The Dunlop Roadsmart IV redefines sport-touring performance through advanced material science and structural engineering. By integrating Hi Silica X and Fine Carbon into both front and rear compounds, the tire delivers enhanced mileage, superior wet grip, and improved stopping power. The rear tire features Multi-Tread™ (MT) technology, which strategically places a high-mileage compound in the center alongside high-grip compounds on the shoulders to balance durability with cornering capability. This is further supported by Performance Compound Layers Progressive (PCL Progressive) technology, which accelerates warm-up times and ensures consistent high-performance output throughout the tire’s lifespan.
Structural refinements focus on optimizing handling dynamics and ride quality. The new Bead Profile inhibits float from the bead area, minimizing buckling at full lean angles to improve traction and slide control, while the Slim High Bead Apex reduces sidewall rigidity to enhance shock absorption. Combined with optimized profiles and new tread patterns, these design elements create more nimble, neutral handling characteristics. The result is a tire that improves wear consistency and wet-weather performance while reducing overall rigidity, offering a refined balance of comfort, grip, and longevity.
