The Maxxis Minion DHR II 27. 5 inch Tire improves upon the solid design of its predecessor to give you reliable performance on the toughest, most technical trails. The DHR II's redesigned shoulder knobs offer a wider stance and better cornering than the original DHR, and the paddle like knobs on the center tread improve breaking and provide better traction on loose ground. The center tread features ramped knobs for improved acceleration and sipes for smooth transitions. The Minion DHR II has 60tpi casing and is equipped with EXO sidewall protection technology, a semi rigid fabric that is incorporated into the sidewall to prevent flats and abrasion.
