P Zero RK
This is the product range for asphalt rallies
Designed for asphalt use, this product features two longitudinal grooves that allow it to be used in both dry and damp conditions. The centrally positioned grooves help support directional stability and water management. The outer section of the tread has a flatter, less grooved profile, which contributes to improved grip and lateral stability.
