- Low Rolling Resistance (LRR) technology utilizes high dispersion silica (HDS) that strengthens the molecular structure of the rubber to improve fuel economy up to 5% and provide lower operating cost per mile. - Eco-friendly design reduces rubber dust particle emission by 10% without sacrificing performance attributes like ride comfort, noise levels, steering stability or all-season traction in wet conditions. - Anti-abrasion carbon black technology with HDS improves wear resistance and maintains high traction capability in both wet and dry conditions for better gas mileage, performance and comfort - all while reducing its carbon footprint. - Kumho's proprietary noise simulation know-how delivers exceptionally low noise operation. - Durable belt construction including two full-width steel belt layers, high-tensile bead wire construction and lower rolling resistance mold profile provides strength, durability, ride comfort and better fuel economy.
