This 315/30R21 fitment features Audi Original Equipment (AO) specification, designed to meet the exacting standards of premium European sports cars.

Performance Technology:

  • Dynamic Response Technology: Hybrid belt construction using aramid and nylon ensures instantaneous steering response and optimum transmission of driver inputs to the road surface
  • Motorsport-Derived Tread Design: Ultra-reactive tread pattern developed from Formula E and WRC racing experience continuously adapts to road conditions for maximum contact patch optimization
  • Premium Wet Performance: Advanced compound featuring functional elastomers and hydrophobic silica particles delivers exceptional wet grip and shorter braking distances
  • Enhanced Water Evacuation: Wide, deep longitudinal grooves provide superior hydroplaning resistance and water drainage in wet conditions

Audi Original Equipment (AO) Specification: This tire carries the AO designation, indicating it was developed in partnership with Audi to meet their specific performance, handling, and safety requirements. The Pilot Sport 4 delivers the ideal balance of dry handling precision, wet weather confidence, and refined ride quality that premium sports car drivers demand.
