MAXXIS TIRE MOUNTAIN SHORTY 27.5X2.30 F60TPI 3C MAXXTERRA EXO TRThis Shorty features a mid spike tread design that can handle dry, loose, blown out corners as well as a bit of mud with our 3C Maxx Grip compound. Large, tall and slightly staggered side knobs penetrate loose soil to provide predictable, stable cornering at warp speeds. The alternating pattern of the center tread features widely spaced knobs to clear debris, and their square shape offers plenty of braking bite. Available in: 26x2. 3, 26x2. 5, 27.
