The Speedball features a multi edged “S&M” shoulder tread design that looks cool and holds the ground while turning. The 20″ Speedball with its smooth unbroken center strip for less rolling resistance is primarily a street tire, while the 22″, 26″ and 29” versions have a broken center tread making them great dirt/street/park tires as well. The 20” x 2.25” 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. 20 x 2.25: Inflated Width: 2.25″ (57.15mm)Inflated Diameter:Max Pressure: 110 psiWeight: 20 x 2.40: Inflated Width: 2.41″ (61.2mm)Inflated Diameter: 21″ (533mm)Max Pressure: 110 psiWeight: Black – 737 g (26 oz) 22 x 2.25: Max Pressure: 70 psiInflated Width: 2.2″ (55.9mm)Inflated Diameter: 22″ (559mm)Weight: 850 g (30 oz) +/-5% 22 x 2.40: Max Pressure: 70 psiInflated Width: 2.35″ (59.7mm)Inflated Diameter: 22.25″ (565mm)Weight: 878 g (31 oz) +/-5% 26 x 2.40: Max Pressure: 70 psiInflated Width: 2.35″ (59.7mm)Inflated Diameter: 26.5″ (673mm)Weight: 1105 g (39 oz) +/-5% 29 x 2.40: Max Pressure: 70 psiInflated Width: 2.35″ (59.7mm)Inflated Diameter: 28.875″ (733mm)Weight: 1105 g (39 oz) +/-5%
