TECHNOLOGY

1.3 mm Rubber protection:Vittoria reinforced city tires use a robust and dependable nylon construction and a 1.3-millimetres-thick rubber braker placed between the tread and the casing for increased puncture protection. Rigid beads are used, as they are long proven, and provide ease of use with inner-tubes.

Nylon Casing:Nylon is a robust and durable artificial fiber traditionally used for strong tire casings. Nylon threads are less thin than cotton ones, so casings have a lower number of threads per inch. The advantages of nylon casings is that they are strong and durable, extending the wear life of the casing. However, because it is an artificial fiber, it is not as supple (soft/flexible) as cotton.

About GRAPHENE technology in tires:Graphene is the innovative material used by Vittoria in compounds to improve performance of tires. Graphene is the world’s thinnest material but at the same time one of the strongest ever used for consumer applications. Made of a single hexagonal-shape layer of carbon atoms, Graphene interacts with rubber by filling the space in between the rubber molecules. It acts like a magnet, making rubber molecules closer to one another and improving the overall rubber structure. Graphene’s main properties are related to: Thinness / Strength / Flexibility / Lightness.
