Front knobs: arrow-like layout and side knobs for directional accuracy and straightaway visibility; V-shaped knobs improve braking stability and cornering side hold Grip and traction on a wide range of terrain (from mid soft to mid hard) Perfect application for training; optimal compromise between performance and durability Tread pattern taken from previous design with a new front similar to the Scorpion MX Soft 410 Multi-ply carcass with high resistance to punctures but maximum flexibility to absorb forces during jumps or obstacles Training performance in all terrain conditions with uniform knob wear, resistance to deformation while damping and thus an extended durability DOT approved Tube type Bias-Ply
