Key Features & Performance Advantages
- Eco Tread Compound: High-silica formulation minimizes energy loss during tread deformation, reducing overall rolling resistance and fuel consumption.
- Advanced Drainage System: Four main longitudinal grooves combined with lateral sipes accelerate water evacuation for short braking distances on wet roads.
- Optimized Tread Footprint: Uniform ground contact distribution prevents irregular tread wear, extending total tire service life.
- Quiet Cabin Comfort: Computer-optimized multi-pitch block arrangement disrupts acoustic frequency patterns to lower road noise.
