Tread design is complex and controversial aspect of tyre design. Over the years, Vittoria has acquired the experience of many millions of kilometres racing on every kind of road. For most surface conditions we know what works. At the same time, we are forever questing for new approaches to provide riders with yet more grip and security, whether eking out the last watt of power in a pursuit, cornering on the limit on a rainy descent, or commuting to work on broken roads. |

Prisma C.O.M. Vector Design is our breakthrough tread – a complete re-design of the traditional regular-diamond pattern. Each diamond micro-knob, or ‘prism’, is of a different size and shape. Computer-aided engineering allowed us to shape every prism optimally. Prisms close to the smooth, central tread are small, and their rhomboidal base elongated in the direction of travel. Prisms close to the tyre’s shoulder are larger, and their base elongated at rightangles to the direction of travel. This reduces straight-line rolling resistance, optimizes grip in corners, and sheds water even more effectively. |

Twin Tread is a simple but provenly effective way to improve performance. The tread compound at the crown, where the tyre runs most of the time, is optimized for speed and long life; while the compound at the shoulders, comparatively little used, is much softer and grippier, for secure cornering. |

Aquaflow derives from car-tyre technology, introducing carefully shaped channels, or ‘sipes’, across the tyre’s tread, to drain water away and let the tyre grip the surface more effectively used in all our range. |
