Successive pattern to Charybdis. It's robustness enables to drive in heavy mudy terrain. Special form of the pitch finds easy stand in hard, broken terrain (stones, roots), where the profile hooks as "clutches" of the mythical Harpie and doesn't loose up. The milled bottom of0the profile increases the adhesion during the contact with the hindrance. The characteristical shape of Harpie is reliable also on grass and in soft surface, where the depth of the pattern secures stability along with the side reinforced pitch. Harpia in combination with the technology "CUT ENEMY" decreases the risk of puncture. It is a perfect choise for safety and long durability.
