth centerline for minimal rolling resistance. A multi-edge S/M tread design on the shoulders provides additional traction and strong sidewalls offer extra pinch flat protection for those who run lower air pressure. These tires are available in multiple widths and wheel sizes.
