The TURANZA GR-100, in its new tread design, features rib-linked blocks that uniforms ground contact when braking and enhances wet braking performance. With its optimized 3D block shape, the TURANZA GR-100 also minimizes contact lift off. Plus, the TURANZA compound in its material makes for reduced friction which in turn minimizes energy loss.All of its materials have optimized balance for improved rolling resistance without compromising its durability. When compared to conventional tires, the Turanza GR-100 has up to 7.1% less CO2 emissons and up to 2.5% better fuel consumption!
