The all-new Roadsmart IV delivers best-in-class handling, grip, and mileage. Featuring a completely new tread pattern, construction, compounds, profiles, and new technology.

Features:

• New tread patterns, constructions, compounds, and profiles increase ride comfort, grip and mileage.
• Multi-Tread™ (MT) technology in the rear tire utilizes a high-mileage compound in the center and high-grip compounds on the shoulders.
• Performance Compound Layers Progressive (PCL Progressive) technology accelerates tire warm-up and allows the RSIV to maintain its high-performance throughout its lifespan.
• Front and rear compounds with Hi Silica X and Fine Carbon increases mileage, wet grip and stopping performance.
• Slim High Bead Apex enhances tire performance by reducing rigidity and improving shock absorption of the sidewall.
• A new Bead Profile inhibits float from the bead area on the rim, which improves traction and slide control by minimizing buckling at full lean angle.
• Optimized profiles and tread patterns create more nimble and neutral handling, improve wear characteristics and wet-weather performance, and reduce rigidity.
