Vittoria MTB tires – the only ones using 4 compounds in one tread
Vittoria 4 compounds (4C) layering technology features separate base and surface compounds, in both the center and the side areas of the tread. This approach enables the Vittoria team to fine-tune the flex of the tread-base and tread-surface separately, placing the correct compound exactly where it is needed for maximum cornering, climbing, rolling, braking, and wet grip performance. All Vittoria Cross-Country and Enduro tires use the 4C technology.
