Tire designed for e-bikes

The greater weight of e-bikes creates additional challenges for tires. Tires are often the most vulnerable part of a bicycle because they are its only point of contact with the ground. Rocks, roots and debris—obstacles found on a route—can damage tires. Now imagine a bike weighing 22 kg: this weight increases the load on the tire, and every obstacle can cause tire failure. That is why it is important to choose special e-bike tires that can withstand this weight without compromising riding safety and comfort. Vittoria e-bike tires use durable graphene-reinforced compounds that reduce rolling resistance and thereby extend battery life.

3 mm rubber protection

Vittoria reinforced city tires have a sturdy nylon construction and a 3 mm-thick rubber layer between the tread and casing to increase puncture protection. Graphene compounds provide a longer service life and improved 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 sturdy tire casings. Nylon threads are thicker than cotton threads, so there are fewer of them per inch. Nylon casings are strong and durable, which extends their service life. However, as a synthetic fiber, nylon is not as elastic (soft or flexible) as cotton.

Graphene technology in tires

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