GT Radial Champiro 228
The GT Radial Champiro 228, available in 30 sizes, is marketed by GITI (USA) Ltd. as a "performance tire for drivers desiring more than a smooth ride, comfort and excellent grip" but "who also expect eco-friendly and fuel efficient tires."
This performance touring tire features a Nanotek silica compound for reduced rolling resistance and strong grip in wet and dry conditions. Nanotek silica is a manufacturing technology process which utilizes Nano-grade silica nodules.
These nodules, which are smaller than traditional silica nodules, are mixed into GITI's specially formulated polymer-caron black matrix by employing a silane-based coupling agent and a proprietary mixing technique. The result is a product that provides the lower rolling resistance along with the improved wet handling performance.
