P Zero RK
It is the product range for asphalt rallies
Thanks to its two longitudinal grooves, this product, designed for asphalt, can be used both in dry and damp conditions. The two longitudinal channels are positioned on the internal part of the tyre to ensure more effective directionality and avoid aquaplaning. The outer part of the tread due to the asymmetric profile presents a flatter and less grooved footprint which contributes to maximising grip and lateral stability.
