Technologies

3 mm rubber protection: Vittoria reinforced city tires use a strong nylon construction and a 3 mm-thick rubber layer between the tread and casing to increase puncture protection. Graphene compounds help extend service life and improve performance in wet weather. The tires use rigid beads, which are well tested and easy to use with inner tubes.

Nylon casing: Nylon is a strong, durable synthetic fiber traditionally used to make robust tire casings. Nylon threads are thicker than cotton threads, so there are fewer threads per inch. Nylon casings are strong and durable, which extends their wear life. However, as nylon is a synthetic fiber, it is not as elastic (soft and flexible) as cotton.

Graphene technology in tires: Vittoria uses graphene in tire compounds to improve tire performance. Graphene is the thinnest material in the world and one of the strongest materials ever used in consumer products. It consists of a single layer of carbon atoms arranged in a hexagonal pattern. Graphene interacts with rubber by filling the space between rubber molecules. It acts like a magnet, bringing the rubber molecules closer together and improving the overall structure of the rubber. Graphene’s key properties are thinness, strength, flexibility and lightness. In MTB tires, GRAPHENE 2.0 improves wet-surface grip across all product lines.
