Key Features:

• Asymmetric Tread Design: Features distinct inner and outer tread patterns to provide balanced performance in various conditions. The outer longitudinal grooves are designed to enhance wet grip and handling.  
• Excellent Wet Grip (EU Label A): The large groove design and an advanced compound with melt-polymerized styrene-butadiene and silicon deliver exceptional grip on wet roads, often achieving an "A" rating on the EU tire label.  
• Low Noise: A 5-pitch and multi-steel disc pattern design effectively reduces rolling noise for a quieter and more comfortable ride.  
• Fuel Efficient Performance: The silicon-based compound helps lower rolling resistance, leading to improved fuel economy.  
• All-Season Traction: The asymmetric tread pattern, along with optimized sipes and grooves and a specialized compound, offers good traction in dry, wet, and light winter conditions.  
• Enhanced Controllability: Continuous center ribs in the asymmetric pattern maximize the tire's contact with the road, resulting in improved steering responsiveness and enhanced driving stability.  
• High-Speed Durability: A heat-resistant compound and even pressure distribution across the tire's footprint enhance its durability and performance at high speeds.
• Comfortable Ride: The 5-pitch and multi-steel disc pattern also contribute to reducing road noise and vibrations, increasing driving comfort.  
• Rim Protector: Many sources indicate the presence of a rim protector to help prevent wheel damage from curbs. It's advisable to confirm with the seller.
