The Speedball is S&M's street tire. Available in a wire bead only in a high pressure casing with extra pinch flat protection for street riders that run lower pressure. The Speedball features a multi edged S/M shoulder tread design that looks cool and holds the ground. The 20″ Speedball has a smooth unbroken center strip for less rolling resistance, while the 22″ and 26″ have a broken center tread making them  great dirt/street/park tires. The 20 x 2.1 and 22 x 22.25 are light and fast and work well in the front or rear. Big enough for today’s street riding but small enough to stay out of the way on grinds, spines, or frames and forks with minimal clearance. The 2.4 works equally well on the front and rear for riders that prefer big tires.
