S&M Bikes Speedball 29x2.40" Tire: The Speedball is a street tire. Available in a wire beaded high pressure (70 PSI) casing with extra pinch flat protection for street riders that prefer to 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" versions have a broken center tread making them great dirt/street/park tires as well. The 20" x 2.10" and 22" x 2.25" are light and fast and work well in the front or rear. Big enough for street riding but small enough to stay out of the way on grinds, spines, or frames and forks with minimal clearance. The larger 2.40" sizes work equally well on the front and rear.
